Thank You to Dave Martindale, Gary Saunders, Jim Miller, and the Tech staff at Garmin. Each of you played a critical part in getting this little project resolved. A few points that anyone might pass on to others, the commands to the GPS-20 must be followed by a CR and LF, best done from a simple terminal program with a Control M followed by a Control J. Once that little breakthrough was learned, two of the messages told me to be careful, everything else went very quickly. Now those who are looking for signals from a project here can be sure that the signals left here consistently within a few milliseconds of the agreed time without having to try and set a PC Clock over a MODEM connection every day or so. The date information will allow full automagic recovery from power outages which has been a long time desired capability.

I first examined the numbers to see if we had any outlyers and after some tests found that all the excursions of the lat and long were smooth and the data was wonderfully consistent. After looking at the numbers however I have some need of some mentoring from one of the members of this list. As I examined the numbers I have come to sense that the numbers are just a little to far apart from the max to the min, beyond what I expected. Are my expectations real? Well maybe not but that is the end question so let me digress for a moment. These Lat and Long figures are from a 24 hour + a bit sample of some 87000 seconds, surely the numbers should be significant in such a sample, but that might also be a question maybe. My Lat is determined to be 4439.7891 min and 4440.3038 max and the Long is 7622.7170 min and 7623.6471 max. The differences are .6147 with an average of .3074 for the Lat and the Long difference is .9301 for an average of .4650. Just for fun I sent the ancient 386sx away for a while to calculate the real average and the difference is in the noise, for that at least I am glad - everything seems to be following a nice Normal curve. >From my rule of thumb book, a degree is ~~70 Miles, then one minute is 1.2 miles and 1 second is about 100ft at the equator. Again, my rule of thumb book may be out of date but if it is not.... At my Latitude a second is then about 50 ft. I also have no idea what the chap who is pushing the numbers into the system to manage the SA, but assuming nothing drastically out of the norm, ie nothing in the press about any issues, lets assume that the SA is normal. For this location then the (my word) jitter is say 18 seconds for the Lat and again 27 seconds for the Long. These look to me to be a little beyond what I was expecting, for say worst case of about 8 seconds of error. The real figures are 2 to 3 times this amount of error - thus my long wordy request for some mentoring. Am I expecting to much? The goal here is to understand more about what the numbers mean and are they reality. Does this older Receiver have some limitations? Am I looking at the numbers the wrong way? Your comments will be appreciated. This is truely an academic request as my real interest in the GPS unit is to get the date and time to run a radio experiment. The unit will be some 10 to 15 miles away from here, so the transmitter will be just below killing the receiver level hi. 73, Larry, VA3LK --- You are currently subscribed to tacgps as: lyris.tacgps@tapr.org To unsubscribe send a blank email to leave-tacgps-6754G@lists.tapr.org From bounce-tacgps-6754@lists.tapr.org Thu Apr 8 01:54:03 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.9) with SMTP id BAA29876 for ; Thu, 8 Apr 1999 01:54:01 -0500 (CDT) From: Darryl Smith To: "TAPR Special Interest Group" Date: Thu, 08 Apr 1999 17:48:29 +1000 Message-ID: Organization: Quite poor X-Accept-Language: en MIME-Version: 1.0 Subject: [tacgps] Numbers, darned numbers.....

You should be happy with those numbers. I had a GPS-20 on a friends car. He was driving round Sydney, beaconing.

And I have had the GPS move it's position by 50 kM more than once, also whilst mobile... These are single channel units, and I must assume that they are best suited for use on the water where the horizon is much better than in major cities...

It sounds like you are treating the latitude and logitude strings in the NMEA data as simple decimal numbers and averaging them. This isn't going to yield the right numbers in general, though it probably doesn't make a difference in your case. The string "4439.7891" means 44 degrees, 39.7891 minutes. If you want to convert this to decimal degrees (so you *can* do normal arithmetic averaging), you need to take the 39.7891 part, divide by 60, and add it to the 44. Alternately, to convert to decimal minutes, take the 44, multiply by 60, then add the 39.7891. Either way, you have to treat the thing as two separate strings run together. >For this location then the (my word) jitter is say 18 seconds for the Lat >and again 27 seconds for the Long. These look to me to be a little beyond >what I was expecting, for say worst case of about 8 seconds of error. The >real figures are 2 to 3 times this amount of error - thus my long wordy >request for some mentoring. The spec for SA says +- 100 m, 95% of the time. That's about 3.25 seconds of latitude and 4.55 seconds of longitude at your latitude. However, the other 5% of the time it can be larger than that - potentially much larger once in a while. If you discard the 5% of positions that are furthest from the mean position, are the remaining ones within the published limits? If so, you really can't complain. However, your errors do seem larger than what I've see when I had a GPS 20. Also, the quality of the received signal makes a substantial difference in the position accuracy. A good active antenna with an unobstructed view of the sky will generally give yield pretty accurate positions. A poor antenna, giving marginal signal strength for most satellites, or a good antenna positioned where substantial portions of the sky is blocked by obstructions, will cause the receiver to give poorer positions. Weak signals add noise to the position, while if parts of the sky are blocked then geometry will sometimes be poor and errors can get large. >Am I expecting to much? The goal here is to understand more about what the >numbers mean and are they reality. Does this older Receiver have some >limitations? Yes, the GPS-20 is a single-channel multiplexing receiver. I once had one, then later upgraded to the GPS-25. The latter gave more accurate fixes. Even with SA, the 25's ability to track more satellites allows it to produce better solutions most of the time. And with differential GPS corrections, the 25 is considerably more accurate. In an hour of collected data, the differentially-corrected GPS-20 gave positions with a standard deviation of about 4 meters in lat/long. The GPS-25 gave 1.9 m latitude and 1.1 m longitude standard deviations. This suggests to me that the 25 has less receiver noise. (The source of the DGPS corrections is a Canadian Coast Guard station only a few km away). >This is truely an academic request as my real interest in the GPS unit is to >get the date and time to run a radio experiment. The unit will be some 10 >to 15 miles away from here, so the transmitter will be just below killing >the receiver level hi. If you just want the time to the nearest second, it should be fine. If you use the 1 PPS output for microsecond-level timing, the large position errors suggest that the timing might also be off by a couple of microseconds from time to time (ahem). The 25 is apparently a much more stable timing source than the 20 - see previous postings by Tom Clark in this mailing list about timing performance of the 20 and 25.

I am using the Garmin antenna and it does have an amplifier in it. I have not used the motorola antenna so I can't comment on it. The only potential problem I can think of would be if the two antennas are designed for different power supplies. You will either have an antenna that doesn't amplify or you'll burn it up. 73, dan W6LSN Once I free up some more discretionary funds, I'll be buying a Motorola GPS and putting the Garmin in one of the vehicles.

David, Yes, both the Motorola Antenna97 and Garmin GA-27 have amplifiers built in. Both require +5V to power them. Kirk Mentioned: >I bought the Motorola antenna listed on the TAPR for use with the TAPR >DGPSIB/Motorola Oncore VP and it works great. However I tried >connecting it to my Garmin GPS III Plus and the unit doesn't even >recognize that its there: in fact it makes reception worse. This shouldn't happen. Most, if not all, Garmin products send +5VDC up the antenna line to power the amplifiers in the antenna. If there is a DC block (i.e. capacitor) this will cause the amp to not be powered and yield a poorer reception. Or maybe the GPS receiver has a problem sending +5VDC out. Both antennas have the same performance gain wise. The major differences are physical. The Garmin is mag or suction cup mount (you choose and it is interchangable). And the antenna connection is an MCX connector. The Motorola is mag mount only and it has a BNC connector. For many, if you choose to use the Antenna97 with an OEM GPS receiver such as the Oncore or Garmin GPS25, then you will need a MCX to BNC adapter. TAPR sells a RF pigtail ($15.00) that has a MCX connector on one end of RG-174. It's about 18" long. The other end is blank. The idea is that the user decides what they want on the blank end. For example, you can buy a bulkhead BNC connector and mount it on an enclosure. Then the Antenna97 plugs right into it. Another idea is to purchase the GA-27. Cut the cable approximately 6" from the MCX connector. Install a BNC bulkhead to the MCX side, and a BNC to the antenna side. This allows you the flexablity of using a BNC connector which is common on many GPS antennas. Thus you can exchange antennas with friends :-). The bottom line price wise: Antenna97 + RF pigtail = $80.00 (less 10% member discount = $72.00). Garmin GA-27 = $75.00 (less 10% member discount = 67.50). Hope this helps. 73, - Steve, N7HPR n7hpr@tapr.org n7hpr@amsat.org --- You are currently subscribed to tacgps as: lyris.tacgps@tapr.org To unsubscribe send a blank email to leave-tacgps-6754G@lists.tapr.org From bounce-tacgps-6754@lists.tapr.org Sat Apr 10 10:19:37 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.9) with SMTP id KAA15877 for ; Sat, 10 Apr 1999 10:19:36 -0500 (CDT) Message-Id: Date: Sat, 10 Apr 1999 15:18:24 +0000 From: "Dr Thomas A Clark (W3IWI)" Reply-To: "TAPR Special Interest Group" X-Accept-Language: en Mime-Version: 1.0 To: "TAPR Special Interest Group" Subject: [tacgps] Re: Motorola or Garmin Antenna References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio X-Message-Id: <370F6BC0.265F2B10@clark.net> Sender: bounce-tacgps-6754@lists.tapr.org Precedence: bulk Dan Hinz wrote: > I have not used the motorola antenna so I can't comment on it.

Both Motorola and Garmnin have preamps. The both adhere to the de facto industry standard of +5v at ~20 ma power fed thru the coax to power the ~25-30 dB gain MMIC LNA that built into the antenna. Nearly all remote antennas are amplified to deliver a fairly low noise figure despite ~20 dB loss in the small coax. Both should antennas work fine -- the Motorola has become my choice. The Motorola is a bit cheaper from Rick Hambly (http://www.cnssys.com) 73, Tom --- You are currently subscribed to tacgps as: lyris.tacgps@tapr.org To unsubscribe send a blank email to leave-tacgps-6754G@lists.tapr.org From bounce-tacgps-6754@lists.tapr.org Sat Apr 10 10:33:59 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.9) with SMTP id KAA16146 for ; Sat, 10 Apr 1999 10:33:59 -0500 (CDT) Message-Id: Date: Sat, 10 Apr 1999 15:32:37 +0000 From: "Dr Thomas A Clark (W3IWI)" Reply-To: "TAPR Special Interest Group" X-Accept-Language: en Mime-Version: 1.0 To: "TAPR Special Interest Group" Subject: [tacgps] Re: Motorola or Garmin Antenna References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio X-Message-Id: <370F6F15.3A36890C@clark.net> Sender: bounce-tacgps-6754@lists.tapr.org Precedence: bulk Kirk Alexander wrote: > > I bought the Motorola antenna listed on the TAPR for use with the TAPR > DGPSIB/Motorola Oncore VP and it works great.

Odd, because that was not my experience with the Antenna-97. I used it with a Motorola VP Oncore. With the antenna hanging in a rose bush within three feet of my metal roofed house, a very poor site for sky coverage, the Oncore picked up solid lock with 4 satellites. None of my hand held units could do as well in that location. And last time I checked, the branches of a Siberian Rose bush were non metallic. --Ira --- You are currently subscribed to tacgps as: lyris.tacgps@tapr.org To unsubscribe send a blank email to leave-tacgps-6754G@lists.tapr.org From bounce-tacgps-6754@lists.tapr.org Sun Apr 11 18:45:46 1999 Received: from lists.tapr.org (lists.tapr.org [204.17.217.24]) by tapr.org (8.9.3/8.9.3/1.9) with SMTP id SAA22206 for ; Sun, 11 Apr 1999 18:45:45 -0500 (CDT) From: TomR736570@aol.com Message-ID: Date: Sun, 11 Apr 1999 19:44:50 EDT Subject: [tacgps] Re: Motorola or Garmin Antenna To: "TAPR Special Interest Group" MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Reply-To: "TAPR Special Interest Group" List-Unsubscribe: List-Software: Lyris Server version 3.0 List-Subscribe: List-Owner: X-List-Host: Tucson Amateur Packet Radio X-Message-Id: <120ca4bb.24428df2@aol.com> Sender: bounce-tacgps-6754@lists.tapr.org Precedence: bulk Kirk And others.

I understand from the reference to boards that you have a component-level system in mind, speaking to a PC. To which must be added the antenna, power supply, etc. What I have in mind is a complete (second hand) GPS receiver, usable as a stand-alone item, or as a source of PPS for the phase-locking role. By the way, certain of the SABC transmitters are precision offset to reduce interference to viewers in remote locations, and locked to Rhode and Schwarz rubidium standards. In Joburg the ch 13 transmitter is on 247.456.025 MHz, for example. This will give around 1 in 10E-10, or 1 in 10E-11 on a good day. I could phase-lock the oscillator to this in real time, using the error voltage to pull the 10 MHz oscillator, without worrying about long time constants, super-stable crystal ovens, or GPS! But it still requires another receiver, interface board, 10 MHz oscillator, antenna, etc., so maybe the GPS route is going to be cheaper (and more convenient) after all. Do do know of a local source of 10 MHz voltage controlled crystal ovens? What would you do?

Use an ohm meter to ring them out. Cause I have a PicoPacket and the colors verse signals were wrong. You can see the DGPS corrections coming out of the DGPSIB buy connecting it to a computer running a terminal program. This would be a simple and good thing to do to verify that the DGPSIB is working and operating at the baud rate you selected. On the PicoPacket connecting to the DGPSIB, make sure it is operating at the same speed as the DGPSIB. The wiring connections are as follows: Pico DGPSIB ------ -------- 3 3 Diff corrections out of the DGPSIB and into the Pico 5 5 Ground For a remote GPS receiving the corrections the wiring would look like: Pico GPS Receiver ------ -------- 2 ? Diff corrections out of the Pico and into the GPS 5 5 Ground I put a "?" because you need to find the pin that is the INPUT to the GPS receiver.

This year's conference location is just minutes away from the Phoenix Sky Harbor International Airport (PHX). ----- Symposia, Seminars, Banquet In addition to the presentation of papers on Saturday, three symposia/seminars will be held. These sessions are provided to allow those with additional time and interest to make the most of the Digital Communications Conference. For those who may have interest in just one symposium or seminar, registration for the conference is not required to attend these activities. This allows maximum flexibility for those who may want to participate during the Digital Communications Conference, but do not have an entire weekend to devote to the event. The Third APRS National Symposium will be held on Friday and will be moderated by Steve Dimse, K4HG (the developer of javAPRS). It will likely include many APRS software authors, such as Bob Bruninga, WB4APR (the father of APRS), Keith Sproul, WU2Z, Mark Sproul, KB2ICI (the developers of MacAPRS and WinAPRS), Brent Hildebrand, KH2Z (the developer of APRSPLUS), Mike Musick, N0QBF (developer of PocketAPRS), and other nationally-known APRS leaders. Join this group for the afternoon and evening for in-depth discussions and presentations on the current and future status of APRS. This is a unique opportunity to gain insight into this fast- growing digital aspect of amateur operations that combines computers, packet radio, and GPS (Global Positioning System). Starting late Friday afternoon, a half-day technical seminar will be held. In the past this seminar has covered topics such as RF, DSP, Advanced Networking Topologies and other stimulating topics. On Saturday night the DCC Banquet will be held. This year the conference is proud to have Geoff Baehr, N6LXA, Sun Microsystems Chief Network Officer at the banquet to speak. Sun Microsystems has been doing some very exciting things in networking over the years and the talk should be an interesting one. After the banquet there will be time for special interest group gatherings. The Sunday morning seminar will be focused on PIC development, design, and programming. This five-and-a-half hour seminar will focus on the things you need to know now in order to understand and begin to participate in PIC development. PIC processors are becoming very important in various project designs and implementations. This seminar will by presented by the TAPR PIC Development team. ----- Fourth Annual ARRL and TAPR DCC Student Papers Award ARRL and TAPR especially welcome papers from full-time students to compete for the fourth annual student papers award. Two $500 travel awards may be given, one in each of the following categories: a) best technical/theory-oriented paper by a student, and b) best educational or community-oriented application paper by a student. The paper should relate directly to a wireless digital communication topic (see the guidelines for more information). Papers co-authored by educators or telecommunications professionals are also eligible for this award as long as a student is the first author. The deadline for receipt of finished student paper manuscript is July 10, 1999. Please note that this deadline is different from the general conference paper submission date. For full details and paper guidelines contact TAPR or browse to http://www.tapr.org/dcc. ----- Call for Conference Proceeding Papers Anyone interested in digital communications is invited to submit a paper for publication in the Conference Proceedings. Presentation at the conference is not required for publication. The primary purpose of the conference is to communicate ideas and techniques regarding digital communications. Papers written in an informal style are welcome, as well as those written to academic standards. If you know of someone who is doing great things with digital communications, be sure to tell them about this! Papers are due by August 9, 1999, and should be submitted to Maty Weinberg, ARRL, 225 Main Street, Newington, CT 06111, or via e-mail to lweinberg@arrl.org. The paper submission guidelines are available on-line (http://www.tapr.org/dcc). ----- International Co-Host PRUG (Packet Radio User Group of Japan) will be the International co- host for a second year running. PRUG will be hosting an informal social Friday evening before their seminar and symposium is held. Visit http://www.prug.or.jp for more information about the organization. ----- Full information on the conference and hotel information can be obtained by contacting Tucson Amateur Packet Radio, 8987-309 E.
