Revision as of 18:37, 30 April 2006
My interest is in learning how to do as much as possible for the least cost.
I have a Garmin eMap and a Garmin GPS 25-LVC module,
and Trimble Ace II and Trimble Lassen SQ modules.
I recently got a Magnavox GPS reference station.
For hobbyists probably the best place to turn is [Spark Fun Electronics], they have a bunch of other modules that I don't list here yet.
Garmin
| Model | Accuracy | Channels | Price | Comments |
|---|---|---|---|---|
| eMap | 15m/2m | 12 | $200 or so | Handheld, accepts RTCM for DGPS. Apparently a bad choice for Rinex software |
| GPS 10 | 15m/3m WAAS | 12 | $250 | bluetooth module |
| GPS 15 | 15m | 12 | bare module | |
| GPS 16 LVS, 16 HVS, 16A 3.3-6V / 6-40V / 8-40 V |
15m / <3m WAAS / 3-5 USCG RTCM | 12 channel | 2 serial ports, deck mount | |
| GPS 17 | $200 | basically the same as a GPS 16 but in a white, pole mount case | ||
| GPS 18 | 15m / 3m WAAS | 12 | $130 | CMOS serial or RS232 or USB hockey puck |
| GPS 25-LVC (3.6-6V), -LVS(3.6-6V RS232), -HVS(6-40V RS232) | 15m / 5m DGPS | ? | bare module; capable of raw data output (pseudorange and phase) | |
| GPS 35 / 36 | 15m / 5m DGPS | ? | 35 = mouse style, 36 = pole mount |
The GPS 17 is designed for marine applications but is often pressed into service in backpack style data collectors.
Trimble

ToppTec -- purveyors of Trimble OEM modules
Delorme
Consumer grade; Earthmates are WAAS enabled but the older Tripmates are cheap on eBay if you just need a NMEA GPS source.
| Model | Accuracy | Channels | Price | Comments |
|---|---|---|---|---|
| Tripmate | 15m? | 12 | $20-30 on eBay | rs232 (discontinued) |
| Earthmate | WAAS | 12 | $100 | USB |
| Blue logger | WAAS | 12 | $150 | bluetooth enabled |
