For hobbyists probably the best place to get the bare modules is [[http://www.SparkFun.com/ Spark Fun Electronics]], they have a bunch of other modules that I don't list here yet.

Latest revision as of 19:42, 27 October 2018

This page has notes on GPS receivers that I am interested in. I own a few of them and list a few others for comparison purposes.

I list both receivers integrated into systems like the Garmin eMap handheld and modules such as the Trimble Lassen SQ.

You can get the bare modules or you can use modules that have been built up into GPS hockey pucks. (Some people call them GPS mice.) For example, you can get a Garmin 25 module and wire it directly to the low voltage serial port on a PIC processor or you can get a Garmin GPS-18 hockey puck and plug it into a USB port.

For hobbyists probably the best place to get the bare modules is Spark Fun Electronics, they have a bunch of other modules that I don't list here yet.

I got the modules I have currently on eBay.

Since I originally wrote this page I have obtained an Emtac BT-338 from Tigerdirect for about $50 and a Wintec WBT-100, $95 from Semson. Both of these have bluetooth. The Wintec has WAAS, a compass, bluetooth, and USB.

Semson and GPScity are my favorite places to shop for GPS gear. GPScity has RAM mounts.

I have gotten interesting out-of-date stuff like Trimble development boards on eBay.
