My original intention for my PIC16F88 Delorme Tripmate GPS Logger and GPS Logger with Time and Speed was to log my runs around Lafayette and West Lafayette. However, I’ve found that the weight of the GPS makes it a real pain to lug it around. Running around with a weight bouncing around in my backpack is no fun. Now that it has gotten warmer and the sun is shining ’til 9 PM (really more like 9:30 PM), I’ve been biking quite a bit. The lower impact nature of bike riding makes it much easier to carry the Tripmate GPS receiver. So I took went out this afternoon for a ride to see how it performs:
And the ride did not turn out too bad! (Click the image above to see a better view of the route, outlined in yellow.) There are some problems with the logging, but this can be attributed to the quality of the fix (most likely 2-D for most of the ride) and the tendency for the GPS to loose its fix when the sky was occluded. See the upper right of the path where I went biking through the woods and you can see that it lost the fix from the time I entered the woods to the time I left them.
