GPSr comparison - Garmin v LEGO
I took my new GPS unit for a quick test run last week to compare it to my good old faithful Garmin Etrex Vista Cx. I set the NXT+dGPS to log its coordinate every 5 seconds, and the Garmin was left on its defult settings. Both units were positioned in between the driver and front passenger seat of my car. I waited until both units had a satellite fix before I started driving.
Yellow - LEGO NXT+dGPS
Blue - Garmin Etrex Vista Cx
At the start of the journey, the NXT takes an early lead... (click on the image to see it full size)
But at the end, it's the Garmin that finishes strongest.
Nothing particularly conclusive here, but nice to see that the results are comparable!
I live in Tasmania, Australia, and teach Mathematics and Robotics at Claremont College. I also teach students from around Tasmania through my online robotics class, SmartBots. In my spare time, I enjoy hunting for little plastic boxes ("geocaching").
