[time-nuts] Computing GPS Distance Error in Time

Hi Mark,
What I was hoping for was some canned software that will plot position on the display until told to clear it so I can get a visual. I've tried foxtrotgps, but it clears its screen at any and every opportunity, so barring getting into the code that's not going to work. But I can capture the position data from my Adafruit and add it to the plot I'm already doing for timing. So that will work.
thanks,
bob

>I'm not using any special surveying software, just some code that I wrote. The controller box and remote box both have GPS units in them. The controller periodically requests the remote unit's position and just calculates the vector distance/bearing between the two units. The application was intended to work with the boxes spaced 50-5000 feet apart. I was rather surprised how well they worked very close together. The next step is to add a magnetic compass module to the controller box so that it can draw a map of the remote units in relation to the orientation of the controller box.
