Has anyone tried using a pair of cell phones as a data link to onboard telemetry???
For example: connecting the output of a GPS receiver to the onboard cell phone using a RS232-to-phone cable and the other phone connected to a laptop. You could even establish a 2 way session by including a micro controller onboard.
Of course this assumes you can make a phone call...... (How about Black Rock??)
