I am into amateur rocketry. What I am working on is producing a payload with onboard GPS that will transmit position/altitude data (or all NMEA data) back to a mobile base station 3 miles away, allowing the rocket to be located.
The Motorola Oncore GT Plus embedded GPS receiver ( http://www.synergy-gps.com/bgt.pdf
) looks like a good option to me. My problem is transmitting its serial TTL NMEA output. What should I use? Should I be looking at something like this: http://www.orbitcoms.com/Wireless_modules/FM_Wireless_Transmitters_150MHz.htm
Am I able to simply broadcast this data and read it at the base station, or will the link need to be 2-way?
If you are wondering about what other equipment I have, the answer is none... other than a simple Uniden scanner. Thanks for any help anyone may be able to give, and Merry Christmas.
