I have been looking at different way of telemetry. I wanted something that could work for a long distance without have to worry about HAM radio licensing.
So far the parts I have:
A cheap generic GPS module from ali express
Adafruit Feather Fona
Hologram Developer iot sim card
Right now it is coded to collect GPS coordinates every 10 seconds and send them to a web service I created. From there I have an app that reads the last know location and draws a google map to direct you to the rocket.
I have only had a change to test it once and it was about to get me within 15 feet of my rocket.
I will post updates as I test more. I plan on adding a baro sensor to capture altitude as well. With Hologram you get 1/Mb free a month and $0.60/Mb after that. Each packet I send is 224 bytes.
Has anyone else every used GPRS for telemetry? Are there any know concerns I should be aware of?
