Quick Question. I am planning on using the Electron for a near space balloon project in my class. I want to transmit position constantly up to a point. I know it will stop getting GSM signal at some point, but would like a little more details of what to expect in terms of altitude that the cellular antennas can reach. Also What kind of antenna do you recommend I use and if theres any other tips you can provide I would be grateful.
Also, are there any firmware design practices in terms of knowing when theres no signal and attempted reconnects?
As a fall back, do you have any recommendations on a long range, low weight Data-Link transmitter we can use?
I am looking at a couple of options from DIGI. One is a 1 watt transceiver but it is expensive. My bet will be something in the middle with very good tuned high gain antennas. Any help would be appreciated on where to get this kind of antennas for this modules.. This is what we have found so far:
