Hey all! First time user here. I am part of a collegiate rocket team, looking to deploy a paraglider from apogee and have it run a simple waypoint mission to the ground. From my research, PX4 seems like an excellent system to use. However, I have run into a slight (ok major) hiccup. As far as I know, the Pixhawk needs to be hooked to a transmitter on the ground and coded to a switch to “start” the mission. I need the system to be able to start the mission without a transmitter, either via a timer, barometer, light sensor, or something else onboard the paraglider. I also realize that it takes time for the system to get a GPS lock, but that part can be started on the ground. I need JUST the waypoint mission to start at a certain point without a transmitter.
