anyone ever attach a gps enabled node to a drone and try an experimental ttnmapper flight to check gateway visibility?
I believe people have skipped that and are on to High Altitude Ballooning …
I have done it the other way around, with plain LoRa, checked visibility of nodes on the ground when the receiver is on board an RC plane.
I thought about it but have not done it.
But as you already wrote the measurement should be marked as “experimental”.
An experiment is a way to keep unrealistic coverage measurements away from the main map. Experiments should be used when coverage is mapped from aeroplanes, balloons or any similar unrealistic altitudes.
As Lora is very line-of-sight dependant, you’re not really generating useful information as the antenna on the drone is not going to be representative real world usage.
The TTNMapper project recommends antennas are at ground level for the data to be useful.
