what I find interesting about that is the info stream doesn’t contain time and gps location along with it. why wouldn’t it these days?
anyone know if it’s possible for gps chips to receive satellite signals while the engines are running? or would they interfere?
I would expect GPS lat/lon and GMT to be included in the engine data for identification purposes. An aircraft has dozens of GPS’s, it is just a chip, and could use an internal antenna. The additional payload of lat/lon and GMT is 12 bytes of data. OTOH, I would expect the engine data to be routed elsewhere to an external antenna. (GPS is receiving, engine data means higher-power transmitting)
GPS receivers need an antenna that has a clear view of the satellites.
If you’ve got a hand-held GPS receiver, try using it inside a building, away from the windows.
