There’s a magnificent constellation of spacecraft in orbit around Earth right now, many sending useful data back down to the surface in the clear, ready to be exploited. Trouble is, it often takes ...

I'm trying to figure out the necessary azimuth and elevation angles for an antenna located at 42 degrees, 06 minutes N lat, 76 degrees, 13 minutes W long, pointing towards a geosynchonous satellite at ...

The Microwave Landing System provides precision navigation guidance for exact alignment and descent of aircraft on approach to a runway. It provides azimuth, elevation, and distance. Both lateral and ...

More satellites, more constellations, more multi-frequency receivers — they all drive greater achievable accuracy. But they also raise the requirements on GNSS antennas because of the stronger impact ...
