About the calculations

Pass times, azimuth, elevation, range, footprint, and Doppler are calculated in the browser from the current TLE for the selected spacecraft and the NWSMS station location. Predicted frequencies are guidance for receiver tuning; published satellite operating information remains authoritative.
