1. A satellite communication system, comprising:
a multi-beam antenna configured to receive different satellite transmissions from different directions simultaneously via different beams; and
one or more processors configured to:
direct the multi-beam antenna to track three or more non-global navigation satellite system (GNSS) satellites whose transmissions are signals lacking location and time data;
determine time based on one or more of the three or more non-GNSS satellites; and
determine a location of the satellite communication system based on location information determined from the signals from each of at least three of the three or more non-GNSS satellites.
