Globalstar GSP-1600 Engineering Mode - Handoffs & SNR

This video is of a Globalstar GSP-1600 in satellite mode. I place a call to a long recording then put the phone into engineering / debug / field test mode and show handoffs between spot beams and satellites as they traverse the sky above my location. The GSP-1600 has a three-fingered CDMA rake receiver, meaning that it can receive and utilize up to three signals simultaneously. Each row on this screen shows the status of a single rake finger. The fields, from left to right, are [finger status] [satellite ID] [spot beam ID] [signal-to-(noise+interference) ratio]. I am not sure what each of the status codes means, but I believe that &stands for active. Each Globalstar satellite transmits 16 separate signals (spot beams), each aimed in a different direction toward the earth. The spot beam(s) visible in a given location from a given satellite vary as the satellite moves across the horizon, and calls hand off between spot beams in much the same manner as they hand off between satellites.
