ABSTRACT:
A communication network (10) includes a number of satellites (12) traveling in low earth orbits (14). The satellites (12) broadcast data which identify particular cells (34) within which communication may take place and geographic locations for the cells (34). A radio unit (26) located near the earth's surface receives these broadcast data and calculates a satellite position relative to the radio unit (26). Based upon this position, the radio unit (26) predicts when target satellites (12) will reach their maximum elevation angles relative to the radio unit (26) and the future times at which these maximum elevation angles will be reached. These predictions are then presented to a user of the radio unit (26).
