A method of predicting cell-to-cell hand-offs of mobile subscribers for a satellite cellular communications system. Each satellite of a constellation projects a number of beams or cells upon the earth for communication with mobile subscribers. The satellite transfers (hand-offs) communications links from cell to cell as the satellite moves over the mobile subscriber. Since the movement of the satellite is stabilized in three directions, the projection of the beams or cells follows a predictable path across the face of the earth. Each satellite moves across the earth in one direction. Once a subscriber is located within one cell, the next cell to which the mobile subscriber is handed-off may be determined from the geographic position. For mobile users which are close to boundaries between cells, additional position location may be determined by the calculation of bit error rates. The results of these bit error rate measurements then indicate the identity of the cell which is to receive the hand-off of the mobile user.
