Claim:
1. A method for determining an initial transmit power level from a communications device to a satellite, the method comprising: receiving a downlink signal from the satellite via the communications device; determining a strength of the downlink signal computed from knowledge of a receiver gain represented by a first coefficient, the first coefficient based on first historical data, the first historical data including correction data obtained by the communications device after a transition from a power level of an initial open loop transmit power control operation to a power level of a closed loop transmit power control operation; determining the initial transmit power level for the communications device based on the strength of the downlink signal, the first coefficient, and a transmitter gain represented by a second coefficient, the second coefficient based on second historical data, the determining based on a look-up of the first coefficient and the second coefficient from an array of first coefficients and second coefficients that are listed in the array at one or more corresponding power levels.
