Abstract
Broadband satellite terminals are described that allow for automatic adjustment to a gain of an antenna control unit to ensure a power level of a signal received from an antenna is within the required input power level range of the modem. The gain can be adjusted dynamically as needed to account for changes to the modem utilized by the terminal, changes to the satellite, and other factors.
Claims18
A satellite broadband terminal installed within a vehicle, comprising:
- a networking data unit comprising an antenna control unit (ACU), and configured to receive a signal from an antenna of the vehicle;
- a radio frequency unit comprising an amplifier;
- and
- a modem manager configured to receive a first modem having a first required input power level range;
- wherein the modem manager, networking data unit and radio frequency unit are communicatively coupled;
- wherein the modem manager is configured to analyze the signal received from the antenna and automatically calculates an adjustment to a gain of the ACU if the power level of the signal is outside of the first required input power level range;
- and
- wherein the modem manager resets the gain of the ACU based on the calculated adjustment such that the power level of the signal is within the first required input power level range.
A method for maintaining a power level of a received satellite signal in a broadband satellite terminal within a predefined power level range using a computing device including at least one processor, the method comprising:
- receiving a signal from an antenna of a satellite via an antenna control unit (ACU) of the broadband satellite terminal;
- analyzing a power level of the received signal by comparing the power level with a required input power level range of a modem disposed to receive the signal;
- if the power level of the signal is partially or fully outside of the required input power level range, (i) calculating an adjustment to a gain of the ACU and (ii) automatically setting the gain of the ACU to a new value based on the calculated adjustment.
