1. A system, comprising:
a radar altimeter configured to be coupled to a vehicle, comprising:
a transmitter configured to generate radio frequency (RF) signals, and to provide the RF signals to an antenna configured to radiate the RF signals towards a ground location,
a receiver configured to receive a reflected portion of the RF signals, and
a controller coupled to the transmitter and the receiver, wherein the controller is configured to control the transmitter, to receive the reflected portion of the RF signals, and to determine a height parameter based on the reflected portion of the RF signals; and
a network receiver coupled to the radar altimeter, wherein the network receiver is configured to:
receive network signals corresponding to an off-board telecommunications network;
decode the network signals received by the network receiver to determine at least one signal parameter from the network signals, wherein the at least one signal parameter includes a signal strength of the network signals and timing synchronization information of the network signals including scheduled time periods for downlink and uplink transmissions; and
at least one processor coupled to the network receiver and the controller, wherein the at least one processor is configured to configure operation of the radar altimeter based on the at least one signal parameter from the network signals.
