Abstract
A method for facilitating real time tracking of an airborne asset via downlink of GPS signals that are usable for determining asset location information from the asset to a ground station may include receiving a first GPS signal and a second GPS signal at a device disposed on the airborne asset and combining the first and second GPS signals to form combined signal responsive to filtration and amplification of the first and second GPS signals. The method may further include employing an overlay analog translation to convert the combined signal into a composite signal at a different frequency than the combined signal, generating a pilot carrier frequency for association with the composite signal, and amplifying the composite signal prior to transmission via the downlink from the airborne asset to the ground station. The pilot carrier frequency and amplitude may be adjustable.
