Boeing demonstrates digital GPS navigation signals
Boeing has successfully demonstrated a digital version of GPS III navigation signals, a breakthrough that could contribute to significantly modernising the service.
The company said the development overcomes the limitations of current GPS analog payloads in combining multiple signals and accommodating future requirements. It also has fewer components, weighs and costs less, is simpler to integrate and test, and is able to incorporate future signals.
Boeing is developing the digital waveform generator in support of a US Air Force solicitation for GPS III alternate sources. The demonstration validated that the basic GPS signals can be generated digitally in different code combinations with variable power levels and meet stringent signal requirements.
