Global Navigation Satellite Systems Engineering, Policy, and Design
A: While GPS satellite faults have always been infrequent, they have become rarer in the past decade due to the maturity of the GPS constellation and its Operational Control Segment (OCS). Lessons learned from past GPS satellite failures have also aided the development of newer GNSS constellations such as the European Galileo.

The prototype, consisting of a single Tx-Rx communication link, was tested in indoor-to-indoor, outdoor-to-outdoor and outdoor-to-indoor communication scenarios and in both static and dynamic conditions. The outdoor-to-indoor results indicate that, with further development, the Civilian and Assets Recovery System (CARS) is a promising navigation and positioning technology.

A 4D extension of complex numbers, bicomplex numbers allow for a compact representation of GNSS meta-signals with components from two different frequencies. Acquisition and tracking algorithms are obtained from the bicomplex signal representation, giving it potential for effective dual-frequency GNSS signal processing.
