Zusammenfassung:	A satellite navigation system including a digital controlled reception pattern antenna (DCRPA) subsystem and a global navigation satellite system (GNSS) receiver. The overall system is designed so that all radio frequency (RF) processing and digital sampling are incorporated in the DCRPA subsystem. The RF signal from each element of the DCRPA array is digitized separately. Then the resultant digital samples are combined into a single bit stream which is transmitted to the GNSS receiver. Preferably the GNSS receiver is a software defined radio. The arrangement allows the DCRPA subsystem and the GNSS receiver to be connected with a single coaxial cable. Such an arrangement would allow simple retrofit of CRPA antennas to existing airframe designs as well as simple and inexpensive installations on new aircraft designs.
