SpaceNav
The SpaceNav Receiver for Space Applications
Features:
	Radiation Tolerant
	Fully Dual-Redundant
	Four Antennas
	Automatic Error Detection and Correction
	Accurate 1PPS output
The SpaceNav is a state-of-the-art GPS receiver for satellite applications. It is a fully dual redundant, radiation tolerated, 12-channel L1 C/A code receiver. SpaceNav provides precise orbit determination and precise timing for LEO satellites host vehicles. The system includes a special orbital filter algorithm that provides navigation aiding data, and also smoothes the GPS navigation solution to provide the host spacecraft with a more accurate navigation solution. The SpaceNav includes Error Detection and Correction (EDAC) mechanism that enables an automatic detection and correction of SEU events, that allows the SpaceNav to continue functioning in space.
