ASTROFEIN GPS receiver unit- ARGO
Features:
• Configurable redundancy of dual receiver assembly
• Improved solution availability by dual independent passive receive antenna system with passive combination of RF signals
• Equipped with inrush current limitation and voltage/current monitoring
• FDIR capability for timely reaction to system failures
• Navigation firmware and tracking channels optimized to LEO missions
• Receiver warm startup mode to enable rapid time to first positioning fix
ARGO-L1 consists of a receiver unit box and accompanying LNAs and antennas. The box can be supplied in two possible mounting configurations.
