ASTROFEIN GPS receiver unit- ARGO

GPS receiver unit


• 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.
