PolaRx5 satnav receiver for geoscience, developed by Belgium's Septentrio with ESA support. The receiver uses signals from multiple satnav constellations for maximum precision. Designed for years of continuous use, the PolaRx5 has a power consumption of just 3 W (half the previous value) with large-scale internal and external data logging with low-bandwidth communication to return findings – essential features for remote scientific monitoring. It can also be used for atmospheric monitoring, tracking propagation patterns of satnav signals.
