NaviGEO

NaviGEO is SpacePNT’s high performance solution designed for launcher upper stages and in-orbit servicing vehicles. It features dual-antenna inputs to provide optimal GNSS visibility across various orbital altitudes, from Low Earth Orbit (LEO) to Geostationary Orbit (GEO), regardless of the vehicle’s attitude. This system offers the highest autonomous positioning and timing precision, thanks to its dual antenna inputs that allow signal reception from two antennas without a combiner, enhancing precision through lever-arm computations and improved C/No reception. NaviGEO boasts a low-cost and compact design, based on a COTS-based “New Space” approach and implementing a radiation tolerant hardware, software, and firmware architecture. It is upgradable and scalable, supporting both passive and active antennas, with in-flight firmware/software upgradability. This unique platform solution is suitable for launchers, LEO, GEO, HEO, and Moon missions, and offers an external LNA as an option. Its highly reliable architecture includes an onboard orbital propagator for improved performance and availability, supports multiple GNSS (GPS, GALILEO) over multiple frequencies, and allows for cold redundancy with two units. Radiation Hardness Assurance is also available as an option.
