Our GNSS software solutions support best-in-class high-accuracy positioning by using high quality raw-data, proprietary technology and services based on our own global GNSS reference receiver network. With SpaceStar® technology we deliver improved performance without any additional ground infrastructure.
SpaceStar® precise navigation technology can be applied to a variety of applications, including:
Enhanced Space Situation Awareness
Precise state vector knowledge allows us to optimise collision avoidance manoeuvres, reduce the number of collision warnings, increase mission safety and reduced operational effort.
Precise Thruster optimisation
Real-time delta-V knowledge can be used to measure the performance of on-board thrusters, as well as optimise fuel consumption to perform in-orbit manoeuvres.
Close Proximity Operations and Auto Docking
Applications related to docking or in-orbit servicing require precise orbit knowledge to minimise collision risk. Using sub-decimetre SpaceStar®-enabled GNSS positioning can help reduce dependencies on heavier payloads (such as cameras or radars), while providing enhanced integrity for GNSS-based position and velocity.
Earth Observation applications
Many Earth observation applications, such as GNSS radio-occultation or synthetic-aperture radar (SAR), require precision orbit estimation to process instrument data. On-board precise orbit estimation allows us to perform on-board data processing, thus increasing mission autonomy and scalability.
The error on RF geolocation from space depends heavily on the orbit and clock errors of the LEO constellation performing RF sensing. By leveraging SpaceStar® the accuracy of the RF geolocation on the Earth surface can significantly increase.
