Galileo HAS Receiver for Precise Orbit Determination for LEO and low MEO

The Galileo High Accuracy Service (HAS) offers an opportunity to enhance onboard real-time precise orbit determination (POD) and navigation payload design for low Earth orbit (LEO) and low medium Earth orbit (MEO) satellites. Spaceopal, in collaboration with the German Aerospace Center, is developing a novel Galileo HAS receiver tailored for real-time POD and LEO/ low MEO navigation payloads. This receiver provides autonomous onboard knowledge of satellite’s orbit with centimeter accuracy in real-time enabling cost-efficient operations, better collision prediction, accurate payload pointing among other benefits. Additionally, the POD receiver facilitates time synchronization for LEO/ low MEO PNT navigation payloads.
