About
The CELESTE GNSS receiver is a compact and robust solution for small satellite navigation, supporting multiple global navigation satellite systems including GPS (L1), Galileo (E1), BeiDou (B1), and GLONASS (G1). It is designed to operate in the harsh space environment with an operating temperature range of -40°C to +85°C. The receiver provides high time accuracy of 5 ns and supports update rates up to 25 Hz. Its small dimensions and low mass make it suitable for CubeSats and other small satellite platforms. The CELESTE GNSS can be combined with an On-Board Computer (OBC) to form a complete GNSS + CDHS system, with a total size potentially less than 0.2U. The product comes with an aluminium cover, an extension board for testing and development, a debug cable, an Interface Control Document, and 1 hour of engineering support. It is ITAR-free, facilitating international deployment. The typical lead time for orders is 4-5 months.
