Thales has developed TopStar Galileo core modules in two standardzed, easy-to-integrate versions.
The small-form-factor Galileo OS (Open Service) or PRS (Public Regulated Service) sensors are designed to enhanced GNSS receivers and resilient multi-sensor navigation systems, ensuring safer and more reliable satellite-based navigation.
The Galileo PRS core module integrates a certified, single-chip, application-specific integrated circuit (ASIC) security module that incorporates all the necessary Galileo PRS security and navigation functions. It provides dual-frequency (E1/E6) iono-free Galileo PRS positioning, velocity and timing services. It also provides pseudorange and delta pseudorange raw data, along with GPS C/A (coarse acquisition).
The low-SWaP (size, weight and power) digital solution has been designed to work with any European GNSS receiver manufacturer seeking a standardized, easy-to-integrate Galileo module with which to develop their own GNSS receivers.
The modules can meet the requirements of a wide range of applications for manned or unmanned vehicles, combat aircraft, helicopters, high-dynamic missiles, and the navy. Their small form factor also makes them suitable for platforms with size constraints, such as ground vehicles, small drones and guided munitions.
The modules feature standardized interfaces, enabling the Galileo PRS function to be easily integrated into the host system. Furthermore, the TopStar Galileo core module can be embedded with minimum impact by using the analog RF front end of the host receiver.
The Galileo OS core module version enables the early integration of Galileo functionalities into the host system, as well as export to countries not authorized to use PRS. The PRS core module version provides an easy upgrade to Public Regulated Service capability, offering greater resilience against jamming and crucial protection against spoofing.
