The Brexit of the United Kingdom from the European Union means limited access to the Galileo system of the European Global Navigation Satellite System (GNSS); without access to the safe and encrypted signal used for security and government purposes, restricted to members of the European Union (EU). The United Kingdom may, as a matter of urgency, launch a payload on a national military communications satellite to provide navigation overlay services for the territory of the United Kingdom, surrounding waters and neighboring allies to meet the requirements of: defense systems, aviation, maritime requirements and the effectiveness of emergency location services. As a navigation overlay service (NOS) on a host national geostationary satellite using GNSS, in particular GPS and Galileo as an alternative to the Galileo PRS, the United Kingdom will deploy a low-cost Satellite-Based Augmentation System (SBAS) as a navigation overlay service (NOS) on a host national geostationary satellite using GNSS, in particular GPS and Galileo as an alternative to the Galileo PRS. This paper describes the design of a navigation overlay service system as a host payload on a national satellite and the required supporting ground.
