Global Navigation Satellite Systems Engineering, Policy, and Design
Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.

European Union (EU) member countries are close to adopting a standard for satellite navigation receivers.
The proposed standard covers Satellite Earth Stations and Systems (SESS) as well as GNSS receivers operating in the bands 1164 MHz to 1300 MHz and 1559 MHz to 1610 MHz. Receivers must be able to withstand interference from adjacent bands at the listed levels.

Q: Would you prefer to have more signals or more satellites?
A: This is somewhat of a classic GNSS question, but before getting to the answer, let’s seek some clarity about what is being asked. First, by definition, “more” signals or “more” systems must be referenced against some baseline configuration. This is commonly assumed to be a GPS L1 C/A solution, and this assumption is also used herein.

The Federal Communications Commission is being asked to choose between the immediate benefits of officially improving U.S. satellite navigation receivers and the possibility that, in doing so, it may raise interference levels in a neighboring band or make it harder to develop alternative uses for those adjacent frequencies.

Some of the specific technical issues behind the latest delay for Galileo’s first full operational capability (FOC) satellites have already been reported. The story, as it is told, generally starts with a late navigation payload delivery by British firm Surrey Satellite Technology to the German prime contractor, OHB. Next, OHB ran into issues with the payload and the platform, further stretching out the timeline.
