The federal government is rumored to be nearing a decision about Ligado Networks’ request to repurpose its satellite frequencies to also support a ground-based telecom network. Those frequencies neighbor the band used by GPS. Testing done both several years ago and more recently has shown such a system could seriously interfere with GPS receivers.

This article focuses on the research project Galileo Online: GO! – which with support from the Federal Ministry for Economic Affairs and Energy (grant number 50NA1510) designs and develops a reliable and high-precision receiver for multi-constellation and dual-frequency GNSS whose suitability and capabilities are tested in railway applications. Project results showcase the advantages of GPS and Galileo if used simultaneously in railway applications.

An independent technical review ordered by the federal government’s top GPS policy body found that there is sufficient data to assess the risk of using frequencies near the GPS band for a ground-based communications network. Existing test results can also be used to set power limits for other similarly located projects, said a panel of technical specialists. Two tests sponsored by Ligado Networks, however, did not meet minimum criteria for inclusion, the panel said.
