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.
