Leoterra LLC, a low-Earth orbit (LEO) satellite communications company, and Terrestar Networks Inc., a subsidiary of Motient Corp., announced Dec. 5 they will perform a joint feasibility study toward providing interoperable, advanced global mobile broadband communication services from their respective LEO and geostationary-based satellite networks.

The interoperability of the satellite communication systems would provide global mobile broadband communications to support public safety and emergency providers while offering rural connectivity and wholesale wireless network extension services to retail operators, the companies said.

Leoterra and Terrestar have been working to develop a joint strategy to provide previously unavailable products and services over both networks using a common terminal or handset device. The companies have asked Surrey Satellite Technology Ltd., Leoterra’s satellite design partner, to study the advanced services.
