March 2018 - LEO/MEO Satellites Poised to Make a Mark in Military Sector | Via Satellite
"Satellites in LEO and MEO soon will be here to stay thanks to companies like LeoSat, OneWeb, and SES-owned O3b. The question is whether they also can go beyond meeting the needs of commercial and consumer users to also serving the needs of a dispersed, increasingly mobile military. Via Satellite talks to leading LEO and MEO industry figures to see how they envision their constellations supporting military missions globally in a fast-evolving threat environment."

"The United States Defense Information Systems Agency’s (DISA) recent Request for Information (RFI) calling for a low-latency satellite connectivity solution underscores the government’s openness for considering new non-Geosynchronous Earth Orbit (GEO) solutions. And that cooperative posture also has been illustrated during the Air Force’s wideband Analysis of Alternatives (AoA) exercise to define the future space architecture, where several LEO and MEO companies put forth their recommendations."

"LeoSat is on schedule to launch two demonstration satellites in the second half of 2019. Launch of the production satellites will begin in late 2020 and the constellation should be complete by 2022." LeoSat's Abad: “We are not looking to bring broadband down to every single person in the world. We want to provide carrier-grade telecommunications services via space.”

"Both LeoSat and OneWeb have received high-profile funding — SKY Perfect JSAT became an anchor investor in LeoSat in May, while OneWeb received $1 billion from Japan’s SoftBank last December, making it a 20 percent equity owner. OneWeb also has partnered with Airbus on its new high-volume production facility in Exploration Park, Florida."

“What needs to change is the ground infrastructure — you can’t build a LEO constellation realistically with two parabolic antennas and expect to reach the scale and volume that these providers talk about,” says Brad Grady, senior analyst in Northern Sky Research’s (NSR)

"NSR estimates that the defense sector will require about 14 gigabits per second of non-GEO HTS capacity demand by 2025, representing an 18 percent annual growth rate from 2015."

“Everyone has figured out that the critical point in launching these new constellations is the antenna system. You can’t have a successful non-GEO network without a very agile, very capable antenna technology,” says David Helfgott, CEO of Phasor, one of a handful of antenna technology providers who will plan to offer Commercial-Off-the-Shelf (COTS) antenna solutions for these up-and-coming constellations in the next 12 to 36 months.
