John-Paul Hemingway, SES Networks CEO, argues that low Earth orbit systems will face latency challenges similar to geostationary satellites because closer proximity results in smaller coverage areas requiring multiple hops for long-distance communications.
Arianespace will use a Soyuz rocket on 2019-04-04 to launch four O3b satellites for SES, expanding the medium Earth orbit O3b system to 20 satellites.
In a 2019-02-15 letter, Intelsat and SES supported allowing new users in the uplink band but warned that the large size of C‑band beams and the 36,000‑kilometer distance to geostationary satellites make harmful signal interference a high risk.
SES operates 16 O3b broadband satellites in medium Earth orbit and has four more launching on an Arianespace Soyuz 2019-03 plus another seven under construction by Boeing.
The proposed C-band spectrum sale could generate $40,000,000,000 for Intelsat, SES, Eutelsat, and Telesat.
Martin Halliwell has worked at SES since 1987.
Isotropic Systems will perform over-the-air testing with fleet operators Inmarsat and SES 2019.
Isotropic Systems’ first user terminals will be designed for Ka-band to serve partners SES, Inmarsat, and Avanti.
GeoCarb is slated to fly in 2022 as a hosted payload on an SES Government Solutions communications satellite.
SES is developing the O3b mPOWER system that Boeing is building for a 2021 launch, representing Ka-band competition in the region.
Eutelsat has 37 geostationary satellites and Telesat has 17 geostationary satellites, and the two smaller C-Band Alliance members would use capacity on Intelsat and SES satellites to cover for their lost capacity.
Intelsat and SES are the two largest members of the C-Band Alliance with around 50 geostationary satellites each.
The C-Band Alliance’s plan includes new satellites that would enable Intelsat and SES to operate approximately the same amount of capacity while using only 300 MHz of spectrum instead of 500 MHz.
SES closed a €400 million loan that keeps the company fully funded through 2020.
On 2018-12-03, NSSLGlobal acquired the assets and activities of Station 711, a division of SES subsidiary MX1.
Panasonic Avionics has customized Ku-band payloads on satellites operated by Intelsat, SES, and Eutelsat and has another Ku-band payload under construction on Apsatcom’s Apstar-6D satellite that is scheduled to launch next year.
GovSat-1 is a satellite operated by Luxembourg with fleet operator SES.
Comsys senior consultant Susan Bull identified O3b customers as paying $250,000 for O3b antenna systems in some cases.
SES acquired O3b in 2016.
SES is working with Alcan Systems, Isotropic Systems, and Viasat to build flat or low-profile electronically steered antennas for its O3b mPower satellite system.
