Comme vous le comprendrez en lisant l'info en anglais ci-dessous, Sealaunch lancera fin 2010 une première grappe de 8 satellites sur une orbite terreste dite "medium" (MEO - 8000 kms) pour la compagnie 03b visant à assurer des connexions internet dans les pays où les liaisons filaires ou Wimax sont peu développées, voire difficilement déployables. Un second lancement d'une autre grappe aura lieu ensuite à une date encore non déterminée.
C'est à priori pour les pays pauvres (!) mais peut-être qu'un jour un tel système sera fonctionnel pour nous aussi (une petit antenne dépliable et hop internet sur la plage)...
September 23, 2008 -- Sea Launch Company has signed a launch
services agreement with O3b Networks Limited for up to two launches in
support of their Medium Earth Orbit (MEO) telecommunications satellite
constellation, with the first launch set for late 2010.
Built
by Thales Alenia Space, the O3b Networks satellites will be deployed by
Sea Launch's Zenit-3SL system in groups of eight per launch, to an
equatorial injection orbit of 7,825 kilometers above the Earth. The
satellites, each weighing approximately 700 kg (1,540 lb.), are
designed to provide high-speed, ultra-low-latency Internet Protocol
(IP) connectivity between emerging and developed markets worldwide.
O3b
Networks' new global communications backbone will fundamentally change
the way IP, 3G Cellular and WiMAX networks interconnect. This will
reduce the costs of backhaul for Mobile Operators and Internet Service
Providers, enabling them to provide more cost-effective services in
underserved and emerging markets.
Sea Launch is
developing a new multi-spacecraft dispenser for these missions, which
will accommodate O3b Networks’ specific orbital insertion requirements.
Upon successful sequential deployment, the satellites are expected to have an on-orbit maneuvering lifetime of ten years.
