Arianespace — OHO, Another Launch For Arianespace

OverHorizon has selected Arianespaace to launch into orbit their OHO-1 satellite due to a number of criteria that included launch capacity, flexibility, as well as a track record of reliability. Speaking at a formal contract signing ceremony during the Satellite 2010 conference in Maryland, OverHorizon CEO Per Wahlberg said the company conducted a "very rigorous" process that led to Arianespace's selection to launch the OHO-1 satellite in mid-2012.

OHO-1 is to be produced jointly by Orbital Sciences Corporation and Thales Alenia Space. Orbital will supply the Star 2.3 satellite bus, which will have a liftoff mass of approximately 3,200 kg. with its payload provided by Thales Alenia Space. Arianespace can orbit this type of satellite from French Guiana either aboard a heavy-lift Ariane 5 (in a dual-payload configuration along with a larger telecommunications spacecraft), or on a medium-lift Soyuz. OverHorizon's goal is to provide a cost-effective combination of the mobility and ease of mobile satellite telephony with broadband services that offer the throughput and real-time capability of traditional fixed satellite communications. OHO-1 will use the latest in space qualified hardware, including on-board processing (OBP), routing and signal regeneration, and steerable spot beams, which will enable the company to meet users' needs for high data-rate, low-profile mobile communications.
