GMV , the world's number-one independent supplier of telecommunication satellite control centers and responsible for designing, developing, validating, and implementing the control center and user services included in the ground segment of the PAZ satellite, has signed a new contract with INTA (Instituto Nacional de Tecnica Aeroespacial) for the corrective maintenance of the main elements of its ground segment.

The Spanish Paz satellite, with an estimated useful life of seven years, is a dual-use (civil/military) Earth observation satellite in orbit at an altitude of 514 kilometers over the poles and designed for surveillance applications, high-resolution mapping, border control, tactical support in foreign missions, crisis and risk management, natural disaster assessment, environmental control, and maritime environment monitoring.

This satellite is part of the National Earth Observation Program (PNOT) created by the Ministry of Defense and the then Ministry of Industry, Commerce and Tourism of Spain in 2007. Launched in 2018, it brought Spain into the space technology orbit and had GMV as supplier of the mission control center, including all aspects of platform planning and image acquisition, orbital control and satellite pointing and management and monitoring of onboard equipment and communications. GMV was also supplier of the user management and radar image distribution system.

The recently signed new contract, which covers the 2022-2023 period, includes corrective maintenance of the following systems:

+ MCS (Mission Control System): subsystem responsible for communicating with the satellite, processing telemetry indicating the satellite's health and performance and establishing the uplink through control TCs.

+ FDS (Flight Dynamics System): subsystem in charge of orbit determination, generation of platform and orbit events, calculation of flight time delays and dissemination of orbital products, among other functions.

+ MPF (Mission Planning Facility): system responsible for the planning of all platform and instrument activities programmed by users and operators of the other subsystems.

+ GFTS (Generic File Transfer System): infrastructure elements common to the entire control center, which is responsible for distributing files between components of the control center to external elements.

+ MUS (Master User Services): responsible for receiving defense or civilian requests, translating them into satellite and ground segment parameters, and creating and validating a feasible program containing all the required samples.

Russia's invasion of Ukraine hit the space industry harder Wednesday after Roscosmos, the Russian space agency, said it would hold up the launch of satellites for a company with British ownership. OneWeb, a communications satellite company partly owned by the British government, intended to launch 36 satellites Friday on a Russian Soyuz rocket. But Roscosmos issued a statement Tuesday saying the launch was in doubt. "Roscosmos demands guarantees OneWeb satellites not to be used [sic] for ... read more
