XTAR-EUR
The XTAR-EUR is a communication satellite developed by Spain and the United States and in order to provide a secure channel over the Indian Ocean. It was originally operated by XTAR and Hisdesat. In year 2020 Hisdesat bought 100% stake on the satellite. Its launch short after the Spainsat is part of an effort to strengthen Spain's communication ties with allied countries around the globe, particularly in maters of national security.
Body
The satellite is based on the Space Systems/Loral LS-1300 model. Consequently, it is shaped like a box with a total weight of 1412 kg. The sides of the box contain two retractable solar panels while the lower base holds the communication module. This module operates on the X band and consists of 12 X-band transponders of 72 MHz broadband each and a 2.4 diameter antenna. The system allows both RHCP and LHCP polarization while covering an area of 6,3095 m2 RCS. Additional systems provide 3-axis inflight stability.Launch
The satellite was officially launched the 12th of February 2005 at 21:03 UT on board an Ariane-5 ECA rocket from the Guyana Space Center.Its orbit is geostationary 29º East, around 35,800 km high with 0º of inclination, a period of 1,436.1 minutes and a semi-major axis of 42,164 km.
During its operation life, the XTAR-EUR is being monitored from Arganda del Rey and Maspalomas Station. While the operating companies are based on Washington, D.C., Madrid and Palo Alto.
It is expected that the satellite will achieve an operational life exceeding 15 years until its planned decommission in 2023.
