Satellite Fleet

Key Highlights

  • ABS-4/Mobisat-1 is a geostationary mobile multimedia satellite
  • It is equipped with S-band and Ku-band coverage over the GCC countries
  • The satellite provides direct broadcast of digital audio/video content to mobile users via two high-powered cross polarized Ku/S band beams: West Beam and East Beam
  • It is also capable of distributing the digital data content to terrestrial repeater networks within the beam via two Ku/Ku-band beams
  • ABS-4/Mobisat-1 is a Space Systems/Loral FS1300 satellite
