Intelsat 901

Intelsat 901 (IS-901) was the first of 9 new Intelsat satellites launched in June 2001 at 342°E, providing Ku-band spot beam coverage for Europe, as well as C-band coverage for the Atlantic Ocean region, and provides features such as selectable split uplink for SNG, tailored for increased communications demands such as DTH and Internet.

Satellite

• Increased power – IS-901 is designed to provide up to 5 dB for downlink e.i.r.p., and up to 1.8 dB for G/T over the IS-VII satellites.
• Increased Capacity – With over 72 C-band 36 MHz equivalent unit transponders, IS-901 provides a significant increase in capacity over the previous satellite at 342°E.
• Improved Coverage – IS-901 provides significantly expanded zone coverage. The Ku-band spot beams also include more area within each zone.

Specifications

• Total Transponders: Ku-Band: up to 22 (in equiv. 36 MHz units)
• Polarization: Ku-Band: Linear - Horizontal or Vertical
• Uplink Frequency: Ku-Band: 14.00 to 14.50 GHz
• Downlink Frequency: Ku-Band: 10.95 to 11.20 GHz and 11.45 to 11.70 GHz
• G/T (Ku-Band) (Beam Peak): Spot 1: up to +9.0 dB/K, Spot 2: up to +9.0 dB/K
• SFD Range (Beam Edge): Ku-Band: -87.0 to -69.0 dBW/m²
