The Intelsat VIII-VIII/A series has been designed to meet the needs of Intelsat users
throughout the system for improved C-band coverage and service. These spacecraft will
incorporate six-fold C-band frequency reuse, two-fold frequency reuse of expanded C-band
capacity, and the highest C-band power level ever for an Intelsat satellite. Consequently,
Intelsat VIII will provide significantly more C-band capacity for public switched
telephony and Intelsat Business Service, better quality for video services, and encourage
new international VSAT applications.
Other salient features of Intelsat VIII satellites include:
- Two independently steerable Ku-band spot beams which can be pointed anywhere on the
surface of the earth that is visible from the spacecraft in geosynchronous orbit.
- Interconnected operation between C- and Ku-bands.
- Expanded SNG (satellite news gathering) service provided by the capability to connect
spot beams to global beams, including a return path for small Ku-band transportable SNG
stations for voice/data communications.
This deployment of Intelsat 805 was originally scheduled to use a Chinese CZ-3B rocket.
However, Intelsat bailed out of that plan after losing one of its satellites in a 1996
catastrophic launch explosion of a CZ-3B booster.
In January 2020 Intelsat 805 was put into a graveyard orbit and was passivated.
