| Spacecraft Configuration |
Description and Approximate Capacity
|
| Spacecraft |
- Geo-stationary satellite with Bent Pipe payload configuration
(no on-board processing to avoid the obsolescence of processing
technology which develops at a remarkable speed, no inter-satellite
link)
- 12 years life
- 15 kW power
|
| Orbital Slot |
- Located at 120° East
- Additional satellite for co-location or different slot
in the future
|
| Total Digital Bandwidth Capacity |
- 45 Gbps of Spot Beam aggregate capacity at 75-120 cm.
Dish
- Equivalent to 1,000+ Transponders of 36 MHz of conventional
coding and modulation
|
