Service Module configuration
The Service Module (SVM) is a 'box' shaped structure that interfaces with both the launch vehicle and the Payload module. The SVM design is based on the Envisat/SPOT 5.
The SVM provides all the standard service functions:
Attitude and orbit control:
To maintain accurate Earth-pointing during the various operational modes.
To perform orbit acquisition and maintenance. This includes propulsion, for orbit and dedicated manoeuvres, as well as propellant storage.
Electrical power generation through:
- the solar array
- overall distribution
Command and Control
Distribution of on-ground and on-board generated commands, and collection of housekeeping telemetry data for transmission to ground through the S-band link.
Ground Communication using central on-board software for:
- telemetry generation
- telecommand processing
- various application functions like thermal control, on-board surveillance, automatic command sequencing
