Data Handling and Telecommunications
This sub-system had the following tasks:
- Interim storage data from the experiment
- Transmission of experiment, attitude measurement system and satellite status to Earth
- Transmission of ground commands to the sub-systems concerned
- Support for satellite orbit tracking
The total buffer to store data was 8 kilobits. The data was then transmitted to Earth at a bit rate of 160 bits per second. A clock was also placed on board to create a time stamp on each dataset being transmitted. The antennas for transmission and reception were composed of four rods at a length of 54.3 cm each.
