Satellite Olympus

5 avril 2017 par maty185

Olympus carried four separate payloads, a two channel high power direct broadcasting payload operating at 18/12 GHz, a four channel 12/14 GHz Specialized Services Payload, a 20/30 GHz payload for advanced communications experiments, and a 12/20/30 GHz beacon package for propagation experiments.

The Ka band (20/30 GHz) transponders have been exploited extensively by numerous organisations to demonstrate the use of small terminal networks and for video conferencing and satellite news gathering applications including daily transatlantic transmissions. These have shown a high degree of service availability at these new frequencies. In addition, this payload was used to constitute the geostationary end of a data relay link between the Inter- Orbit Communications (IOC) terminal mounted on the Agency’s EURECA spacecraft and ground controllers and experimenters during that highly successful recently completed mission.

Olympus has also been instrumental in the development of new applications, such as distance learning, data distribution and new commercial services. In the distance learning field alone, over 100 organisations, in 12 countries have used Olympus to develop training courses which are now part of the established satellite based educational infrastructure. Several of these operations have now been transferred to the EUTELSAT space segment.

In the broadcast field, Olympus was the initial test bed for a number of satellite broadcast programmes, which are now running on a commercial basis, including RAISAT and the BBC World Service. It was also used for experimental high definition TV broadcasts, to assist in the development of that new technology.

Olympus provided valuable opportunities to collect propagation data for hundreds of scientists across Europe and North America. The 20/30 GHz data, in particular, forms a major part of the statistical information available globally.
