203 satellite communications system equipment procurement project aimed to achieve the communication between main station and the four stations which located in marginal areas of domestic via the Sinosat 1satellite.

Consideration to the practical application of geographical remoteness, and the ground communication facilities could not meet the normal communication required,it was necessary to build a stellate satellite communications network platform to satisfy users needs.of the voice and data communications.

Build two-way communication links between the main station and remote stations,made operators in the main station know the operational status of each remote station at any time and realized the scene data collection through the VOIP voice communications and IP data transmission.

Overall demand for the system, follow the system design and equipment selection principle, analysis of the market is now mainstream products, focus from the system and suggested that the overall cost-effective equipment, set up satellite communications network.
