Design of Rocket Measure-Launch-Control Platform on Ground Based on Domestic Network Equipments

High available network is the basic platform for the rocket remote measure-launch-control, it is an important technology to guarantee measure, launch and control for launching rocket remotely. By deeply researching the network architecture of rocket measure-launch-control on ground, building prototype network platform using domestic commercial network equipment, carrying out many tests for proof of concept. Solve problems such as redundant hot standby protocol selection, instant redundant fault fail-over, real-time data transmission, network platform reliability improvement and so on. Finally, designed the new generation measure-launch-control network architecture based on domestic network equipment, and analyzed the principle, reliability, real-time and security of the network in detail. The established network architecture can not only cope with complex rocket test sites, but also improve the scalability and flexibility of the network platform, and further improve the network security. The design of the new network architecture based on domestic equipment can be used for rocket remote measure-launch-control on ground.
