Operation of the Ariane launch vehicle and a payload - Launch preparation
Abstract
The performances of all Ariane launch vehicle and payload systems and their integration mechanisms are simulated before launch preparation, and various systems must be validated immediately before launch. The three-stage launch vehicle check points include the pneumatic, hydraulic, pyrotechnic and electrical systems and their interconnections. Attention is also given to the functionality and the programming of the on-board computers and the flight control systems. The verification procedures, covering visual, electrical, pressure, telemetry and radar tracking systems inspections are described. Satellites are verified for compatibility with the launch and separation environment before mating with the third stage. Procedures similar to those used with the Ariane are then applied during the final launch preparations. All active systems are constantly monitored by 150-200 personnel during countdown.
