The project consists in designing, programming and implementing the required automatisms for the hydraulic systems and electricity easements of the future launch site ELA4 for ARIANE6.This contract concludes a historical series of 4 launch sites, consecutively automated by the Catalan company. From 1989, year when GTD secured the first ground infrastructure contract for the ARIANE5 launch site, followed by VEGA’s launch site and finally the one for SOYUZ.With this new contract, GTD completes a foursome, since they are also the prime contractor for the operational control banks of this future launcher, as well as for the fluid systems and also for the peripheral systems (low current).ARIANE 6 definitely represents a major milestone in GTD’s history, both in the development phase (until 2020) and in the future operational phase (until 2040).
