We present the design, realization, characterization and testing of an industrial prototype of a laser system, which is based on frequency doubling of telecom lasers and features all key functionalities to drive a cold atom space gradiometer based on the architecture proposed in [Trimeche et al, 2019]. Testing was performed by implementing the laser system onto a ground based atomic sensor currently under development. The system reaches a Technology Readiness Level (TRL) of 4, corresponding to an operational validation in a controlled environment. The optical architecture of the system can be adapted to other space mission scenarios.
