The existing TIGSS serialisation project includes the development and delivery of two sets of TIGSS test equipment and one Deployable Workroom (DWR). The DWR is including an ISO class 8 cleanroom. The TIGSS is designed to be operated in the DWR and in a workroom located in a building at a home base of the German Forces.

The TIGSS comprises the following components per test bench:

  • Electronic Deployable Test Solution (EDTS)
  • Optronic Deployable Test Solution (ODTS)
  • Test Program Set (TPS) for 4 LRUs to be tested, which are the Sight Head, the Head In Display, the Auxiliary Climatisation Device and the Auxiliary Washing Device


compared to UMMS (predecessor test bench):

  • Higher throughput rate
  • Much more space for the operators, test and repair of LRUs inside the DWR is possible at the same time
  • Much more general working comfort for the operator (more space, less noise, daylight inside working area…)
