AIV & COTE

The system supports the assembly, integration and validation phases of satellite or subsystems.
The COTE system is also used during launch operations.
  • What it's for

    The system, which includes umbilical FEE connection, is used to assembly, verify, test and supply the satellite during all integration and testing activities including launch campaign.

    The system can be configured as AIV or COTE system and can be customized with additional features.
