Generic Engineering Model

Price on request

The Generic Engineering Model (GEM) has been developed with the aim of providing nanosatellite developers with a standard and integrated setup to jumpstart their payload and software development. Its accessibility and versatility also make it a relevant and affordable tool for educational and outreach purposes.

The GEM platform has an architecture based on the previous ISIS successful missions. It includes CubeSat subsystems with high heritage to provide a reliable and representative environment of development.

The work done on this bus can be easily implemented on a future or on-going Flight Model satellite project. Furthermore, the setup includes all required ground support equipment and software libraries for interfacing with the satellite.

  • IGIS (ISIS Generic Interface System) The IGIS is a group of components that have been designed to provide a iiigeneric interface system to nanosatellites. A single EGSE connector is used to connect to the satellite during iiiground based testing and launch preparation as well as to “arm” the satellite for flight mode.
  • AntS Electrical Model The AntS Electrical Model is a functional reusable model of the AntS system that uses iiiLEDs and jumpers to simulate and monitor the different states of the antennas.
  • Communication GSE The unit comes as a UHF/VHF transceiver compatible with ISIS low rate radio products in iiiVHF and UHF. This product is perfect to emulate a ground station during end-to-end testing in the lab, at test sites iiior at the launch site.
  • Electrical GSE The EGSE and umbilical cord forms the ground side of the IGIS. It connects directly to the iiiinterface board on the satellite and allows testing and monitoring of the satellite hardware with basic iiilaboratory equipment. It also allows battery management of the integrated satellite battery.
