The ground support electronics system, electronics, batteries, connectors, and hard shell case, is kept in an enclosure known as the Ground Operations Device Box (G.O.D. Box). The primary components of the system include an Intel NUC computer on which Olympus runs and a custom board that communicates with the computer, called Hyperion. Hyperion extends the computers capabilities to extensive data acquisition and valve control. The NUC communicates to the ground station with a 2.4 GHz LAN extender.
During tests and launch, commands are executed via a computer at the control station using the user interface Gaia. Commands are transmitted to the NUC in the G.O.D. box, which then relays them to either Hyperion or Kronos. The NUC also interfaces with the rocket's avionics through a data umbilical in order to obtain further data during fueling, and to initiate processes on the rocket. Analog data on temperatures, pressures, and loads are read, digitized, and sent to the NUC where they are stored, by Hyperion or Kronos/Hermes.
The NUC and Hyperion are both mounted in the G.O.D Box with all the necessary auxiliary equipment for the G.O.D. Box to be a standalone system, not requiring any external power. Inside, a 100 AH battery provides power to Hyperion and the NUC. The front panel of the G.O.D. Box includes master power and fans switches, and environment proof connectors for all the servos and sensors. The fans are also filtered to ensure no dust penetration into the G.O.D. Box.
