System Overview

For MOCH4, the GSE (Ground Support Equipment) PCB is the heart of ground testing. Responsible for comprehensive sensor data acquisition, ignition, and valve actuation. It consists of 5 high-level functional subsystems: power, sensing, compute, actuation, and communications.

Stakeholders:

  • AV - Hardware: Responsible for layout of the 4-layer stackup. Refer to for GSE PCB design justifications.
  • AV - Software: Responsible for firmware, including sensing, control, and failsafe behavior. Refer to GSE behavior justifications.
  • Propulsion: Valve actuation (GN2 Fill, Vent, and MVAS), Sensor calibration
  • Launch Vehicle: Mounting specifications, Fitment constraints, Connector access, and Harnessing.
