Auriga™ - centralized version

Auriga™ - centralized version

Star tracker's optical head with software hosted on the spacecraft's onboard computer.

  • Software is provided as a library compatible with the satellite's onboard computer (OBC)
  • Optical heads are connected to the satellite's OBC via a SpaceWire interface with power supply
  • Software operating frequency up to 10 Hz
Auriga™ - With Electronic Unit (Stand-Alone)

Auriga™ - With Electronic Unit (Stand-Alone)

  • Embedded software in the electronic unit processes data from the optical heads (OH) and calculates attitude
  • Electronic unit allows for field-of-view synchronization in a non-centralized architecture
  • Electronic unit refresh rate of 10 Hz
CubeAuriga - Processing Unit

CubeAuriga - Processing Unit

  • CubeAuriga is a joint solution developed in partnership with CubeSpace
  • It allows up to two SpaceWire heads to be connected via a CAN interface, even though Auriga does not have a scan BUS
