Indian Institute of Astrophysics researchers develop low-cost star sensor

• The star sensor Starberry-Sense can help small CubeSat class satellite missions find their orientation in space.
• Any satellite needs to know where it is pointed in space, and the instrument used for this purpose is called a star sensor.
• The position of stars in the sky is fixed relative to each other and can be used as a stable reference frame to calculate the orientation of a satellite in orbit.
• Features of Starberry-Sense
  • The brain of the instrument is a single-board Linux computer called Raspberry Pi, which is widely used among electronics hobby enthusiasts.
  • Based on commercial/off-the-shelf components, this star sensor costs less than 10% of those available in the market.
  • It is ready for launch on the PS4-Orbital Platform by ISRO and can be used for CubeSats and other small satellite missions in the future.
  • The star sensor has successfully undergone the vibration and thermal vacuum test that qualifies it for a space launch and operations, and these tests were conducted in-house at the environmental test facility located at the CREST Campus of IIA in Hosakote.

CubeSats

• CubeSats are a class of research spacecraft called nanosatellites.
• CubeSats are built to standard dimensions (Units or “U”) of 10 cm x 10 cm x 10 cm.
• They typically weigh less than 1.33 kg (3 lbs) per U.

• The pollution on this island mainly comes from fishing nets, which are very common debris on Trinidad Island’s beaches.
