The Indian Space Research Organization (ISRO) launched a low-cost star sensor called StarBerrySense on board its Polar Satellite Launch Vehicle (PSLV) C-55 rocket on April 22, 2023. Developed by the Indian Institute of Astrophysics (IIA), StarBerrySense’s primary objective is to image the field of view, identify stars, and calculate the spacecraft’s pointing direction.
How StarBerrySense Sensor Works
The StarBerrySense sensor calculates the pointing direction by identifying the stars in its field of view. The sensor captures images of the stars and uses them to determine the spacecraft’s attitude and orientation. This information is crucial for controlling the spacecraft’s movement and keeping it on the right path.
Advantages of Using Star Sensor in Space Missions
The use of a star sensor in space missions provides the most accurate information about a spacecraft’s orientation. This is because the sensor can identify stars in the background, which provides a fixed reference point for the spacecraft’s position. It allows for precise control of the spacecraft’s movements and reduces the risk of errors and malfunctions.
PSLV Orbital Experimental Module (POEM)
The PSLV Orbital Experimental Module (POEM) is a platform for carrying out scientific experiments in space. It provides a stable platform for scientific instruments and payloads, including StarBerrySense. POEM’s primary purpose is to enable scientific experiments that require a stable and controlled environment in space.
