The field of space technology is set to make a significant stride as researchers from Indian Institute of Astrophysics (IIA) have developed an inexpensive star sensor called Starberry-Sense for astronomy as well as small CubeSat class satellite missions. The Starberry-Sense offers an effective solution for promoting the orientation of small CubeSat class satellite missions in space.
This invention, completed under the Department of Science and Technology (DST), India, is all set for deployment on the PS4-Orbital Platform by the Indian Space Research Organization (ISRO). It is expected to be used in CubeSats and other small satellite missions in the future.
Understanding Star Sensors
Star sensors stand as an integral element in the world of space technology. They are precise attitude determination sensors that play a pivotal role in determining a satellite’s orientation in space. Equipped with an electro-optical system, these sensors capture images of stars and compare them with a star catalogue to identify angle deviation of the satellite and alter its posture accordingly.
Key components of a star sensor include a baffle, optical system, detector, and electronic and image processing system.
Why Choose Starberry-Sense?
Starberry-Sense holds the potential to revolutionize the way star sensors are utilized in space technology missions. Unlike existing market alternatives, Starberry-Sense proves to be less expensive by about 10%. The secret behind its cost-effectiveness lies in the use of commercial off-the-shelf components that are easy to procure.
The whole system has been developed using Raspberry Pi Zero – a cost-effective, compact (smaller than a credit card) computer featuring low power consumption. Its ability to run custom software makes it an ideal platform for star sensor applications.
