Cornell University Sat

CUSat is a multi-year effort to design, build, and launch an autonomous in-orbit inspection satellite system. The satellite will allow us test the accuracy and viability of the carrier-phase differential GPS (CDGPS) algorithm. We hope to prove the algorithm accurate to less than 10 cm by comparing the CDGPS navigation solution to the known distance between GPS antennas. CUSat will use this relative GPS information to help determine and control its attitude. This is the first step towards having a multi-satellite system use the CDGPS algorithm to aid in autonomous inspection. CUSat is the winner of the University Nanosat-4 Program which aims to educate the future aerospace workforce and develop new space technologies.
