摘要

Waltham, Mass.-based Raytheon Co. is leading a team that's bidding to build and implement the finalized GAGAN system, India's satellite based augmentation system (SBAS). This will complete the final phase of GAGAN's development, Raytheon said. It also leads the team that developed the technology demonstration system for GAGAN, or GPS-Aided Geosynchronous Augmented Navigation system. GAGAN is designed to monitor GPS satellite signals for errors and then generate correction messages to improve positioning accuracy for users.
