Satellite ground system manufacturer GMV of Spain said Jan. 14 that it had been awarded a contract from Waltham, Mass.-based Raytheon to develop a prototype algorithm intended to help improve the accuracy of navigation devices built for use with India’s regional GPS-augmentation system.

Raytheon is under contract to deliver the ground infrastructure for India’s GPS-Aided Geosynchronous-Augmented Navigation (GAGAN) system and recently signed an agreement with the Indian Space Research Organisation to incorporate modifications meant to increase the availability of precision approach guidance for civil aircraft in the equatorial region.

GMV said in a press release it is helping Raytheon with the project by developing a prototype algorithm for the detection of ionospheric effects that can interfere with precision navigation in equatorial regions.

GMV said it expects to deliver its portion of the project in June.
