JAVAD GNSS Tracks IRNSS Signal

October 2, 2014By

JAVAD GNSS has published a chart showing that it has tracked the IRNSS (Indian Regional Navigational Satellite System) L5 signal. Shortly after the Indian Space Research Organization (ISRO) released its IRNSS Signal in Space Interface Control Document (ICD), JAVAD GNSS was able to track the L5 BPSK signal from both 1A and 1B satellites. Ability to track IRNSS L5 will be added to all... read more
