Ligado, which has been in a standoff with the GPS community over interference issues for more than six years, is developing a new high-precision location (HPL) augmentation system for GPS.

The new HPL service will use real-time kinematic- (RTK-) based solutions for augmentation of high-precision receivers, said Tamara Casey, Ligado’s chief technology officer, during Satellite 2017.

IRSO Launches 104 Satellites From a Single Rocket

Last week the Indian Space Research Organization (ISRO) put a record 104 satellites into orbit with a single launch, and now it’s preparing to launch Geosynchronous Satellite Launch Vehicle Mark III (GSLV Mark-III) in a few months. 

India’s Polar Satellite Launch Vehicle, in its thirty-ninth flight (PSLV-C37), launched the 714 kilogram Cartosat-2 series satellite for earth observation and 103 co-passenger satellites together weighing about 663 kilograms at lift-off into a 505-kilometer polar Sun Synchronous Orbit (SSO).
