Abstract:	NovAtel CORRECT™ with TerraStar-D enables global real-time PPP services for land and aerial applications using corrections generated by TerraStar. With only a TerraStar-D enabled and subscribed NovAtel OEM6 GNSS receiver and L-band supporting antenna, users can get global centimeter-level positions in real-time. The performance of NovAtel CORRECT with TerraStar-D is tested in this paper using a variety of kinematic and static datasets. Based on the results, TerraStar-D provides position solutions with between 4 and 6 cm horizontal Root Mean Square (RMS) errors. That is sufficient for many practical applications in agriculture, machine control, near-shore surveying and mobile mapping. The NovAtel CORRECT with TerraStar-D performance is compared against solutions derived from several other PPP correction feeds: the openly-available real-time International GNSS Service (IGS) and Centre National d'Études Spatiales (CNES) services, NovAtel’s entry-level PACE service (with corrections provided by Natural Resources Canada), post-processed IGS final products and the commercial OmniSTAR G2 service. Based on the results, TerraStar-D provides significantly better performance than the IGS, CNES and PACE correction services and similar performance compared to OmniSTAR G2 and IGS final post-processed corrections.
