The Impact of Low-Earth-Orbit Satellites on GNSS Ambiguity Resolution
… The hardware in-the-loop simulation used a Spirent GSS7000 simulator, two NovAtel OEM7 receivers, and an open source GNSS processing tool to once again compare the speed of ambiguity resolution between GPS augmented with LEO satellites to GPS only. This simulation found a 22.4% improvement …

GNSS Hardware-In-The-Loop Formation and Tracking Control
… closed HWIL simulations are implemented using Spirent's Communication Global Navigation Satellite system (GNSS) 6560 and 8000 hardware simulators along with Ashtech, G-12 and DG-14, and Novetel OEM 628 receivers. The predictive navigation control is similar to other vision-based tracking …
