Not just supporting players, alternative positioning, navigation and timing (PNT) systems strengthen, augment and — when needed — replace GNSS. We explore how companies are using alternative PNT, and talk with John Fischer of Orolia and Alexis Guinamard of SBG Systems about their companies’ latest developments. Since the 1990s, GPS has provided the United States military with a substantial tactical... read more
Testing the full operational performance of GPS/inertial systems usually requires expensive and time-consuming field testing on an appropriate moving vehicle platform. Spirent’s SimINERTIAL system emulates inertial sensor outputs while simultaneously simulating GPS RF signals. This enables controlled, repeatable testing of integrated GPS and inertial units, reducing the need for field trials. SimINERTIAL is housed in a PC platform equipped with... read more
Honeywell, under a contract with Lockheed Martin, will supply guidance and navigation systems for NASA’s upcoming Artemis missions, which will fly humans to the moon for the first time since 1972. The companies are supplying key components to NASA’s Orion spacecraft fleet for the Artemis missions. Components include the barometric altimeter, the inertial measurement system, and the GPS receiver. Honeywell... read more
GNSS positioning is highly accurate and reliable — until satellite signals are disrupted. Hexagon | NovAtel has developed SPAN technology that integrates GNSS positioning with inertial measurements for a three-dimensional understanding of position and orientation. SPAN technology delivers accurate heading, velocity, azimuth, pitch and roll. NovAtel SPAN-enabled receivers and enclosures are effective across applications, including marine environments to monitor heave movements... read more
