GNSS Receivers Keep Mapping Drone at Optimal Distance from Rugged Terrain

IG Inside Global Navigation Satellite Systems Engineering, GNSS Policy, and Design Navigate Any Environment, Road or Underground Three different low-cost r integrations, covering vehicle navigation in a range of environments, will be covered in a February 12 webinar, "Automotive-Grade GNSS + Inertial for Robust Navigation." Attendees will learn about the options available under both GNSS- centric and inertial-centric paradigms. In both realms, low-cost sensors now accomplish so much more than they ever could before. Registration is free at this link. Vehicle navigation for actively engaged drivers represents today's largest, fastest growing segment for positioning technologies. Of the three possibilities covered in this webinar, two combine GNSS and MEMS inertial, with different advantages alternately for favorable or unfavorable sky/signal conditions. A third exploits completely GNSS- denied environments. senso Low-cost sensors can meet requirements for map-matching, telematics and fleet-vehicle tracking, functioning in challenging environments such as urban canyons, tunnels and parking garages. A consistent and reliable positioning on the meter level, capable of withstanding 5 to 10-minute outages, answers this growing need. Finally, for environments completely denied of GNSS signal availability, such as underground mines or construction in tunnels, new applications of inertial technology bring improved results without significant sensor costs. The expert panel will guide the audience through the intricacies of GNSS-inertial integration from three varying yet complementary vantage points: a sensor-agnostic software that uses inertial measurements to wring precision out of carrier-phase GNSS-not pseudoranges- without connecting to vehicle systems; an automotive dead reckoning solution employing tightly coupled GNSS, MEMS accelerometers and gyros, and various vehicle sensors, that can continue to operate without GNSS; a constrained inertial system that provides a full solution in a completely denied GNSS environment: underground!
