CEA-Leti and Orolia Announce FlexFusion, A Powerful Positioning & Navigation Technology

'Combining Data from Global Navigation Satellite Systems (GNSS) and Inertial Management Units Ensures Accuracy Even During GNSS Outages. ' G RENOBLE, France ' Sept 10th, 2019 ' Leti, a research institute of CEA Tech, and Orolia, a leader in accuracy and performance for terrestrial, aeronautic and naval transportation positioning, navigation & timing applications, today announced a new sensor-data-fusion engine that ensures resilient positioning and navigation even in cases of global navigation satellite system ( GNSS) jamming or spoofing. Called FlexFusion, the algorithm technology processes data from GNSS, inertial management units (IMU) and odometers to provide precise positioning in all conditions. FlexFusion's design relies on a modelisation of GNSS and IMU (triple-axis accelerometer, triple-axis gyrometer and triple-axis magnetometer) output for synthetic trajectory generation. The fusion approach exploits Bayesian estimators, e.g. Kalman filters. The first algorithm was setup on modeling signals and its optimization relies on an extensive real-life sample database acquired through field test. This process used CEA-Leti's HYLOC reference platform, which provides a reference positioning of a few centimeters .
