Presentation at 2020 Inertial Sensors and Systems - Symposium Gyro Technology

Optolink RPC LLC has made presentation «Compact near-navigation-grade IFOG Inertial Measurement Unit IMU400» at 2020 DGON Inertial Sensors and Systems (ISS) Symposium Gyro Technology,, which has been held in Braunschweig, Germany on September 15-16 2020. In published paper  and in pre-recorded Oral Presentation (wmv, pptx, pdf) (has been given by Head of Lab "Navigation and Motion Control" at LLC RPC "Optolink", Ph.D. Igor Fedorov) we presented  newest recently launched our product: ultra-compact navigation-grade inertial measurement unit IMU400, with  SWaP properties: 80×95×62 mm, 0.7 kg, 0.5 l, ≤7 W. The aim of this work was the production of pilot IMU400 devices batch and the estimation of the performance of IMU with direct approach and also with strapdown inertial navigation systems (SINS) simulation methods, which by sense is indirect way of performance observation. Main IMU400 Gyro and Accelerometer parameters are: Angle Random Walk (ARW) = 0.007 °/√hour, Bias Instability (BI) = 0.01°/h; Velocity Random Walk (VRW) = 40µg/√Hz, BI = 6µg. SINS expected performance (max): heading 0.2°×sec(lat) (1σ, 10 min align time). At this symposium the latest state of inertial sensors and navigation systems as well as gyro technologis was presented. This also includes applications of IFOG technology, the development of new systems, components and test procedures as well as investigations on cost and marketing aspects.
