SNC300C-B0 UAV Inertial Navigation System

Обзор

SNC300C-B0 is a compact inertial navigation system using fiber optic gyroscope (FOG) and micro electro mechanical system (MEMS) accelerometer. It can use external GNSS accurate timing and positioning information for Inertial / satellite integrated navigation. When external GNSS information is invalid, the inertial navigation system has high pure inertial navigation accuracy retention ability. ▶ It has the function of shaking base / moving base alignment ▶ External GNSS / atmosphere multi information fusion integrated navigation ▶ The accuracy is maintained for a long time without external information ▶ Support users to customize on demand 2. Main application fields ▶ Ground, tunnel and other track detection and measurement ▶ High precision stable platform 3, Physical Size and Electrical Characteristics, System Performance Indicators Physical dimensions and electrical characteristics Dimensions: 111mm x 72mm x 43mm (length, width and height) Operating temperature: - 40 ℃ ~ + 60 ℃ Storage temperature: - 45 ℃ ~ + 70 ℃ Vibration: 5 ~ 2000Hz, 6.06g (with damping) Impact: 30g, 11ms (with damping) Continuous working time: > 24h Grounding characteristics External GNSS valid, single point: 1.2m (RMS) External GNSS valid, RTK: 2cm + 1ppm (RMS) Pure inertial horizontal positioning holding ①: 100M / 5min (CEP) Airspeed combination horizontal positioning holding ②: 1nm / 30min (CEP) Dual antenna: 0.2 / L (L is the baseline length) (RMS) Course keeping: 0.3 / 30min (RMS), 1 / h (RMS) Self north seeking accuracy: 1 SECL, alignment 15min ④ GNSS effective: 0.02 (RMS) Attitude hold (GNSS failure): 0.3 / 30min (RMS), 1 / h (RMS) Speed accuracy GNSS valid, single point L1 / L2: 0.1m/s (RMS) Zero bias stability: 0.3 / h Quartz flexible accelerometer Zero bias stability: 100 g
