N2 - Micro Position and Orientation System (POS) is the key motion compensation equipment of low-cost airborne remote sensing system, which is developed based on Inertial Navigation System (INS) and Global Navigation Satellite System (GNSS) integrated navigation technology. However, due to the low-precision of Micro Electro Mechanical System (MEMS) gyroscope and accelerometer, micro POS is difficult to realize self-alignment and long-time high-precision navigation. To solve this problem, a micro position and orientation system based on dual antenna for airborne remote sensing is designed and developed. The system is composed of Inertial Measurement Unit (IMU) based on MEMS gyroscope and accelerometer, and GNSS with dual antenna. Firstly, the initial alignment is carried out based on accelerometers and dual antenna. Then, the navigation information is updated by inertial navigation algorithm, and the Kalman filter and Rauch-Tung-Striebel (R-T-S) smoother are used to estimate inertial error and improve navigation precision. Finally, flight experiment results indicate that micro POS has a great performance.
