“…The typical analytic calibration methods involve static multiposition calibration, rotation rate calibration, and dynamic-static hybrid calibration methods. The static multiposition calibration can calculate the error coefficients of IMU, but the precision is low [23]. The rotation rate calibration can give the error coefficients of angular rate channel, but not give that of acceleration channel.…”

The airborne Position Orientation System (POS) can accurately measure space-time reference information and plays a vital role in aerial remote sensing system. It may be applied in a direct georeference system for optical camera and a motion imaging system for Synthetic Aperture Radar (SAR), which further advances efficiency and quality of imaging sensors. In this paper, the operation principle and components of airborne POS are introduced. Some key technologies of airborne POS are summarized. They include the error calibration and compensation, initial alignment, lever arm error modeling, time synchronization, and integrated estimation method. A high precision airborne POS has been developed and applied to a variety of aerial remote sensing systems.

“…First, the IMU data and the GPS data are sent to the computer subsystem. Second, after the error compensation of IMU [18], [19], the strapdown navigation algorithm is used to compute the attitude, velocity, and position. At the same time, the GPS data are compensated for the lever arm effect.…”

Position and orientation system (POS) is widely applied to the various mapping sensors for airborne direct georeferencing. As the accuracy requirements vary in different mapping applications, the POS error analysis is important for the system design. In this paper, an analytical approach to the POS error analysis for ground alignment and constant-velocity flight is proposed. First, the simplified system model is obtained for the error analysis. Then, by applying the two-stage Kalman filter, the analytical relations between the attitude errors and estimation errors of the biases of the inertial sensors are derived. Finally, the experiment is carried out to confirm the effectiveness of the proposed method. The proposed method is not only effective and straightforward but also provides us some new insights into the POS error characteristics.Index Terms-Analytical relation, direct georeferencing, error analysis, position and orientation system (POS), two-stage Kalman filter.
