Embodiment Construction
[0056] The flow chart of TDICCD camera integration time calculation method is shown in Fig. 4, including four processes of high-precision orbit simulation, calculation of photographic point position vector data, radial velocity elimination, and solution of integration time.
[0057] (1) High-precision track simulation
[0058] First, vector simulation is performed using high-precision track simulation software, and the software used in this embodiment is STK. Input the number of satellite orbit elements in STK, build a remote sensor in the satellite, set the installation angle of the remote sensor to simulate TDICCD camera imaging, because the remote sensor itself can only provide the longitude, latitude, oblique distance data and remote sensing of the intersection point of the boresight and the earth The position vector data of the intersection curve (pattern intersection) between the sensor envelope and the earth, so a remote sensor with a field of view of 0 degrees is used ...
