Precision navigation apparatus |
摘要 |
In the disclosed apparatus, a reference image sensor continuously scans a filmed atlas of images representing terrain being overflown while a second sensor simultaneously scans the terrain. A correlator compares the signal and the reference image sensor describes a course, corresponding to that of the flying body, over the film, in response to control signals based upon the correlation results. The reference image sensor reads only the area of the film around the course.
