Abstract

The results of stand testing of an autonomous optical navigation system designed for operation in circumlunar orbits and on the Earth–Moon flight route are considered. The system includes a wide-angle navigation camera designed to determine the spacecraft position by the planet’s horizon and by control points on its surface, a narrow-angle navigation camera used to refine the spacecraft position by control points using higher-resolution images, and two star sensors to determine the orientation of the cameras. The software and algorithmic support of the system debugged on the stand was used to process the image of the lunar surface obtained by the STS-L imaging system on the Luna-25 spacecraft. All control points from the developed catalog that were included in the image were confidently recognized. The discrepancy between the spacecraft coordinates obtained from optical navigation measurements and from the ballistic forecast was within the measurement and forecast errors.
