This article aims to propose an autonomous navigation method to simultaneously obtain precise position and velocity estimation of a deep space probe both with respect to Earth and with respect to the target, and estimate and correct the ephemeris uncertainty of the target that has a great influence on the navigation accuracy with respect to Earth. In this article, based on the analysis of the influences of ephemeris error on the state model, optical measurement, and the navigation accuracy, the ephemeris error is modeled. By taking the differences between the planned image and the actual image of the target as the ephemeris uncertainty measurement, the method is carried out by augmenting ephemeris uncertainty as system states, and is able to estimate and correct the ephemeris uncertainty of the target planet, and the position and velocity of the probe with respect to Earth and with respect to the target planet autonomously. The results show the influence of ephemeris error is removed from the orbital dynamics of the navigation system, and the proposed method can improve the accuracy with respect to Earth. The results demonstrate the proposed method autonomously yields superior performance with respect to Earth and with respect to the target.

“…On this basis, Lu (2013) further introduced texture features to simulate the terrain, craters and clouds on the surface of Mercury and the Moon. Huang et al (2015) presented a semi-physical simulation system of autonomous OPNAV for the Mars approach phase, but the albedo variations of Mars were not considered. Optical image generation procedures suitable for the Mars approach phase are still lacking in recent published literature.…”

High-precision line-of-sight extraction technique is essential for autonomous optical navigation during the Mars approach phase. To support future Mars exploration missions, an optical image simulation system is a necessary ground verification facility for Mars image generation and line-of-sight extraction algorithm tests. In this paper, an optical image generation procedure is first developed according to projection relationships, reference flight profiles and camera parameters. Next, a hybrid image processing and line-of-sight extraction algorithm is proposed through objective segmentation and rough edge detection, pseudo-edge elimination and precise edge detection, and robust ellipse fitting. Finally, an optical image simulation system is established, and the experimental results show that the proposed procedure can effectively simulate the optical image in the field-of-view of a Mars spacecraft, and the hybrid extraction algorithm can obtain high-precision Mars centroid information. KEYWORDS 1. Autonomous optical navigation. 2. Simulated image generation. 3. Line-of-sight extraction. 4. Sub-pixel edge detection. 5. Robust ellipse fitting.

Abstract. With the development of space optical remote sensing imaging technology, Space remote sensing systems have reached a new stage which is changing towards higher spatial resolution, higher spectral resolution, higher radiometric resolution, and higher temporal resolution. In recent years, applying TDI CCD to earth observation from space has become a growing trend, and it can make integrals to the same moving target by using multilevel sensitive units, which has improved the S/N and the dynamic range of optical system effectively. This paper proposes a semi-physical simulation system designed for space optical remote sensing based on 6-DOF motion platform. The system ignores the atmospheric radiation and it can obtain high quality images by simulating the whole physical process of the space optical remote sensing imaging chain which includes the sensor of TDI CCD, the motion platform of satellite, the ground scene, and the access to final remote sensing.
