“…The Doppler difference method eliminates the major effects caused by solar rotation. The velocity residual bias remains and is defined as the solar Doppler difference bias [27]. Liu et al [27] has analysed the geometric bias of the solar Doppler difference navigation system, which provides guidance for the subsequent design of the navigation system.…”

“…This step is known as phase unwrapping and is necessary before depth can be calculated. In addition to shape measuring, phase unwrapping is also needed in many phase‐related fields such as space navigation [7] and remote sensing [8, 9].…”

“…In response to this problem, two years later, Liu approximated the Mars's moons (Phobos and Deimos) to a point, and treated the Sun as a huge sphere. Under these conditions, Liu established a time dispersion model caused by the solar sphere, and the error analysis of the solar TDOA navigation was carried out (Liu et al, 2019).…”

The time dispersion effect affects the accuracy of solar time difference of arrival (TDOA) navigation. In this celestial autonomous navigation, Mars's moons are reflecting celestial bodies, and their shape affects the TDOA dispersion model. In the modelling process of traditional methods, the moons of Mars (Phobos and Deimos) are regarded as points, which causes the model to be inaccurate. In order to solve these problems, we simplified the Mars's moons into ellipsoids or solid diamonds, and then established a TDOA model with the nonspherical Mars's moons as reflecting celestial bodies through differential geometry and geometric optics. Finally, we analysed the time dispersion caused by the Mars's moons in theory. Theoretical analysis and experiments show that the point model error is 5·66 km, and the 3D model error is within 70 m. Thus, the 3D TDOA model established in this paper is meaningful. In addition, the Sun–Mars-moons–spacecraft angle, solar flare, three-axis length, and attitude of the Mars's moons have a great effect on the dispersion profile, while the Mars's moons-to-spacecraft distance has a small effect.
