Autonomous navigation method and technology implementation of high-precision solar spectral velocity measurement

نویسندگان

چکیده

The velocity information of spacecraft can be directly obtained by the autonomous navigation method based on astronomical spectral measurement. It provides complete direct measurement for traditional methods represented angle and ranging, which is great significance high precision navigation. This paper comprehensively introduces principle measurement, as well technical realization solar atomic frequency discriminator (SAFDAN) discrimination new SAFDAN first instrument to measure Doppler relative Sun. Carried CHASE mission, in-orbit experiment realized, accuracy reaches 1.93 m/s, effectively verifies feasibility technology.

Autonomous robot navigation for precision horticulture

Certain experimental horticultural operations require an autonomous vehicle capable of navigating through a field of crop plants. An image analysis system exists which can locate the crop row structure, but simple reactive control of the vehicle on the basis of this data would not be sufficiently reliable; instead a multisensor data fusion based approach is preferred. Since the vehicle must be ...
