A sun sensor processing chip determination method with multiple configuration functions

Abstract

Provided is a sun sensor processing chip determination method possessing various configuration functions. The method comprises the following steps that function design verification of a sun sensor dedicated processing chip is performed; the input and output port of the sun sensor dedicated processing chip is constrained so that integrated analysis and front end design verification are realized; a 150K anti-radiation reinforcing master slice is processed, physical design is realized by adopting a CMOS0.5 mu m technology, and rear end time sequence verification is performed; and the chip functions, the number of pins and pin driving capacity are analyzed, and the packaging scheme of the sun sensor dedicated processing chip is designed and implemented. The design adopts a UART communication unit with high reliability, adopts a three-mode redundancy technology with respect to important data, and possesses the flexible configuration functions of UART communication protocols, sun sensor probe types and different obits of digital sun sensor view field monitoring code thresholds so that the requirements of different orbit satellites can be met.

Description

technical field [0001] The invention relates to a method for determining a solar sensor processing chip, in particular to a method for determining a solar sensor processing chip with multiple configuration functions, which is suitable for highly integrated and miniaturized solar sensor circuits; and belongs to the field of chip design . Background technique [0002] The sun sensor is a commonly used attitude sensor in space missions, which is used to measure the incident angle of the sun relative to the sun sensor on the spacecraft. Almost all spacecraft need to be equipped with sun sensors in order to complete the attitude control tasks of the spacecraft at various stages according to the attitude feedback information provided by the sun sensors. [0003] At present, three types of solar sensor probes, digital, analog and "0-1" are most commonly used in spacecraft. Among them, the digital sun sensor probe is used to measure the orientation of the sun and the orientation o...
