Digital Sun Sensor Multi-Spot Operation

The operation and test of a multi-spot digital sun sensor for precise sun-line determination is described. The image forming system consists of an opaque mask with multiple pinhole apertures producing multiple, simultaneous, spot-like images of the sun on the focal plane. The sun-line precision can be improved by averaging multiple simultaneous measures. Nevertheless, the sensor operation on a ...

Error Compensation for Area Digital Sun Sensor

Compared to the error factors of the Linear Array Digital Sun Sensor (DSS), those of the Area Array DSS are complicated and methods used for error compensation are not valid or simple enough. This paper presents the main error factors of the Area Array DSS and proposes an effective method to compensate them. The procedure of error compensation of Area Array DSS includes three steps. First, the ...

A Simple Low Cost Digital Sun Sensor for Micro-satellites

A Digital Sun Sensor (DSS) has several advantages if compared to the analogue one. It achieves higher accuracy and avoids the problems with light being reflected from the Earth’s surface. The gradual degradation of the sensitivity of the elements due to radiation effects is not crucial for its proper functioning. The advances in CCD and recently in CMOS technology make possible to implement the...

Algorithm Enhancements for the SS-411 Digital Sun Sensor

This paper discusses the evolution of the SS-411 series digital sun sensor. The earlier SS-256 and SS-330 models have proven themselves in orbit on low cost satellite missions. The SS-411 represents a further hardware revision with enhanced robustness and improved attitude estimation performance. To complement the latest hardware improvements, researchers in the Space Avionics and Instrumentati...
