The pyramid star identification technique
Webb31 jan. 2024 · First, a speed comparison is made with the state-of-the-art lost-in-space star-identification algorithm, Pyramid. This test shows that in the best case, the algorithm is on average an order of magnitude faster than Pyramid. Webb4 mars 2013 · The algorithm is based on an image-processing technique, the shortest distance transform, which transforms the camera image into a two-dimensional lookup table. The information from the database can then be efficiently inserted into this table to compare the camera image with the database.

Webb10 mars 2012 · The software includes the three standard steps in star tracking: centroiding, star identification, and attitude determination. Centroiding algorithms were developed in-house. The star identification code was adapted from the Pyramid Star Identification technique developed by Mortari. WebbThe designed star sensor is based on CCD image sensor which has a flight heritage by the university's first satellite RISING. This system utilizes a pyramid algorithm for secure constellation identification and works with a maximum update frequency of 2 Hz. Its availability is also very high in terms of the satellite's operating angular velocity.
