| description | This paper presents a star-tracking algorithm to determine the accurate global orientation of autonomous platforms such as nano satellites, <inline-formula> <math display="inline"> <semantics> <mrow> <mi>U</mi> <mi>A</mi> <mi>V</mi> </mrow> </semantics> </math> </inline-formula>s, and micro-drones using commercial-off-the-shelf (<inline-formula> <math display="inline"> <semantics> <mrow> <mi>C</mi> <mi>O</mi> <mi>T</mi> <mi>S</mi> </mrow> </semantics> </math> </inline-formula>) mobile devices such as smartphones. Such star-tracking is especially challenging because it is based on existing cameras which capture a partial view of the sky and should work continuously and autonomously. The novelty of the proposed framework lies both in the computational efficiency and the ability of the star-tracker algorithm to cope with noisy measurements and outliers using affordable <inline-formula> <math display="inline"> <semantics> <mrow> <mi>C</mi> <mi>O</mi> <mi>T</mi> <mi>S</mi> </mrow> </semantics> </math> </inline-formula> mobile platforms. The presented algorithm was implemented and tested on several popular platforms including: Android mobile devices, commercial-micro drones, and Raspberry Pi. The expected accuracy of the reported orientation is [0.1°,0.5°]. |
