Extension of shuster's algorithm for spin-axis attitude and sensor bias determination
위성 회전축 및 센서 바이어스 결정을 위한 확장 Shuster 알고리즘에 관한 연구
Abstract
Shuster's algorithm for spin-axis determination is extended to include sensor bias and mounting angle as its solve-for parameters. The relation between direct and derived measurements bias is obtained by linearizing their kinematic equations. A one-step least-square estimation technique referred to as the 'closed form' solution is used, and the solution provides a more refined and decent initial guess for the subsequent filtering process contained within the differential correction module. The modified algorithm is applied for attitude determination of a GEO communication satellite in transfer orbit, and its results are presented.
