With the aim to fit the sin wave curve of a multi-position strap-down north seeking system and to calculate the real north angle accurately
the principles of the system and the algorithm of singular value decomposition(SVD) are introduced. The factors influencing the measuring precision are also analyzed. Then
the algorithm is adopted to fit curves. Experimental results indicate that the singular value decomposition is very precise
for its error sum is 1.1102V
and the squared error is 2.8mV. Moreover
for phase angle measurement
measured six times in same direction
the squared error is 24 (1). The method based on SVD can satisfy the system precision requirements of curve-fitting north seeking systems. 2011 IEEE.
