• We developed an ambiguity resolution algorithm for attitude determination using multiple GPS antennas. It is focused on reducing computational loads using a geometrical approach. By defining a new decision variable for stochastic verification, overall computational loads are effectively reduced with respect to the chi-square model. This paper also uses the first base vector estimated as line-of-sight vector to obtain a second base vector. The additional 1-D search space is sufficient to resolve cycle ambiguity of the second base vector for complete attitude determination. Consequently it is possible to resolve the multi-baseline cycle ambiguity using a single baseline algorithm load.
