Abstract

The effect of LAMBDA in RTK mixed navigation is significant in the solution of integer ambiguity. At present, there are some defects in RTK dynamic positioning, for instance, its low speed of integer ambiguity resolution and high data remand for resolution. Focus on that, this paper presents a search strategy algorithm based on LAMBDA. This algorithm can solve parts of problems which integer ambiguity resolution can not deal with, then advances the calculate speed of Real-Time kinematics integer ambiguity resolution, and finally satisfy the requirement of dynamic positioning.
