摘要：NOVELTY - The method involves confirming the original ambiguity floating point and original variance covariance matrix according to a ground receiver. The integral transform of the ambiguity floating point and original variance covariance matrix of the original floating point are performed. The target function is obtained with the integer least-squares estimation rule. The proper initial search space before the first search is calculated using the conditional estimate of zi. The improved integer ambiguity search formula is provided to obtain the locating result. USE - Improved integer ambiguity search method. ADVANTAGE - The ambiguity search candidate point number and unnecessary redundancy calculation are reduced. The calculation efficiency of the ambiguity is improved and the ambiguity resolution efficiency is made reliable. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating improved integer ambiguity search method.
