In order to improve the precision of earth sensor geocentric vector, a method of on-line estimation of geocentric vector deviation by using the incremental information of the inertial navigation position is proposed. The validity and accuracy of this method are verified by the simulation test. Using the high accuracy of location increment information of inertial navigation, the geocentric vector deviation of earth sensor can be estimated online, and the accuracy of earth sensor location can be effectively improved. The algorithm is simple and convenient for online application in engineering.
