摘要： In a mobile-unit positioning device, phases of pseudo noise codes carried on satellite signals from satellites are observed at a mobile unit to measure a position of the mobile unit. A pseudo distance between one of the satellites and the mobile unit is measured for every satellite during a stop of the mobile unit using an observed value of the phase acquired during a stop of the mobile unit. An error index value indicating an error of the measured distance is computed based on the distances measured at points in time during a stop of the mobile unit. A weighting factor is determined based on the index value computed for every satellite. A weighted positioning computation using the determined weighting factor is performed to determine a position of the mobile unit during movement using an observed value of the phase acquired during movement.

摘要： A linear regression equation is comprised of the objective variables and the explanatory variables. The objective variables are comprised of the L1 carrier phases, the L2 carrier phases, the C/A code pseudorange, the P(Y) code pseudorange, the clock error data, the delay data of the ionosphere, and the delay data of the troposphere that related with every satellite respectively. The explanatory variables are comprised of at least the integer ambiguity and a receiver's position.The receiver's position has been linear-approximated by using the estimation results of the passed receiver's positions. Applying a least square method to the regression equation, the integer ambiguity and the receiver's position is estimated.
