Abstract: The present invention provides a method of performing a position measurement on the basis of a signal from a global navigation satellite system (GNSS). The method includes: receiving initial position information; estimating an initial value of a multipath error through a measurement of the GNSS signal on the basis of the received initial position information; estimating a multipath error from the initial value of the multipath error on the basis of a change in the measurement; removing the estimated multipath error from the measurement of the GNSS signal; and performing the position measurement on the basis of the GNSS measurement from which the multipath error is removed.
