Disclosed are an apparatus for generating a user's virtual observation and a method thereof. More particularly, the apparatus for generating user's virtual observation according to an embodiment includes a master reference station carrier observation receiver configured to receive a carrier measurement of a master reference station of a first network from a preset area divided into a first network to an n-th network (where n is a positive integer) by multiple reference stations; a spatial separation compensation correction information receiver configured to set a path from the master reference station of the first network to a user's terminal and to receive spatial separation compensation correction information of at least one network corresponding to the set path among the first network to the n-th network; and using a user's virtual observation generator configured to generate a virtual observation, in which a spatial separation error of a user's positioning is compensated, using the carrier measurement of the master reference station of the first network and the spatial separation compensation correction information of each of the at least one network.
