The invention relates to an inertial sensor error calibration system for a high-precision GNSS (Global Navigation Satellite System) receiver, which comprises a wireless communication subsystem used for being responsible for communication related operation of an Android PDA (Personal Digital Assistant) handbook and the high-precision GNSS receiver; the data processing subsystem is used for analyzing various original output information of the receiver, calculating the attitude, calculating error calibration parameters and storing and feeding back related data; and the sensor calibration subsystem is used for acquiring, fitting and calibrating data of the inertial sensor so as to complete error calibration of the inertial sensor and carrying out magnetic field data contour graphical display. Therefore, the error correction parameters based on the Android platform can be generated and returned, the precision requirement of a user for assisting receiver engineering measurement by using an inertial sensor is ensure
