Abstract In GNSS control network adjustment，it is neccesary to convert GNSS baseline vector error between different coordinate system.A formula was derived to convert GNSS baseline vector error from space rectangular coordinate system to geodetic coordinates，and from geodetic coordinate system to the Gauss plane rectangular coordinate system.Due to unit of the parameters of GNSS baseline vector error in the space rectangular coordinate system is different fron the geodetic coordinate system，the angle errors in geodetic coordinate system is converted to length error with curvature radius of meridian and radius of parallel circle.On this basis，the conversion of GNSS baseline vector error from the space rectangular coordinate system to station rectangular coordinate system was carried.The test result shows that the formula is correct，and easy to form.
