We report about improved reliability on positioning information obtained by a GPS receiver. The basic strategy to obtain positioning information with high reliability was proposed as following. Every positioning information are calculated using every combination among satellites that GPS receiver can catch. In case which the collective point exists, the point is estimated as the correct positioning information. In case which the collective point does not exist, the positioning information with reliability is not able to be obtained. Experimental results using this method demonstrated that the precision of the coordinate obtained by GPS receiver was improved. This method for GPS is useful for obtaining positioning information with reliability
