PROBLEM TO BE SOLVED: To provide a radiolocation method by GPS which can obtain high positional accuracy. SOLUTION: For example, a point P' is measured at the position of a point P (correct position) by using a radio wave sent from a GPS satellite C. Current dummy range data are C-P". The dummy range data C-P' include errors, e.g. ionosphere delay. Correction range data C-P", which include no error or a very small error can be found, by adding a certain radiolocation correction value C' to the dummy range data C-P'. A radiolocation result calculated by using the correction range data C-P" is a position shown by a point P". This point P" is closer to the correct position shown by the point P than the point P'. |
