In the following description, only parts necessary for understanding the embodiments of the present invention will be described, and the description of other parts will be omitted so as not to obscure the gist of the present invention.
The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor is not limited to the meaning of the terms in order to describe his invention in the best way. It should be interpreted as meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely preferred embodiments of the present invention, and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.
In the meantime, prior to the detailed description, the 'location information' according to the embodiment of the present invention is a value obtained from a GPS signal received from a GPS satellite, and may be provided in coordinates such as latitude, longitude and altitude. Also, the 'position correction information' according to the embodiment of the present invention is information providing a range of error of the GPS signal according to the DGPS (Differential GPS) technique as a value, thereby enabling correction of the position information. More specifically, information transmitted from GPS satellites to terrestrial GPS receivers has an error. When there are two receivers located close to each other, the two receivers have a similar error. The DGPS technique is to obtain more precise data by canceling the common errors of the two receivers. The position correction information according to an embodiment of the present invention includes information for canceling the error. This information may be typically a pseudo range correction (PRC). The reference station that generates the DGPS signal calculates the difference between the geometric distance from each GPS satellite and the pseudo distance recorded with the C / A code data, and this difference becomes the pseudorange correction value (PRC). Further, the position correction information may further include a distance rate correction value (RRC). The RRC is the adjustment value of the pseudorange correction based on the PRC's predicted rate and varies over time. The RRC is a calculated value that should be reflected in the PRC at a certain time, thereby increasing the effectiveness of the PRC over time . Various other factors and parameters may be included in the position correction information, and basically all factors and parameters according to the Radio Technical Committee for Maritime Service (RTCM) standard may be included.
