The rescue request signal receiver 210 receives an emergency rescue request signal from the rescue request terminal 100. Here, the rescue request signal receiver 210 may be directly connected to the rescue request terminal 100 or may be connected and communicated through the communication network 500.

The location information correction unit 220 detects the location information of the rescue request terminal 100 included in the emergency rescue request signal. In addition, the position information correction unit 220 corrects the position information of the rescue request terminal 100. Here, the location information correction unit 220 may correct the location information of the rescue request terminal 100 through a plurality of steps. In particular, the position information correction unit 220 may accurately correct the position information of the rescue request terminal 100 through the first to third correction steps.

First, as shown in FIG. 3, in the first correction step, the location information corrector 220 is within a set range except for location information that is out of a preset range among a plurality of location information generated by the rescue request terminal 100. The location information is generated as the first location information. Here, the first location information may include information about each of latitude and longitude. In addition, the first location information may be generated as one representative location information from GPS information within a range set using an average, median, or standard deviation.

Meanwhile, the location information corrector 220 may set the difference between the location information of the preset reference point and the GSP information received through the GPS receiver as the error verification offset information, according to another exemplary embodiment. In addition, the position information corrector 220 may generate second position information by applying the error verification offset information to the first position information. The error verification offset information may be set as a difference between the position information of the reference point and the GPS information received through the GPS receiver. In this case, the position information of the reference point may be set by confirming the correct position coordinate in advance.

Specifically, the location information correction unit 220 compares the accurate location information of the reference point shown in Table 1 below with the GPS information received at the reference point shown in Table 2, and sets the error verification offset information shown in the table as the difference value.
