.COR 파일 확장자

File created by Trimble GIS programs, which are used to record and maintain GPS data; contains a corrected .SSF file that has undergone differential postprocessing, a technique that improves the accuracy of recorded positions from a GPS device.

COR files are generated using a base station, which is a receiver whose position is accurately known. They may also be generated using real-time differential GPS (DGPS) techniques.
