is a standardized geospatial reference system developed by the National Geospatial-Intelligence Agency (NGA) for use across the United States Department of Defense. … GARS is primarily designed as a battlespace management tool and not to be used for navigation or targeting.
GARS divides the surface of the earth into 30-minute by 30-minute cells. and then Each 30-minute cell is divided into four 15-minute by 15-minute quadrants. and then Each 15-minute quadrant is divided into nine 5-minute by 5-minute areas. Learn More
