A remote geolocation system is provided including an inertial navigation unit (INU) having orthogonally disposed three axis accelerometers/gyroscopes in a strap down configuration in a case, a laser range finder (LRF) aligned with one INU axis, a GPS, and machine instructions that create a virtual INU (VINU) used to determine orientation of the case at an activation point (AP) when the LRF is pointed at a target, take sequences of global positioning satellites (GPS) location data and inertial measuring unit (IMU) orientation measurements from a starting location to the AP, draw a line between the starting location and the AP, identify a longitude line (LL) passing through the line, align one VINU axis with the LL, align another VINU axis with INU detected gravity, and align a remaining VINU axis with the LRF's output at the AP.
