Target locator device and methods

Systems and methods for a target locator device are provided. In one embodiment, a target locator device comprises: a high performance gyroscope; an inertial measurement unit including an accelerometer triad and a gyroscope triad; a rangefinder; a global navigation satellite system (GNSS) receiver; and a processor coupled to the high performance gyroscope, the inertial measurement unit, the rangefinder and the GNSS receiver. The processor derives an alignment heading from a heading measurement provided by the high performance gyroscope. The processor calculates a heading to a target based on a deviation from the alignment heading as measured from a heading and elevation measurement determined from the inertial measurement unit.
