Abstract: A method and system for a refueling drogue coupling system are provided. The system includes a coupling latch assembly coupled to the coupling outlet wherein the coupling latch assembly includes a latch member configured to matingly engage a complementary latch-receiving member of a refueling probe. The coupling latch assembly further includes a latch member actuator operatively coupled to the latch member to permit the latch member to move from a first locked position to a second unlocked position. A probe position sensor is configured to detect a position of the refueling probe. A hose tension sensor is configured to measure a tension in a hose coupled to the coupling inlet. A drogue control system is positioned on the refueling drogue coupling system and communicatively coupled to the latch member actuator, the probe position sensor, and the hose tension sensor.

Abstract: A relative navigation system projecting a grid into space from a first object a grid that is repeatedly detected from a second object having a second relative reference frame and using range and attitude between the objects to adjust the attitude or range of at least one of the first and second objects.

Abstract: A method of providing a relative navigation system by projecting into space from a first object a grid that is repeatedly detected from a second object having a second relative reference frame associated with a second origin point on the second object and using range and attitude between the objects to adjust the attitude or range of at least one of the first and second objects.

Abstract: A method of determining range between two objects, where a grid consisting of a plurality of grid lines are projected into space by the first object and detected by the second object.
