초록

A relative navigation system projects a grid into space from a grid generator and an object, such as an unmanned aerial vehicle, may use the projected grid to aid in the landing of the object. Methods of adjusting the projected grid including stabilizing the projected grid and orienting the grid generator relative to the earth.

청구항

1. A method of stabilizing a grid projected from a grid generator of a relative navigation system, with the grid generator defining a reference frame, the method comprising: repeatedly projecting into space from the grid generator a plurality of lines defining a grid, with the lines encoded with grid data configured to identify predetermined points on the grid; between a prior grid projection and a subsequent grid projection of the repeated grid projections, determining a change in a reference frame of the grid generator relative to the prior grid projec...
