1. A method of intrusion detection for a relative navigation system, the method comprising:
- repeatedly projecting, from a grid generator, a set of lines defining a grid in three dimensional space to define a field bounded by the projected grid and encoded with grid data configured to identify predetermined points on the grid; and
determining a presence of an intruding object within the field.

Abstract
A relative navigation system and methods of intrusion detection for such a relative navigation system where the method includes repeatedly projecting from a grid generator a set of lines defining a grid into three dimensional space to define a field bounded by the grid and encoded with grid data configured to identify predetermined points on the grid and determining a presence of an intruding object within the field.

11. A method of detecting an intruding object, the method comprising:
-
repeatedly projecting, from a grid generator located on a transmitting object, a set of lines defining a grid and encoded with grid data configured to identify predetermined points on the grid; receiving at least a portion of the projected grid on a detector module located on the receiving object; and determining a presence of an intruding object located within the grid and between the transmitting and receiving objects based on at least one characteristic of the projected grid. - View Dependent Claims (12)

13. A relative navigation system, comprising:
-
a grid generator projecting into three dimensional space a relative navigation grid to define a field; and a detector module for detecting light and configured to output a signal related to the detected light; and a processor operably coupled to the detector module and configured to receive the signal and determine when the signal related to the detected light is indicative of the presence of an intruding object. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
