Abstract

A sensor system having multiple sensors and having a grid generator projecting into space a relative navigation grid and a method of utilizing multiple airborne sensors operably coupled to an aircraft and coordinating the sensor outputs from the airborne sensors based on the determined spatial position of the multiple sensors and a method for utilizing multiple airborne sensors.

First claim

What is claimed is:

1. A sensor system having multiple sensors coupled to at least one aircraft, wherein each of the sensors is operably coupled to the at least one aircraft through a tether, each sensor coupled proximate to one end of each tether and the other end of each tether being attached to the aircraft, the sensor system, comprising:
a grid generator projecting into a space behind the aircraft a relative navigation grid;
multiple sensors located within the relative navigation grid and providing sensor outputs;
a position detector configured to detect the position of each of the multiple sensors relative to the relative navigation grid and providing corresponding position outputs; and
a coordination engine configured to coordinate the multiple sensor outputs based on the corresponding position outputs provided by the position detector and generate a single coordinated sensor output, wherein the coordination engine uses the precise position of the multiple sensors in the navigation grid to provide coordination data necessary to combine the data into the single coordinated sensor output such that dimensional artifacts can be extracted from the single coordinated sensor output and true wide field stereolithography allowed.

2. The system of claim 1 wherein the position detector comprises a position sensor for each of the multiple sensors, with each position sensor outputting a position signal indicative of the position of the sensor within the relative navigation grid.

3. The system of claim 1 , further comprising a controller having a memory and a set of executable instructions, provided in the memory for determining the position of the multiple sensors based on the position outputs.

4. The system of claim 1 wherein the multiple sensors are at least one of an EO/IR, SWIR, MWIR, Multispectral, Hyperspectral, SAR, SIGINT, SONAR, and Radio type.

5. The system of claim 1 wherein the grid generator and the position detector are mounted to the at least one aircraft.

6. The system of claim 1 wherein the multiple sensors are positionable relative to the at least one aircraft.

7. The system of claim 1 , further comprising at least one drogue coupled to the tether and at least one of the multiple sensors is operably coupled to the drogue.

8. The system of claim 1 wherein the multiple sensors are remote from the at least one aircraft.

9. A method of utilizing multiple airborne sensors operably coupled to at least one aircraft and providing a sensor output, wherein each of the sensors is operably coupled to the at least one aircraft through a tether, each sensor coupled proximate to one end of each tether and the other end of each tether being attached to the aircraft, the method comprising:
projecting a relative navigation grid from the at least one aircraft into a space behind the aircraft;
determining a spatial position of the multiple sensors within the relative navigation grid; and
coordinating the sensor outputs from the multiple airborne sensors into a single output based on the determined spatial position of the multiple sensors within the relative navigation grid, wherein the coordinating is based on the precise position of the multiple airborne sensors within the relative navigation grid to provide location data necessary to combine the outputs such that extract dimensional artifacts can be extracted from the single output and true wide field stereolithography allowed.

10. The method of claim 9 , further comprising altering a position of at least one of the multiple sensors based on the determined spatial position of the multiple sensors.

11. The method of claim 10 wherein altering the position of at least one of the multiple sensors comprises using a steering force acting on the at least one of the multiple sensors.

12. The method of claim 9 wherein the determining a spatial position of the multiple sensors within the relative navigation grid comprises receiving a position signal indicative of the position of the sensor within the relative navigation grid from a position detector.

13. The method of claim 12 wherein the determining a spatial position of the multiple sensors within the relative navigation grid comprises a controller executing a set of executable instructions for determining the position of the multiple sensors based on the position signal.
