Abstract

A method is provided for locating an asset equipped with a transponder which issues coded signals when activated by a control communication received from a communication source or by a local event. The coded signals enable a tracking unit to direction find said asset. The method comprises the steps of: providing said tracking unit with map data compatible with a navigation system on-board the tracking unit; and displaying a location indicated by said map data on a map display of said navigation device, wherein said map data is indicative of a search location for the asset and the likely best route for recovery of the asset.

7. The method of claim 6, wherein the data defining a geographical area in which the asset is expected to be located is determined from location finding techniques.

8. The method of claim 1, wherein the step of providing said tracking unit with data indicative of a search location of the asset comprises providing data defining a geographical area in which the asset is or was known to be located.

9. The method of claim 1, wherein the step of providing said tracking unit with data indicative of a search location of the asset comprises providing data defining a geographical area in which a user of the tracking unit believes the asset is located.

10. The method of claim 1, wherein the step of providing said tracking unit with data indicative of a search location of the asset comprises providing global positioning system ‘

GPS’

data associated with the asset.

11. The method of claim 10, wherein the GPS data is provided by any one or any combination of a GPS unit on board the asset being tracked, the OCC, or any other device which together with the tracking unit and the OCC comprises an asset location system.

12. The method of claim 1, wherein the step of providing said tracking unit with data indicative of a search location of the asset comprises providing historical location data for the asset.

13. The method of claim 1, wherein the step of providing said tracking unit with data indicative of an search location of the asset comprises providing location data derived from other devices or assets or communication systems identity data.

14. The method of claim 6, wherein the data indicative of an search location of the asset includes a best estimate location for the asset.

15. The method of claim 1, wherein the search location is a search location geographical area.

22. The method of claim 1, wherein the a recommended search route displayed by the navigation system comprises an optimum search pattern of the search area takes account of any one or any combination of factors relating to the search area:

permitted road directions, traffic congestion information, traffic light layout, traffic light responsiveness, speed limit data, or radio frequency reception characteristics of the search area, other topical factors affecting the speed of transit.

31. An asset location system comprising:

an operations control centre “

OCC’

;

a tracking unit capable of receiving information from the OCC;

an asset equipped with a transponder which issues coded signals when activated by a control communication received from the OCC or by a local event, wherein said coded signals enable the tracking unit to direction find said asset, the system being configured to;

provide said tracking unit with map data compatible with a navigation system on-board the tracking unit; and

display a location indicated by said map data on a map display of said navigation device,

wherein said map data is indicative of a search location for the asset.

32. The system of claim 31, wherein the system is configured to provide said tracking unit with map data compatible with a navigation system by:

providing data indicative of a search location of the asset; and

processing said search location data into map data compatible with said navigation system on-board the tracking unit.

33. The system of claim 32, wherein the system is configured to provide the tracking unit with the data indicative of a search location of the asset and said tracking unit is configured to process said search location data into map data compatible with said navigation system.

34. The system of claim 31, wherein the system is configured to provide said tracking unit with map data compatible with a navigation system by:

receiving data indicative of a search location of the asset at the OCC;

processing said search location data into map data compatible with said navigation system on-board the tracking unit; and

transmitting said map data from the OCC to the tracking unit.

35. The system of claim 31, wherein the system is configured to provide said tracking unit with map data compatible with a navigation system by:

at the OCC, determining data indicative of a search location of the asset;
