Abstract

A method of navigating to a destination is provided. The method includes but is not limited to determining a target course for a moving target device using target positioning data and generating an intercept course using the target course and intercept positioning data received from an intercept device. The intercept course intersects the target course at a destination.

Claims

1. A method of navigating, by an intercept device, to an intercept destination to intercept a moving target device, the method comprising:

receiving, by an intercept device, target positioning data, generated at a moving target device, from the moving target device, the target positioning data including at least (i) a current geographic location of the moving target device and (ii) an intended destination geographic location of the moving target device;

generating, by the intercept device, intercept positioning data; and

locally generating, by the intercept device, a predicted target course using the current geographic location of the moving target device and the intended destination geographic location of the moving target device, and using the predicted target course and the generated intercept position data to generate an intercept course, wherein the intercept course intersects the target course at an intercept destination, the intercept destination different from the intended destination geographic location.

2. The method of claim 1, wherein the intercept device uses the intercept course to provide navigation directions to the intercept destination.

3. The method of claim 1, further comprising:

receiving updated target positioning data, generated at the moving target device, from the moving target device;

generating updated intercept positioning data at the intercept device; and

locally generating an updated predicted target course using an updated current geographic location of the moving target device and an updated intended destination geographic location of the moving target device, and using the updated predicted target course and the updated generated intercept position data to generate an updated intercept course, wherein the updated intercept course intersects the updated target course at an updated intercept destination.

4. The method of claim 1, further comprising calculating and displaying one of a distance from the intercept device to the target device, a rate of change in distance from the intercept device to the target device, and a time of arrival to the intercept destination.

5. The method of claim 1, wherein the target positioning data includes (i) latitudinal and longitudinal coordinates of the current geographic location, (ii) latitudinal and longitudinal coordinates of the intended destination geographic location, and (iii) further information indicative of at least one of directional information and speed information.

6. The method of claim 5, wherein the further information indicative of at least one of directional information and speed information is information reflecting a detected direction and speed of the moving target device.

7. The method of claim 5, wherein the further information indicative of at least one of directional information and speed information is a second pair of latitudinal and longitudinal coordinates of a subsequent current geographic location of the target device, from which direction and speed information can be inferred by comparison with the first pair of latitudinal and longitudinal coordinates of the current geographic location of the target device.

8. The method of claim 1, wherein the intercept course is the shortest course to the intercept destination.

9. The method of claim 1, wherein the intercept course is the quickest course to the intercept destination.

10. The method of claim 1, wherein the generating of the intercept course is conducted at the intercept device.

11. The method of claim 1, wherein the intercept course is generated so as to be parallel to the target course and so as to avoid a line of sight between the intercept course and the target course.

12. A wireless mobile computing intercept device comprising:

a memory;

a wireless radio; and

a processor configured to;

receive, via the wireless radio, target positioning data, generated at a moving target device, from the moving target device, the target positioning data including at least (i) a current geographic location of the moving target device and (ii) an intended destination geographic location of the moving target device;

generate intercept positioning data; and

locally generate a predicted target course using the current geographic location of the moving target device and the intended destination geographic location of the moving target device, and use the predicted target course and the generated intercept positioning data to generate an intercept course, wherein the intercept course intersects the target course at an intercept destination, the intercept destination different from the intended destination geographic location.

13. The intercept device of claim 12, further configured to calculate and display, on a display of the computing device, one of a distance from the intercept device to the target device, a rate of change in distance from the intercept device to the target device, and a time of arrival to the intercept destination.

14. The intercept device of claim 12, wherein the target positioning data includes (i) latitudinal and longitudinal coordinates of the current geographic location, (ii) latitudinal and longitudinal coordinates of the intended destination geographic location, and (iii) further information indicative of at least one of directional information and speed information.

15. The intercept device of claim 14, wherein the further information indicative of at least one of directional information and speed information is information reflecting a detected direction and speed of the moving target device.

16. The intercept device of claim 14, wherein the further information indicative of at least one of directional information and speed information is a second pair of latitudinal and longitudinal coordinates of a subsequent current geographic location of the target device, from which direction and speed information can be inferred by comparison with the first pair of latitudinal and longitudinal coordinates of the current geographic location of the target device.
