Abstract

A system and a method for testing of navigation systems are provided. The testing system may include a recording system that allows capturing radio frequency signals and other signals from a vehicle on the field. The recorded data can be then played back in laboratory environment using a playback system to test one or more devices. The testing system may also include a simulation system that allows generating and conveying signals to the devices under test.

Claims

1. A testing system for navigation systems, comprising:

a recording system gathering information in the field that would be experienced and relied by a navigation system during field operation, and storing the information into a database synchronized in time, wherein the stored information is used to test operation of navigation systems including a device under test.

2. The testing system of claim 1, wherein the recording system comprises an environmental signal recording subsystem that gathers signals in the field related to environment that would be experienced and relied by a navigation system during field operation, and stores the environmental signal into the database synchronized in time.

3. The testing system of claim 2, wherein the environmental signals include radio frequency signals.

4. The testing system of claim 2, wherein the recording system further comprises a motion signal recording subsystem that gathers signals in the field related to motion that would be experienced and relied by a navigation system during field operation, and stores the motion signal in the database synchronized in time.

5. The testing system of claim 4, wherein the motion signals include inertia signals.

6. The testing system of claim 1, further comprising a playback system providing the stored information to the device under test.

7. The testing system of claim 6, wherein the playback system comprises an environmental signal playback subsystem that provides the stored environmental signals to the device under test synchronized in time.

8. The testing system of claim 7, wherein the stored environmental signals include radio frequency signals.

9. The testing system of claim 7, wherein the playback system further comprises a motion signal playback subsystem that provides the stored motion signal to the device under test synchronized in time.

10. The testing system of claim 9, wherein the stored motion signals include inertia signals.

11. The testing system of claim 6, further comprising a simulation system providing simulated information to the device under test synchronized in time.

12. The testing system of claim 11, wherein the stored simulation signals include signals related to environment that would be experienced and relied by a navigation system during field operation.

13. The testing system of claim 12, wherein the environmental signals include radio frequency signals.

14. The testing system of claim 12, wherein the stored simulation signals further include motion signals related to motion that would be experienced and relied by a navigation system during field operation.

15. The testing system of claim 14, wherein the motion signals include inertia signals.

16. A testing system for navigation systems, comprising:

a recording system gathering information in the field that would be experienced and relied by a navigation system during field operation, and storing the information into a database synchronized in time, wherein the stored information is used to test operation of navigation systems including a device under test, wherein the recording system comprises;

an environmental signal recording subsystem that gathers signals in the field related to environment that would be experienced and relied by a navigation system during field operation, and stores the environmental signal into the database synchronized in time, and

a motion signal recording subsystem that gathers signals in the field related to motion that would be experienced and relied by a navigation system during field operation, and stores the motion signal in the database synchronized in time.

17. The testing system of claim 16, wherein the environmental signals include radio frequency signals, and the motion signals include inertia signals.

18. The testing system of claim 16, further comprising a playback system providing the stored information to the device under test, wherein the playback system comprises:

an environmental signal playback subsystem that provides the stored environmental signals to the device under test synchronized in time, and

a motion signal playback subsystem that provides the stored motion signal to the device under test synchronized in time.

19. The testing system of claim 18, wherein the stored environmental signals include radio frequency signals, and the stored motion signals include inertia signals.

20. A method of testing navigation systems, comprising:

gathering information in the field that would be experienced and relied by a navigation system during field operation, wherein the stored information comprises environmental signals related to environment that would be experienced and relied by a navigation system during field operation;

storing the information into a database synchronized in time; and

testing operation of navigation systems including a device under test using the stored information.
