Monitoring, recording and testing of navigation systems
First Claim
1. A testing system adapted to evaluate navigation systems, the testing system comprising:
- a recording system adapted to collect and record signals received and interpreted by a navigation system during field operation;
a time-synchronized database adapted to receive and store data representing the signals collected and recorded by the recording system;
wherein the stored data is able to be used to test operation of one or more navigation systems under test.

Abstract
A testing system is described. The testing system is adapted to evaluate navigation systems. The testing system includes: a recording system adapted to collect and record signals received and interpreted by a navigation system during field operation; a time-synchronized database adapted to receive and store data representing the signals collected and recorded by the recording system: wherein the stored data is able to be used to test operation of one or more navigation systems under test. A method of testing navigation systems includes: gathering data that would be received and interpreted by a navigation system during field operation, wherein the gathered data includes data associated with received radio signals; storing gathered data in a time-synchronized database; and using the stored data to test the operation of one or more navigation systems. A system adapted to test navigation systems includes: a recording system; a playback system; and a simulation system.

17. A system adapted to test navigation systems, the system comprising:
-
a recording system adapted to gather radio frequency signals and motion signals in the field that would be received and interpreted by a navigation system during field operation, and store the signals in a time-synchronized database; a playback system adapted to provide the stored signals to a navigation system under test to recreate conditions experienced by a navigation system during field operation; and a simulation system adapted to provide simulated signals to the navigation system under test, wherein the simulated signals are signals that a navigation system would receive and interpret during field operation. - View Dependent Claims (18, 19, 20)
