The Navtrak Rail is calibrated with reference points spaced at quarter-inch intervals, providing a precise measurement of position. The Rail is level and aligned North to South, providing a fixed longitude and altitude during testing. |
|
|
The Navtrak Locomotive moves along the Rail under the control of a closed-loop control system. In addition to stationary testing, the Locomotive supports user-definable motion profiles, which allows dynamic testing in a repeatable environment. |
|
| The Navtrak Logger provides a physical platform for the device, power and communications. The Logger supports NMEA-format strings and can be customized to accept binary and other device-specific formats. |
|
| The Navtrak Console allows the operator to control and monitor the system via a radio link to the locomotive. Console software includes a Rail Profile Editor and software to download and process recorded data. In a few hours, several thousand lines of data can be recorded for analysis. |
|
| A Navtrak Report can be generated from recorded data for one or more devices. The Report includes standard accuracy measurements, such as Circular Error Probable (CEP), as well as more sophisticated statistical analysis. |
|
|
The Navtrak System goes beyond static testing, beyond simple road testing, and provides a controlled and dynamic environment for evaluating the accuracy of GPS and other position-reporting devices. |
