LSTD
Laser Seeker Test Device

Goal

To prepare a test infrastructure necessary for performing the field tests for a “Laser Seeker” placed on the tip of guided missiles designed by a customer which is operating in the defense and aviation industry.

The testing system must;

  • Provide laser simulation compliant with the STANAG 3733 standard
  • Have a mechanical interface that can be attached easily to the product being tested
  • Easily and quickly determine errors through a user-friendly interface,
  • Be portable and durable against environmental conditions.

Solution

DEICO decided that the test set needs to be created with a rugged mobile case that is durable against environmental conditions since it will be used on the field. All of the device options to be used and the mechanical structures to be used in the case were created in this framework.

A laser source test simulator that can trigger the detectors on the “Laser Seeker” was used in the test set. Through the Embedded Box PC placed in the case the communication with the “Laser Seeker” infrastructure was established for testing devices. By using the test software developed on the Embedded Box PC the laser source simulator was made to produce sources at different frequency intervals and a comparison was made via the responses provided by the “Laser Seeker”.

The test set has a mechanical interface that can be placed in the most suitable location where it will be exposed to the “Laser Seeker’s” laser simulation. This mechanical interface enables easy placement of the device being tested on the case to enable fast continuation of the tests.

The selection, conducting and reporting of results for the tests was simplified with the Touch Screen, Keyboard/Mouse placed on the case.

Through the test software, prepared in Visual C# environment operating in the Embedded Box PC the user was enabled to select test scenarios and create a report after applying the tests.

Result

Using the designed and produced test device the user was able to easily conduct the final tests in the field before attaching the product to the guided missiles and then assemble it to the final system. The test results were obtained by comparing the source produced with the Laser Source Simulator and the laser source detected by the “Laser Seeker” and the test results were easily provided to the user on a monitor.
