JTU is a software-based tactical data link testing tool which greatly increases the speed and accuracy with which Link 16 JTIDS implementations can be tested, in situ or on the bench.
The JTU was developed initially to support the rigorous JTIDS testing requirements for the new Sea King Mk7 helicopter that has recently entered service with the Royal Navy. It is planned to also be used to test the L16 implementation of the Nimrod aircraft.
Using a laptop PC the software executes a variety of JTIDS scripts, which allow messages to be transmitted to the platform under test via RF cable or antenna. The tool is provided with a rich library of test scripts, reducing the time needed to perform effective testing.
Proven test scripts can be used to reduce the time spent on regression testing. Test scripts can be shared between users to create common testing strategies and improve interoperability. JTU organises the test results files, for use in post-testing analysis, archiving or copying into other applications such as MS Word or MS Excel.
Benefits
- Ease of use
- Reduced Testing Time and Manpower
- Allows easy and quick regression testing via proven script library
- Minimise Risk - by giving the operators confidence in the implementation and mission system
- Operationally proven
- Speeds up programme development, by not only testing the system but providing data and examples for reporting problems found back to the contractors
- Reduces the need for live flights, and therefore cost
- Improved interoperability
- Creating a standard script library will allow a common testing policy to be used by different platforms
