Spacecraft assembly manufacturer PZL Warszawa-Okecie implemented testing automation to support its expanding harness shop and space assembly operations in Warsaw.

A subsidiary of Airbus Defence and Space, PZL manufactures electrical harnesses and equipped assemblies for a range of space programs including the C 295, A320 Neo, A330, A400M, MetOp and the Jupiter Icy Moons Explorer spacecraft.



Electrical testing is time consuming but essential; a bottleneck in the manufacturing process which needed to be improved.

The focus on the engineering teams at PZL was on how to best optimize testing rather than minimize the amount of tests which are carried out.


The team selected MK Test Systems because of the flexibility of their solution, which took into account PZL’s requirements for source data usage and existing cable hardware.

The test system comprised a set of five AutoMeg electrical testing control stations and 15 mobile satellite switching modules, with any number of switching modules able to be controlled by any of the control stations. At any time, any main console can be tested in any location, with up to 15,000 test points available for any project.

APG - Automatic Program Generation
When creating test programs, engineers at PZL make use of source design data in production and planning. MK Test’s third generation APG software toolset allows the use of this data in the fully automatic creation of test sequences and programs.

Programs are created in real time, allowing all design changes to be accommodated during testing.

MK Test Systems’ APG mapping tool allows PZL users to map specific source data formats, enabling the APG tool to be used across all projects.

Active Xref System
PZL also possessed several interface cables from a previous test solution. To enable reuse of these cables and rapid, error free hook up of the test system to the product, MK and PZL implemented an intelligent cable ID system.

The unique Active XRef system is double ended, allowing random hook up of the product and intermediate connections. The test system recognizes the location and sequence of hook up and adjusts the test program to suit, facilitating rapid and error free hook up.

THE RESULT?  Each stage of the electrical testing process was optimized, achieving PZL’s ΣTOP (Electrical Test Optimization) project targets.
