Partial modernization of "Watchman" and "AR-51" radars - replacement of signal processing and plotter system. The following systems were replaced: signal processing system, plotter system, path forming system, remote control, displaying unit. These systems and units were developed and manufactured by us. In these areas we applied the most modern, industrial and military used components, parts and equipment. As a result of the modernization much more controlling activity can be performed from the operators workplace, and the work of the operators became more secure.

The self-written softwares provided opportunities for further simplifications. With the evolving of remote control, most of the locator activities can be tracked through an IP based network and controlled from a remote centre.
