SIT422/5 MR


The SIT422/5 MR is part of a family of MkXIIA (MkXII + Mode 5) and Mode S interrogators developed under the NGIFF program in order to provide a state-of-the-art IFF capability. This equipment is currently in use with NATO and Coalition Nations on mobile radar systems

Military identification is available with Modes 4 and 5, supported by an embedded crypto module entirely designed by the company and qualified by NATO Authorities (SECAN). Variants of the equipment can be provided for non-NATO applications, with a M4-only or National Secure Mode capability.

Mode S is also provided in order to monitor civilian air traffic for Situational Awareness purposes. The equipment has been designed for surface applications. Typical applications are medium/long range air systems.

The interrogator is packaged in a rugged single LRU, intended for hard mounting, it needs forced cooling; integration with the platform is mainly via Ethernet.
