Tel-Instrument Expands SDR-OMNI with New GPS Simulator Application
Tel-Instrument Electronics Corp. is pleased to announce the availability of the new SDR-OMNI GPS Simulator Application, a powerful expansion to the SDR-OMNI platform that brings practical GPS receiver, ADS-B, and coupled autopilot testing directly into the hangar and onto the flight line.Designed for aircraft maintenance, avionics troubleshooting, and installation support, the SDR-OMNI GPS Simulator Application transforms SDR-OMNI into a portable GPS test solution capable of simulating up to 12 GPS L1 satellite channels in a controlled aircraft-on-ground environment. Using a dedicated GPS antenna coupler and multi-satellite L1 simulation, technicians can verify GPS receiver operation, support ADS-B position source validation, test coupled autopilot functions, and troubleshoot antenna or coax issues without relying on live sky conditions.
KIV-79 to KIV-77 Adapter
Upgrade to modern Mode 5 capability without redesigning your platform.
The KIV-79 to KIV-77 Adapter allows the KIV-79 cryptographic unit to operate as a form-fit replacement for legacy KIV-77 installations—preserving footprint, connector alignment, and mounting interfaces.
This adapter streamlines integration and testing, providing a plug-and-play path for upgrading existing transponder or interrogator systems to current NSA-approved Mode 5 encryption standards.
Compatible with the KIV-79 Emulator, the adapter supports seamless integration with a range of Mode 5 test environments, including the Tel-Instrument T-47/M5 and TS-4530A Test Sets.
This versatility makes it ideal for both field verification and lab-based IFF development and validation.
New T-47/M5 Software Update is Available
Tel-Instrument has released a new Software version for users of our popular T-47/M5 IFF Test Set (07.300.30). This update adds a new feature - Mode 5 L2B IN and OUT, removal of all Mode 4 components and also corrects a minor bug affecting with GPS Roll Over. The Software can easily be installed by Tel-Instrument or any of our authorized Service Centers.Note: As the software adds additional capability, international users of the T-47/M5 will need a Department of State License to receive the update.
There is a charge for the software and you can download a copy of the Technical Bulletin here:
IFF Mode 5 Emulator
The next-generation AIMS Mode 5 Identify Friend or Foe (IFF) Emulator by WebSec is designed as a modern, non-CCI replacement for legacy cryptographic devices. It can operate in place of a KIV-79 or, with an optional adapter, a KIV-77 — providing a flexible and future-ready solution for Mode 5 testing and evaluation.Physically representative of the KIV-79 form factor, the emulator supports flight line and lab use, with full implementation of Flight Line Test Mode and seamless integration with Tel-Instrument T-47/M5 and TS-4530A Test Sets. It mimics KIV-79 Crypto Host Serial Interface (CHSI) protocol behavior during power-up, initialization, and while running traffic, ensuring drop-in compatibility with existing workflows.
The emulator interoperates with other Mode 5 emulators and enhances test visibility by displaying all AIMS 04-900A Mode 5 messages in a human-readable format. Optional Active-Pro integration adds Mode 5 signal analysis capability for advanced test environments.
