Technology Areas
IISI Corporation has over 20 years of experience in US Government sponsored R&D with two main technology focus areas:
- Remote Sensing - Tagging, Tracking, and Locating (TTL)
- Unconventional Communications (UC)




Remote Sensing - Tagging, Tracking, Locating (TTL)
IISI’s Remote Sensing Area consists of Tagging, Tracking, Locating (TTL) technology and Low Observable technology. We have successfully delivered TTL systems that operate from the Ultraviolet to Millimeter wave. This includes exploitation of existing and emerging architectures such as cellular networks and the Internet.
Each system has its unique technologies and associated challenges. IISI provides R&D for end-to-end capabilities that employ active/passive tags, detection/exploitation systems, as well as operator training. These detections systems can be handheld, airborne, or space borne depending on operational constraints.
IISI has a highly qualified material science team designs tags with unique signatures to either take advantage of existing sensors characteristics or work with custom-designed sensors.
IISI has a field-testing capability that can provide test and evaluation or ground-truthing services. Site surveys with GPS mapping, test and evaluation plans, weather data collections, and spectral irradiance data collection provide the US Government with controlled experiments for validating system specifications.

Atmospheric Attenuation for Existing Sensor Sensitivity Ranges
Unconventional Communications (UC)
The Unconventional Communications Technology Area consists of systems that covertly convey either voice or data information. These methods employ both RF and optical methods to transfer the information. They provide another security layer to covert communication methods by controlling the emission properties of the system.
By taking advantage of data on counterintelligence methods employed in an area of interest, IISI can develop a data transfer system that avoids these methods. IISI has successfully delivered concealed and open unconventional communications systems for both voice and data transfer.
