IS4S VICTORY-in-a-Box Proposal Selected
Auburn, AL

The National Autonomous Mobility Consortium selected the IS4S proposal to develop a VICTORY-in-a-Box. IS4S will develop a prototype of a scalable PNT hub for ground vehicle platforms using COTS/MOTS components to the maximum extent possible. Existing VICTORY-In-A-Box solutions developed by TARDEC will be leveraged to reduce cost, development time, and save space within vehicle platforms. The developed system will include a SAASM GPS receiver and precision clock to provide a PNT solution to clients using the standardized VICTORY data bus. The positioning and time transfer performance of the system will be studied and the ability to expand the system provide an assured PNT solution in GPS degraded environments will be explored. Funding for this effort is not immediately available.


IS4S Awarded Phase I SBIR for Physics Aided Inertial Navigation
Huntsville, AL

IS4S was awarded a Phase I SBIR contract to improve inertial navigation on high dynamic flight systems. This effort will produce enhanced navigation algorithms for un-aided IMUs. These algorithms will allow missiles to more effectively navigate through the severe dynamics of a missile flight. The navigators will be generic and applicable to a wide range of missiles. The algorithm parameters will be tunable to adjust to particular missile and IMU systems. This technology has potential commercial applications on many missiles and other guided munitions. The algorithms will be demonstrated interfacing with hardware IMUs to show the feasibility of incorporating them into existing product lines. The enhanced navigators would also allow lower-cost IMUs to be used in systems while still maintaining the required navigation performance.

IS4S Awarded Phase I SBIR for an Indoor, Over-the-Air, GPS Constellation Simulator
Auburn, AL

The US Army Electronic Proving Ground (EPG) awarded IS4S a Phase I SBIR to develop an indoor, over-the-air (OTA), GPS constellation simulator. The proposed system will provide a new testing capability to the DoD. Using a network of electronically scanned antenna arrays, GPS signals will be transmitted over the air inside an anechoic chamber. The system will realistically simulate satellite motion. The new capability will ease the demand on low-density testing assets (i.e. open air test ranges), ultimately becoming a cost-savings for the government. The capability could also reduce security concerns for OTA transmission of sensitive waveforms, as some of these tests could be moved to an isolated environment.

AFRL Ephemeral Security Phase II
Auburn, AL

In this work, an ephemeral security technique for keying military GPS receivers will be developed. This work will not modify the existing GPS cryptographic structure, but rather develop an overlay for providing keying information to a receiver in a manner that makes all security information ephemeral, eliminating the permanent storage of CPI within the receiver. Existing and emerging battlefield networks will be leveraged to provide a method of securely distributing keys to a GPS receiver. This technique requires a security overlay over the tactical or strategic communication network where the security overlay will provide access control based on advanced key distribution, mutual authentication, location-based access and biometric techniques. The security overlay will provide secure transmission of encrypted, black keys to military receivers through all types of tactical or strategic communication networks, including mobile ad hoc networks (MANETs). Additionally, concept of operations (CONOPS) and Tactics, Techniques, and Procedures (TTPs) needed to support the ephemeral overlay technology will be explored.

IS4S Awarded Phase I SBIR to Develop Indoor Tracking System for First Responders
Auburn, AL

The Department of Homeland Security (DHS) awarded IS4S a Phase I SBIR to perform trade studies and develop a personal First Responder navigation and tracking system for use in GPS-limited or denied environments. The system will track First Responder motion with inertial-based pedometry and will have a modular and scalable architecture to incorporate, but not rely on, other aiding sensors or information specific to the response environment (e.g. RF localization systems, maps, etc.). Trade studies will be performed to determine the best implementation for First Responders and assess the performance of vision to aid the solution. Use of standards will maximize operability with other connected systems and tools as well as send PNT solutions to the NGFR communication hub for transmission over available communication links, such as Land Mobile Radio (LMR) or Long-Term Evolution (LTE) networks. The hardware will require minimal to no interaction from the First Responder to operate.

IS4S Awarded Phase II SBIR to Develop Communications Hub
Auburn, AL

The Department of Homeland Security (DHS) awarded IS4S a Phase II SBIR contract to develop the Next Generation First Responder Communication Hub. As technology advances, First Responders are presented with a growing suite of increasingly sophisticated sensors and communication tools that provide vital, up-to-the-minute situational awareness information about their surroundings, location and status of nearby First Responders, and personal well-being. Additionally, an array of communication systems and devices is presented to the First Responder. IS4S will develop an intelligent communications interface that interconnects the variety of sensors and electronics worn or carried by a First Responder with multiple communication systems. This is a central device that efficiently, securely, and resiliently routes incoming and outgoing information to the chosen destination using the best available communication medium. The communications hub will improve efficiency and effectiveness of information transmission while removing the burden of constantly communicating low-level but critical data, thus allowing First Responders to focus on the task at hand. IS4S is working with Gwinnett County Fire Department to get user input into the design process and feedback from testing.

IS4S Awarded Phase II SBIR to Develop Dismount Navigation Kit
Auburn, AL

AFRL awarded IS4S a Direct-to-Phase II SBIR to develop a handheld navigation kit for use in GPS-challenged environments. When GPS is not available, the system will provide the warfighter with an accurate PNT solution, including an accuracy estimate, using inertial-based pedometry, vision, and RF ranges to other warfighters and military platforms. PNT and accuracy will be displayed on an Android End User Device (EUD). This data will be output in standard formats, such as NMEA. All additional components will be designed to be lightweight, have minimal intrusion to the warfighter, and capable of operating for at least 8 hours.
