Our Expertise
TruNav is a US-based engineering company that spun off from Illinois Institute of Technology. TruNav provides research, development, products, and technical consultancy in the field of GNSS, sensor fusion, and navigation technologies. TruNav’s engineer have extensive experience in high accuracy and high integrity GNSS systems, Inertial Navigation Sensors (INS), sensor fusion, fault detection and mitigation, and are highly regarded as experts in the navigation field.
 

UNMANNED AIRCRAFT NAVIGATION AND

SENSE & AVOID

 TruNav personnel have developed new navigation solutions for Unmanned Aircraft Systems (UAS) that ensures safe navigation beyond line of sight. These includes detect and avoid integrity and continuity risk evaluations to set quantifiable and certifiable safety requirements on UAS onboard sensors.

INS-AIDED FAULT DETECTION & EXCLUSION

TruNav Engineers have exploited differential GNSS/INS tightly-coupled integration to enhance integrity and robustness of safety-critical navigation applications. TruNav developed innovative, yet certifiable algorithms that optimally fuse inertial sensors with GNSS receivers to have a superior performance in fault detection, anti-spoofing, and jamming resistance for aviation integrity and continuity.  

AIRCRAFT PRECISION APPROACH AND LANDING

TruNav engineers have developed 

advanced navigation algorithms for precision approach applications that involve safety-of-life. Our team has an extensive experience in positioning integrity monitoring for the Ground Base Augmentation Systems (GBAS) sponsored by the Federal Aviation Administration (FAA). These includes dual multi-constellation Advanced Receiver Autonomous Integrity Monitoring (ARAIM).

Relative Navigation

TruNav personnel have special expertise in differential code and carrier navigation for precise inter-vehicle positioning. Applications include mission critical aviation applications that require both high accuracy and high integrity such as autonomous airborne refueling (AAR) and shipboard landing. Our team is extensively involved in relevant applications for the needs of the U.S. Navy. 

 

WAAS/CORS/RTKGEOTAGGING

TruNav develops seamless technology for network-based navigation exploiting Wide Area Augmentation Systems (WAAS), Continuously Operation Reference Stations (CORS), and Real-Time Kinematics networks. These are leveraged to provide centimeter-level accuracy geo survey and monitoring applications. 

ACCUTRACE

AccuTrace is a TruNav product, self-contained sub-centimeter positioning platform, originally developed for NOAA to be used in its National Water Level Network service. It implements advanced Kalman Filter-based GNSS carrier phase positioning, detection and exclusion algorithms. Its accuracy has been validated nation-wide using  existing CORS stations installed in US.   

STRUCTURAL MONITORING

Accutrace can be used 

for structural deformation, health monitoring, and structural-failure early warning systems. AccuTrace's detection capability has been tested on two Chicago bridges in collaboration with Illinois Department of Transportation.  

 

AUTONOMOUS CAR SAFETY

TruNav’s expertise can be applied in building robust navigation systems for cars, truck platooning. TruNav's personnel has extensive experience in multipath mitigation in urban environment  and integrity of self-driving ground vehicles.

RAILWAY INTEGRITY & DEFORMATION INSPECTION

TruNav's expertise can also be applicable in high accuracy and integrity navigation system for high-speed trains. The integrated INS/GNSS navigation solution can provide a precise high frequency positioning even in the existence of temporary GNSS blockages (tunnels, trees). It can also potentially be used for railway track deformation monitoring and maintenance purposes.
