Products and Innovations of Advanced Navigation

High-Performance and Compact Inertial Sensors

Advanced Navigation is a leading manufacturer of highly accurate micro-electromechanical system (MEMS) and fiber-optic gyroscopes (FOG) inertial measurement units (IMU) and attitude and heading reference systems (AHRS) for industrial and tactical use. These systems are rigorously temperature-calibrated and offer a 1000 Hz output rate for exceptional performance.

Their FOG solutions (Boreas A70 and Boreas A90) provide even higher accuracy with bias instability as low as 0.001°/hr and roll and pitch accuracy as high as 0.005°. Advanced Navigation's Vertical integration ensures precise hardware and software control, setting a new benchmark for accuracy and reliability in motion sensing and orientation.

MEMS IMU Solutions

The MEMS-based IMU / AHRS range shares a common communication protocol, allowing customers to upgrade or downgrade their product range without costly re-engineering.

FOG IMU Solutions

The fiber-optic gyroscope (FOG) IMU/AHRS solutions offer navigation, strategic-grade accuracy, and rapid north-seeking capabilities that don't depend on GNSS.

Application: Orientus AHRS in Quix Exoskeleton

The IHMC Robotics Lab is developing the Quix, a robotic exoskeleton prototype, to empower paraplegics to stand and walk, greatly enhancing their mobility, independence, and overall well-being. However, creating a motorized exoskeleton with precise control is challenging, especially when dealing with eight powerful motors.

The Orientus AHRS offers a solution by supplying real-time data on roll, pitch, and yaw, essential for maintaining the exoskeleton's balance and direction. In addition, the Orientus's compact size facilitates seamless integration into the Quix exoskeleton's mechanical framework.

Acoustic Inertial Navigation Systems for Subsea Exploration

Advanced Navigation specializes in underwater acoustic positioning solutions, prioritizing high performance while minimizing size, weight, power consumption, and cost (SWaP-C). Their Subsonus technology offers a compact and efficient ultra-short baseline (USBL) positioning system featuring AI-based acoustic processing and a top-notch hydrophone array.

They also provide Subsonus Tag, an advanced acoustic transponder with pressure-tolerant electronics and wireless charging that can operate at 2000m without expensive pressure vessels. For enhanced performance, the USBL2 configuration offers unmatched accuracy and heading information without relying on magnetic compasses, setting Advanced Navigation apart in the field.

Application: Subsonus USBL2 Technology Accelerates JM Robotics Underwater ROV Program

JM Robotics needed to design a compact ROV for precise underwater pipeline inspection in shallow and challenging conditions. They integrated Subsonus in a USBL2 configuration to obtain accurate navigation, heading, and position data in challenging environments. This solution allowed for efficient and cost-effective inspections, improved ROV piloting, and safeguarded against collisions in resource extraction applications.

AI-Driven Inertial Navigation Systems

Advanced Navigation offers MEMS and FOG-based systems for precise navigation in challenging conditions. They combine temperature-calibrated sensors, including accelerometers, magnetometers, gyroscopes, and pressure sensors, with advanced RTK GNSS receivers and an AI-based algorithm, optimizing performance while minimizing Size, Weight, Power Consumption, and Cost (SWaP-C).

Their AI algorithm swiftly corrects sensor errors and improves accuracy through dynamic constraints and physics models, outperforming traditional Kalman filters. These systems support multiple satellite constellations (GPS, GLONASS, GALILEO, BeiDou, and QZSS), operate at 1000 Hz, and cover various performance grades (industrial, tactical, navigation and strategic), simplifying client choices.

FOG GNSS/INS Solutions

The innovative DFOG INS offers strategic-grade performance with a 40% reduction in size and cost compared to similar products. These INS solutions use a common communication protocol for easy product range expansion without re-engineering.

Application: Certus Evo - A Game-Changer for Safe Drone Retrieval in Contested Environments

Precision flight control and navigational accuracy are essential in addressing the challenge of accurate and safe in-flight drone retrieval, particularly in defense applications. This is exemplified by the U.S. defense sector's active pursuit of a solution to launch and retrieve a significant quantity of small unmanned air systems (UAS) drones from combat aircraft, keeping a safe distance from adversary defenses.

For this initiative, Dynetics was selected by the Defense Advanced Research Projects Agency (DARPA) to use drones for complex operations in contested environments. Dynetics chose the Advanced Navigation Spatial Dual (now Certus Evo), which allowed for high-accuracy position data through Kinematica post-processing. The Spatial Dual's performance and data analysis capabilities convinced Dynetics to integrate it into their final recovery system design.

"The Spatial Dual units performed nicely and provided very useful data for post-flight analysis. The Spatial Dual performance during early flight tests, combined with low power consumption and small form factor, convinced us to make the Spatial Dual part of the final recovery system design." Bill Martin, lead engineer at Dynetics.
