Wearable Performance Assessment System
Army
Wearable Performance Assessment System (WPAS) and accompanying computational models detect and classify soldier relevant complex, highly-dynamic tasks in real-time. The WPAS consists of a scalable set of unobtrusive body-warn biomedical sensors called Kinetic Pods (KP) that provides accurate detection of soldier movements. The sensors are small, low-cost, and capable of wirelessly transmitting raw and processed sensor data to a central end user application. The WPAS is capable of operating in indoor and outdoor environments. The WPAS will automatically process high volumes of biomechanical data, identify and tag a set of complex motions from a larger set of free-form motion data, and monitor subjects in real-time in a cost-effective manner. The system is scalable, upgradable, and features an open architecture. The set of motions and tasks that can be identified with WPAS is diverse. It includes, but is not limited to, obstacle course negotiation, terrain navigation, and tactical movements in addition to simpler motions such as standing, sitting, walking, and crawling. Yotta Navigation personnel have extensive experience in this area. This effort is led by a US Army veteran and builds on Yotta Navigation’s patented motion detection and classification algorithms.
Mobile Activity Tracking System (MATS)
Air Force
A compact, rugged, reliable, and cost-effective Mobile Activity Tracking System (MATS) is developed for military simulations and field training exercises (FTX). MATS consists of wearable Human Motion Trackers (HMT) modules usable over long-duration training missions both indoors and outdoors, and either with or without GPS access. The HMT can securely communicate warfighter location and activity information in real-time with multiple other types of devices. In addition, HMT uses an extensible open architecture approach which allows for multiple options and configurations based on user needs. A robust DIS interface is included. The core HMT technology has been proven in many urban and field settings. MATS builds on many years of experience building dismounted navigation systems for the US Army, Navy Special Warfare (SEALs), and the Intelligence Community (IC). Yotta Navigation worked with AFRL and AFSOC stakeholders to tailor HMT with the most desired features for their live, virtual, and constructive (LVC) training.
Secure GPS Sensor Platform (GPS-SP) for Handheld CE
Army
Yotta Navigation developed and built a simple, rugged, reliable, compact and cost-effective military GPS sensor platform (GPS-SP). The GPS-SP is a self-contained military Positioning, Navigation, and Timing (PNT) module. It securely communicates with the Android operating system platform, which is planned for use in the new US Army Handheld Computing Environment (Handheld CE). This decouples the GPS receiver from the handset, allowing each technology to evolve separately, while still ensuring standards-based data-centric interoperability between them. The result is a more open-architecture approach, enabling flexibility, innovation, and cost-savings over the current DAGR-centric military GPS paradigm. In addition, the GPS-SP is versatile enough to allow secure connections to other sensors, and will have a natural migration path to future MGUE M-Code receivers. Our previous experience integrating SAASM PPS P(Y) GPS receivers, along with prior work on Android and other embedded/real-time operating systems, has informed the design of this platform.
Intelligent Human Motion Detection Sensor
Army
Yotta Navigation continues developing a robust capability to determine human motion in GPS denied environments. Testing showed that it is possible to achieve 95% motion detection accuracy. This capability significantly improves a warfighters ability to accurately navigate under difficult tactical conditions. Both a software and a hardware solution is provided. The software consists of a portable library for embedded devices, and a standalone application (App) for use on Linux/Android handheld devices. The hardware comprises of upgrades to the existing MOUTman, a rugged, secure, compact, high-precision real-time human motion detection sensor and navigation aid. The MOUTman system takes advantage of Yotta Navigations existing expertise in several areas: hardware development, inertial navigation, user interface, COTS component integration, and a deep knowledge of real-time systems. This solution also features innovative security and communication capabilities. The system is expandable and can incorporate new sensors, user interface, and input/output devices as they become available. Yotta Navigation's approach provides reliable motion detection, positioning, attitude (orientation), and altitude (elevation) data, all in the total absence of GPS.
Alternative PNT Augmentations for Handhelds
National Geospatial Intelligence Agency
Yotta Navigation developed a proof-of-concept version of the MOUTman, envisioned to be a rugged, secure, high-precision, handheld real-time navigation system suitable for military operations. This system took advantage of Yotta Navigation expertise in several areas: inertial and GPS-assisted navigation, user interface design, efficient integration of components from mainstream suppliers, and a deep knowledge of real-time systems. Yotta Navigation provides improvements to the original MOUTman design in several areas: sensor integration, algorithm improvement, communication, mapping, and the use of military GPS. The primary tracking device continues to use recent advances in commercial-off-the-shelf (COTS) Micro-Electro-Mechanical Systems (MEMS) technologies.
High Data Rate Acoustic Communication
Navy
Building on the success of its Dolphin acoustic transceiver system, Yotta Navigation Corporation designed and built an ultrasonic acoustic modem capable of sending information through ocean acoustic channels at extremely high bit rates of 500 kbps to 1 Mbps over ranges from 10 to 100 meters. The device is compact, reliable, and maximizes use of proven COTS components. Historically, there have been significant obstacles to achieving this objective, particularly at a reasonable cost and size needed to fit within a AUV/UUV form factor. However, Yotta Navigation has shown both through simulation and through modifications to an existing Dolphin system that this is achievable. We have identified and evaluated an initial set of updated hardware components including converters, signal processors and transducers for use.
Naval Special Warfare (NSW) Underwater Secure Text Messaging and Diver Locater
Navy
Yotta Navigation and The Ohio State University developed a complete diver text messaging and locator system. The system securely transmits preformatted and free-text messages, and accurately determines range and bearing, at distances of up to 1000 meters. This system consists of two major components. A multimode receiver and transmitter, mounted on a swimmer delivery vehicle or similar platform, serves as a central node. This central node both communicates with and determines the location of individual divers on the system's acoustic data network. Individual divers carry a small portable device which contains an integrated miniature inertial navigation system, an ultrasonic transducer for communication, as well as a full-color graphical user interface. The system builds on previous research and development work conducted by Yotta Navigation, and takes advantage of the substantial modeling, simulation, and test capabilities developed by Ohio State University. Extensive field testing demonstrated that the challenging requirements for this project were met.
