Non-GPS Navigation for Security Personnel and First Responders

Non-GPS Navigation for Security Personnel and First Responders

This paper introduces a “Personal Dead-reckoning” (PDR) navigation system for walking persons. The system is useful for monitoring the position of emergency responders inside buildings, where GPS is unavailable. The PDR system uses a six-axes Inertial Measurement Unit attached to the user’s boot. The system’s strength lies in the use of a technique known as “Zero Velocity Update” (ZUPT) that vi...

Non-GPS Navigation for Emergency Responders

This paper introduces a novel navigation system for walking persons. The system is of particular benefit for emergency responders, who often have to enter and move around in large structures where GPS is unavailable. We refer to our system as “Personal Odometry System” (POS). The POS measures the position of a walking person relative to a known starting position, such as the entrance to a build...

Indoor Navigation for First Responders: A Feasibility Study

GPS/IMU Navigation and Simulation for Higher-Than-GPS Orbits

NAVSYS Corporation has modified its software GPS receiver (SGR) and built an engineering development unit of the High-gain Advanced GPS Receiver (HAGR) optimized for GPS tracking in an orbital environment. Enhancements to the SGR include the ability to track both direct GPS signals, as well as weaker GPS sidelobes. This requires digital beam steering and beam nulling to increase gain towards th...
