A magnetic beacon and inertial sensor system for precise indoor localization is provided using active magnetic beacons, magnetometers and inertial measurement units. The system is designed to work in environments that are not conducive to radio frequency (RF) (such as GPS, cell, Wi-Fi, or Bluetooth) or optical techniques (CCTV, IR), such as inside heavy industrial plant settings, underground or underwater.

Systems and methods for beacon device fleet management are provided. One example system includes a plurality of beacon devices, a plurality of mobile computing devices, a fleet management system, and a fleet owner computing devices. One example method includes receiving, by the fleet management system, a device status request from the fleet owner computing device. The fleet management system determines one or more operational statuses of beacon devices owned by the fleet owner and transmits data indicative of the one or more operational statuses to the fleet owner computing device. The operational statuses can include a current detection status (e.g., online or offline), a location status, a power source status, and/or other operational parameters.

An improved aviation transponder is discussed herein. The improved aviation transponder demonstrates improved cohabitation and survivability characteristics, allowing the transponder to be placed near other antennas without causing or receiving interference, and reducing potential damage caused by high-energy electromagnetic fields, such as those experienced near an air traffic control (ATC) or military radar installation. Additionally, a small form factor of the transponder results in a smaller, more compact aircraft that consumes less energy, reduces heat dissipation, and maximizes battery life and/or flight time. The transponder may comply with modular interface standards, and may include a radio configured for transmitting 200-watt signals. Based at least in part on the improved performance, the transponder can be implemented in unmanned aerial vehicles (UAVs), for example.

Systems and methods for navigating an aerial vehicle are provided. One example aspect of the present disclosure is directed to a method for navigating an aircraft. The method includes receiving, by one or more processors, one or more first geographic coordinates via an interface configured to receive geographic coordinates from a satellite transmission. The method includes receiving, by the one or more processors, one or more second geographic coordinates via an interface configured to receive geographic coordinates from a ground transmission. The method includes determining, by the one or more processors, that the one or more first geographic coordinates and the one or more second geographic coordinates are inconsistent. The method includes updating, by the one or more processors, a flight plan using the one or more second geographic coordinates when the one or more first geographic coordinates are inconsistent with the one or more second geographic coordinates.

A communications system for emergency personnel comprising a plurality of beacons disposed in a building or large structure, wherein each beacon is placed in a location such that it can communicate with at least its next nearest beacon when activated and/or nearby emergency personnel. Each beacon comprises a low power consumption PCBA, a battery, and a housing. Each beacon is installed in the building or large structure prior to a disaster incident or emergency event.

During an evacuation situation in a building that is equipped with an elevator system and in which a plurality of fixed point markers are arranged at defined sites, an escape route is transmitted to a person by means of a mobile device. The fixed point markers store data that can be received by the mobile device. An instantaneous position of the mobile device can be determined when the mobile device uses data received from a fixed point marker to access a database in which the data is linked to a site of the fixed point marker. The ascertainment of the escape route to a destination is based on the instantaneous position of the mobile device. The person is registered on reaching the destination when the mobile device is detected at the destination.
