Abstract: A geo-containment system includes at least one unmanned vehicle and an enforcement system that is onboard the unmanned vehicle and configured to limit travel of the unmanned vehicle based, at least in part, on predefined geospatial operational boundaries. Such boundaries may include a primary boundary and at least one secondary boundary that is spaced apart from the primary boundary a minimum safe distance. The minimum safe distance is determined while the unmanned vehicle is traveling. The minimum safe distance is determined using state information of the unmanned vehicle and/or dynamics of the unmanned vehicle. The state information includes at least position and velocity of the unmanned vehicle. The enforcement system is configured to alter and/or terminate operation of the unmanned vehicle if the unmanned vehicle violates the primary geospatial operational boundary and/or the secondary geospatial boundary.

Abstract: A device and method which improves the accuracy of a global positioning system (GPS)-equipped mobile device. A time-stamped first set of GPS data is received via a GPS receiver, e.g., of the base station. A second set of GPS data describing a geoposition of the mobile device is received from the mobile device by the base station. A time of collection of the GPS data coincides. The GPS data includes code, carrier-phase, and pseudo-range information from each of the GPS satellites. A predetermined GPS position correction technique is used to generate a first corrected geoposition of the mobile device using the GPS data. Corrected, carrier-smoothed geoposition is generated as a second corrected geoposition using a carrier smoothing operation. The second corrected geoposition is transmitted to the mobile device and/or an external response system such as a drone or first responder.

Abstract: A method may be executed by a base station or mobile device to improve accuracy of a global positioning system (GPS)-based position or “geoposition” of the mobile device. A time-stamped first set of GPS data may be received via a GPS receiver, e.g., of the base station. A second set of GPS data describing a geoposition of the mobile device is received from the mobile device by the base station. A time of collection of the base station and mobile device GPS data coincides. The GPS data includes code phase and pseudo-range data from each of the GPS satellites, and may include carrier phase data. A predetermined GPS position correction technique is used to generate a corrected geoposition of the mobile device using the GPS data.

Abstract: A Geo-containment system includes at least one unmanned aircraft and a control system that is configured to limit flight of the unmanned aircraft based, at least in part, on predefined Geo-spatial operational boundaries. These boundaries may include a primary boundary and at least one secondary boundary that is spaced apart from the primary boundary a minimum safe distance. The minimum safe distance is determined while the unmanned aircraft is in flight utilizing state information of the unmanned aircraft and dynamics and dynamics coefficients of the unmanned aircraft. The state information includes at least position and velocity of the unmanned aircraft. The control system is configured to alter or terminate operation of the unmanned aircraft if the unmanned aircraft violates the primary Geo-spatial operational boundary or the secondary Geo-spatial boundary.
