A positioning support device transmits radio signals using at least one default configuration parameter value. A mobile device measures characteristics of the signals at different locations. An apparatus assembles, based on the measured characteristics and indications of the locations of measurement, data which enables a determination of characteristics of radio signals transmitted by the positioning support device, which are expected to be observable at different locations. The apparatus determines in addition at least one adapted configuration parameter value and causes the positioning support device to store the assembled data for future transmissions and to use the at least one adapted configuration parameter value for future transmissions. As a result, the positioning support device transmits radio signals including the stored data using the at least one adapted configuration parameter value.

Systems and methods for improved geolocation in a low power wide area network are disclosed. One example method may include receiving an instruction to determine a geolocation of an end in a low power wide area network. An instruction may be transmitted to the end node for the end node to transmit a high-energy geolocation signal at a power of about 0.5 Watt to about 1 Watt. The end node may transmit the high-energy geolocation signal and a plurality of gateways of the low power wide area network may receive the high-energy geolocation signal. A plurality of receipt times may be identified. Each receipt time may be indicative of the time at which the high-energy geolocation signal was received by the respective gateway of the plurality of gateways. Based at least in part on the plurality of receipt times, a geolocation of the end node may be determined.

A method for locating an animal using radio waves. In radiolocation, a large number of possible calculation results for the location of the animal arise. Using the results of previous measurements and calculations with regard to the possible locations of the node to be located, stochastic calculations are used to filter out, from the plurality of the current location calculation results, that result which in fact applies with the highest probability. Acceleration values which are measured at the animal are used in the stochastic calculations. It is assumed that with increasing measured acceleration values the probability increases that there can also be relatively large distances between temporally successive locations of the node to be located.

A system and method are provided for navigation correction assistance. The method provides a vehicle with a camera and an autonomous navigation system comprising a navigation buoy database and a navigation application. The navigation application visually acquires a first navigation buoy with an identity marker and accesses the navigation buoy database, which cross-references the first navigation buoy identity marker to a first spatial position. A first direction marker on the first navigation buoy is also visually acquired. In response to visually acquiring the first direction marker, a first angle is determined between the camera and the first spatial position. A first distance may also be determined between the vehicle and the first navigation buoy using visual methods or auxiliary position or distance measurement devices. Then, in response to the first spatial position, the first angle, and the first distance, the spatial position of the vehicle can be calculated using trigonometry.

A delivery device includes an image capture device for generating delivery image data of a delivery at a service address. A processor executes a delivery application to bidirectionally communicate delivery data with the delivery data server via the network interface, wherein the delivery data includes a delivery tracking number and the delivery image data. The delivery data server processes the delivery data to provide a delivery confirmation to a customer at the service address, wherein the delivery confirmation includes the delivery tracking number and the delivery image data.

A position tracking system includes an array of detection pixels coupled to a head-mounted display (HMD) configured to capture light signals reflected from an environment surrounding the HMD. The position tracking system maintains, in a database, signal data related to a plurality of positions of the HMD. The position tracking system determines signal data related to a position of the HMD, based on the light signals captured during a time instant of the position of the HMD. The position tracking system matches the determined signal data to the maintained signal data, determines a present position of the HMD based on the matching, updates position data of the HMD with the determined position, and provides the updated position data of the HMD.
