According to an embodiment, a communication apparatus acquires tag data of each wireless tag at a plurality of positions of a moved antenna via an antenna and inputs the tag data into a learned model. The communication apparatus acquires, on the basis of the input of the tag data of each wireless tag into the learned model, data indicating a level regarding the range in which each wireless tag is present from the learned model. In addition, the communication apparatus controls, in a case where the levels of the plurality of wireless tags acquired on the basis of one or more measurement processes for a plurality of wireless tags do not satisfy a condition, a measurement process involving a change of a measurement aspect with respect to the plurality of wireless tags.

The present invention discloses a APNT service positioning and integrity monitoring method and system. The method includes the following steps: determining a positioning accuracy requirement in a target scene; when the positioning accuracy requirement is high-accuracy positioning, determining a position of an aircraft by adopting a combined positioning algorithm, and monitoring the integrity of a combined positioning by adopting a multi-solution separation mode; when the positioning accuracy requirement is low-accuracy positioning, judging whether the aircraft is a high-altitude user; if not, adopting an air-to-air positioning algorithm for a high-altitude user and a low-altitude user based on LDACS to determine the position of the aircraft, and adopting a least square residual method to monitor the integrity of the air-to-air positioning. According to different requirements of users on positioning accuracy and actual application conditions, the present invention can provide a variety of APNT alternative solutions for an aircraft.

Methods and systems are provided for clinicians in a medical environment to remotely assess the status of an asset without physically going to the specific place where the asset is located. By using sensors and special purpose rooms, the methods and systems provide an accurate view of what is going on with the asset. Furthermore, the methods and systems can be extrapolated to a patient's status (knowing if the patient is asleep or awake, or when the patient wakes up post anesthesia—this would imply that the patient wears a tag).

A system for tracking the location of an electronic device includes an electronic device and a wireless location tag. The wireless location tag includes a microcontroller unit, and a modular connector interface configured to be communicatively coupled to a port of the electronic device. The wireless location tag is configured to establish an Internet connection to one or more backend electronic devices in response to detecting that the wireless location tag has been communicatively coupled to the port of the electronic device, obtain identifying information that is associated with the electronic device, and identify tag identifying information associated with the wireless location tag. The wireless location tag is also configured to send one or more instructions to the one or more backend electronic devices via the Internet connection, and send one or more ping messages to the one or more backend electronic devices.

The present invention relates to a mobile terminal and a method for controlling the same, the mobile terminal including a location information module configured to acquire location information related to the mobile terminal based on one of a first positioning method that is configured to detect access points (APs) adjacent to the mobile terminal, receive location information related to the detected APs, and acquire the location information on the mobile terminal based on the received location information related to the APs, and a second positioning method that is configured to receive location information related to the detected APs and other APs located within a predetermined area where the detected APs are located, and acquire the location information on the mobile terminal based on the received location information related to the APs, a communication unit configured to perform wireless communication with a first positioning server providing first AP information including the location information related to the detected APs or a second positioning server providing second AP information including the location information related to the detected APs and the other APs located within the predetermined area where the detected APs are located, a memory configured to store the first AP information or the second AP information, and a controller configured to perform a process of acquiring the location information on the mobile terminal according to the second positioning method for a preset time when the APs located adjacent to the mobile terminal are detected, and acquire the location information on the mobile terminal according to the first positioning method when the location information on the mobile terminal is not acquired for the preset time.

A quick positioning method and a vehicle-mounted system are disclosed. The quick positioning method includes: acquiring position information from an external positioning terminal the same time when the vehicle-mounted system is started, and determining continuously whether position information is available from a local GPS positioning module; and using the position information acquired from the external positioning terminal until position information is available from the local GPS positioning module. By the above method, there would be available position information before the GPS module of the vehicle-mounted system is fully activated, thus effectively enhancing the positioning efficiency of the vehicle-mounted system.

Disclosed herein is a method for measuring a position. The method for measuring a position includes: determining a GPS satellite visible area and a GPS satellite invisible area depending on whether or not an area is an area in which a predetermined number or more of GPS satellites are observable; measuring a position of a moving object on the basis of a first position measuring scheme using GPS satellites in the case in which the moving object enters the GPS satellite visible area; and measuring the position of the moving object on the basis of at least one of the first position measuring scheme and a second position measuring scheme other than the first position measuring scheme in the case in which the moving object enters the GPS satellite invisible area.

In accordance with some embodiments, a system includes a line locator and a device configured to communicate through an internet with a server also coupled to the internet. Furthermore, a plurality of line locate transmitters are distributed geographically and configured to communicate through the internet with the server. The server operates to activate one of the plurality of line locate transmitters based on a geographic location of the device.

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 vehicle, for example, an autonomous vehicle performs localization to determine the current location of the vehicle using different localization techniques as the vehicle drives. The localization technique used by the autonomous vehicle is selected from a localization variant index that stores mapping from a driving context to localization variant, each localization variant identifying a localization technique. The driving context may comprise information including: a geographical region in which the autonomous vehicle is driving, a speed at which the autonomous vehicle is driving, an angular velocity of the autonomous vehicle, or other information. Using an optimal localization technique in each driving context improves the accuracy of localization as well as computing efficiency of the process of localization.
