摘要： A method involves determining, at a mobile device or a service, an uncertainty in height above a reference altitude, an estimated 2D position of the mobile device, and an uncertainty in terrain height above the reference altitude using the estimated 2D position. An uncertainty in height above terrain, of the mobile device, is determined at the mobile device or a server using the uncertainty in height above the reference altitude and the uncertainty in terrain height above the reference altitude.

摘要： Techniques are provided for integrating GNSS measurements between two or more GNSS receivers. An example method includes determining an antenna baseline vector based on relative locations of a first antenna that is communicatively coupled to a first GNSS receiver and a second antenna that is communicatively coupled to a second GNSS receiver, determining a first position estimate and a first integer ambiguity resolution (IAR) status with the first GNSS receiver at a first time, determining a second position estimate and a second IAR status with the second GNSS receiver at approximately the first time, computing a horizontal offset value based on the antenna baseline vector and a difference between the first position estimate and the second position estimate, and generating the wrong fix indication in response to the first IAR status being fixed, the second IAR status being fixed, and the horizontal offset value being greater than a threshold value.

摘要： A jobsite computer network has a local server connectable to a remote server via the internet, a network access transceiver connected to the local server, and a wireless device in wireless communication with the network access transceiver. The network access transceiver receives a message from the wireless device and sends a message to the local server. The local server utilizes information from the message to determine the location of the wireless device. The network access transceiver and/or the wireless device generate data which is sent to the remote server.

摘要： Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) determines a first zone identifier (ID) corresponding to a first zone in which the transmitter UE is located, determines a distance threshold based on a distance requirement of an application associated with the transmitter UE, determines a second zone ID based on the first zone ID, the distance threshold, a size of the first zone, or any combination thereof, and transmits the second zone ID and the distance threshold to one or more receiver UEs. In an aspect, the receiver UE receives the second zone ID and the distance threshold, determines a distance between the receiver UE and the transmitter UE based on the second zone ID and a location of the receiver UE, and transmits, based on the distance being less than the distance threshold, a feedback message to the transmitter UE.

摘要： Based upon the current position of a vehicle, a processor determines which V2X communication standard to use. If a change from a current V2X protocol being used to a new protocol (required because of the location of the vehicle) is determined, software for the new protocol is loaded to re-configure the processor or other electronic devices in the VCU or elsewhere in the vehicle.

摘要： An indoor positioning method based on image visual features is disclosed. A Wi-Fi signal strength value of a Wi-Fi tag is matched with a signal strength list to obtain a first location of a first Wi-Fi tag with the greatest matching degree. A SURF descriptor of an image of the Wi-Fi tag is matched with SURF descriptors recorded in the signal strength list to discover an image of a Wi-Fi tag with the greatest matching degree, thereby obtaining a second location of a second Wi-Fi tag corresponding to the image of the Wi-Fi tag with the greatest matching degree. A three location of a three Wi-Fi tag is obtained according to a homography matrix corresponding to the image of the Wi-Fi tag with the largest matching degree. Positioning information of the mobile device is obtained according to the first location, the second location and the third location.

摘要： Disclosed are techniques for performing wireless communication. In some aspects, a wireless communication device may determine that a prospective position of the wireless communication device is in a geographic area associated with a deficient global navigation satellite system (GNSS) signal. In some cases, the wireless communications device can transmit a sidelink synchronization signal to at least one user equipment (UE) device that is located within the geographic area associated with the deficient GNSS signal.

摘要： Authentication method and systems using RFID-enabled payment cards are disclosed herein where a server receives a request corresponding to authorization of a payment associated with a payment card from an electronic terminal. The server identifies an electronic device of a user associated with the payment card. The server then transmits an instruction to the electronic device to cause an RFID reader of the electronic device to determine whether an RFID tag corresponding to the payment card is located within a predetermined proximity to the electronic device. When the payment card is located within the predetermined proximity, the server executes a first authentication protocol. Moreover, when the payment card is not located within the predetermined proximity, the server executes a second authentication protocol, wherein the second authentication protocol is more restrictive than the first authentication protocol.
