An illustrative embodiment disclosed herein is a satellite including a transceiver, a first antenna, a second antenna, and a switch to enable only the first antenna by electrically coupling the first antenna to the transceiver responsive to a satellite constellation having less than a threshold number of satellites and enable only the second antenna by electrically coupling the second antenna to the transceiver responsive to the satellite constellation having greater than the threshold number of satellites.

A Location Management Component (LMC) may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU receives location related messages from any of (i) a UE via a gNB Distributed Units (gNB-DU), (ii) another gNB via an Xn interface, or (iii) a core network entity (e.g. AMF) via an NG interface. These messages can be transported in container messages (e.g., an RRC container for LPP messages sent to or received from a UE; an NGAP container for messages sent to or received from an AMF, or an XnAP container for messages sent to or received from another gNB). The gNB-CU removes the location related messages from the container messages and forwards them to an LMC using F1-AP container messages. Location related messages sent from an LMC to other entities are transported in a reverse manner through a gNB-CU using corresponding container messages.

The present invention relates to wireless localization method and apparatus of high accuracy, and measures strength of at least one signal that is transmitted from at least one fixed node, estimates a relative position of a moving node, generates a change pattern of at least one signal strength according to relative changes in positions of the moving node over a plurality of time points from at least one signal strength and the relative position of the moving node, and estimates an absolute position of the moving node, based on a comparison between the change pattern of the at least one signal strength and a map of a distribution pattern shape of signal strength in a region where the moving node is located. Accordingly, it is possible to accurately estimate a position of a moving node using a radio signal which not only accurately estimates the position of the moving node even in a change of wireless environment but also has almost no change in signal strength over a wide region.

An apparatus for pointing wireless communication antennas may include (1) a mount that secures (A) a wireless communication antenna that transmits wireless communication signals to a remote wireless communication antenna that is secured on a remote mount and (B) an array of pointing antennas that receives, from a remote array of pointing antennas mounted on the remote mount, a beacon signal that indicates a location of the remote array of pointing antennas, (3) a motorized drive that physically orients the mount, and (4) a processing device that (A) determines, based at least in part on the beacon signal, an orientation of a boresight axis of the wireless communication antenna relative to a boresight axis of the remote wireless communication antenna and (B) directs the motorized drive to orient the mount such that the wireless communication antenna's boresight axis aligns with the remote wireless communication antenna's boresight axis.

Disclosed are methods, systems, and non-transitory computer-readable medium for vehicle information reporting of a vehicle using Global Navigation Satellite System (GNSS) receivers and a satellite communication transceiver for a satellite system. For instance, the method may include obtaining GNSS data, the obtained GNSS data being received by the GNSS receivers; storing a portion of the obtained GNSS data in a memory as historical position information; receiving inputs from timers, sensors, or a user interface of the vehicle; determining whether to transmit a message based on rules applied to the obtained GNSS data and the received inputs; in response to determining to transmit the message, compiling the message based on a message content rule, the message including a historical position data message based on the message content rule and the historical position information; and transmitting the message via the satellite communication transceiver to a satellite of the satellite system.

A method, a system, and a computer program product for determining a location of a communication device. Data corresponding to a detected transmission of a data packet between a tag device and one or more communication devices is received on one or more communication channels. At least one of a channel state information and a signal strength associated with the detected transmission for each frequency band in a plurality of frequency bands are determined. Based on the determined channel state information, one or more lengths of signal paths corresponding to the detected transmission of the data packet are determined. A shortest length in across one or more communication devices is selected to determine a location of the tag device.

Embodiments herein relate to a method performed by a first access network node 411, for positioning of a wireless communication device 430. The method comprises obtaining a first and a second information relating to multilateration of the wireless communication device 430. The first information relating to multilateration comprises a first timing advance value, or a first indication of the first timing advance value, associated with the first access network node 411 and the wireless communication device 430, a Temporary Logical Link Identifier (TLLI) corresponding to the wireless communication device 430 and a first identity of a first cell 421, in which first cell 421 the first timing advance was obtained. The method further comprises mapping, based on the TLLI, the associated first and second identities of the first and second cells 421, 422 and the first and second timing advance values to a network layer protocol connection on a first interface 441. The method further comprises transmitting, to a positioning node 413, the first and second timing advance values and the first and second identities of the first and second cells 421, 422. Embodiments herein further relate to corresponding methods in a second access network node 412 and in a positioning node 413.

A method and system for phase shift based time of arrival (TOA) reporting in passive location ranging is herein provided. According to one embodiment, a method includes measuring, by a receiver station (RSTA), a first phase shift time of arrival (PS-TOA); measuring, by an initiator station (ISTA), a second PS-TOA; reporting, by the RSTA, the first PS-TOA, reporting, by the ISTA, the second PS-TOA; broadcasting, by the RSTA, time stamps; and determining, by a passive station (PSTA), a differential distance between the PSTA and a pair of the RSTA and ISTA based on the first PS-TOA, the second PS-TOA, and the broadcast time stamps.

A surface movement, guidance and control system is provided. The system includes a plurality of base stations, disposed at a site, each base station providing a coverage area and having a known geo location and using an IP-based high data rate radio link with low latency. Each base station is adapted to receive periodic positional updates from vehicles on the site over the IP-based high data rate radio link. The system also includes a server. The server is communicatively coupled to the plurality of base stations. The server is configured to track and periodically transmit the location of the vehicles to the base stations. Each base station broadcasts vehicle position information.

An illustrative embodiment disclosed herein is a method, by a satellite, including sending a downlink signal to a first endpoint and a second endpoint at a first time and receiving a first uplink signal from the first endpoint at a second time. The second time is based on a first delay value calculated by the first endpoint. The method further includes receiving a second uplink signal from the second endpoint at a third time. The third time is based on a second delay value calculated by the second endpoint. The method further includes calculating the first delay value and the second delay value based on one or more identifiers of the first endpoint and the second endpoint, respectively, and an algorithm and determining a first distance between the satellite and the first endpoint and a second distance between the satellite and the second endpoint.
