摘要： The accuracy of the location estimate of a Wireless Location System is dependent, in part, upon both the transmitted power of the wireless transmitter and the length in time of the transmission from the wireless transmitter. In general, higher power transmissions and transmissions of greater transmission length can be located with better accuracy by the Wireless Location System than lower power and shorter transmissions. Wireless communications systems generally limit the transmit power and transmission length of wireless transmitters in order to minimize interference within the communications system and to maximize the potential capacity of the system. Several methods meet the conflicting needs of both systems by enabling the wireless communications system to minimize transmit power and length while enabling improved location accuracy for certain types of calls, such as wireless 9-1-1 (emergency) calls. Such methods include mobile-assisted techniques in which the mobile unit includes functionality to assist in improving location accuracy. The WLS locates the transmitter (mobile unit) while the latter is using a modified transmission sequence comprising a message sent from the wireless transmitter using transmission parameters different from the normal transmission parameters broadcast on the forward control channel by the base stations in the associated wireless communications system. A trigger event, such as the user dialing 9-1-1, causes the mobile unit to operate in the mode in which the modified transmission sequence is used.

摘要： A system (10) and method delivers simplex signals (26, 28) to a communication unit (24) located within an area (20) (e.g., a building) where an obstruction exists between the signal transmitter (12, 18) and the communication unit (24). The system (10) uses an infrastructure retransmission apparatus (14, 16, 22) to receive (204, 304, 402, 404) the signals (26, 28) and retransmit (208, 310, 410) them within the area (20). Geolocation signals (26) from navigation satellites (12) can be retransmitted (208, 310) using the infrastructure retransmission apparatus (14, 16, 22), thus enabling a communication unit (24) located within an obstructed area (20) to calculate its position.

摘要： A multilateration location system (12) includes a locatable unit (16) and any number of known-position locators (14). A time of arrival detector (22) determines instants in time when a location signal (20) transmitted by the locatable unit (16) arrives at various known-position locators (14). For each combination of two known-position locators (14) that receive the location signal (20), a pre-estimation process (32) determines whether the difference in arrival times is less than or equal to a maximum propagation duration for the locator pair. The maximum propagation duration is based upon the distance between the locators (14) in the locator pair. If the difference is greater than the maximum propagation duration, the difference is omitted from the data set processed by a multilateration calculation process (34). A post estimation filtering process (36) screens out location estimates that are too distant from a predicted position.

摘要： An apparatus and system of user equipment (UE) location determination using Transmission-Reception Points (TRPs) are described. Uplink angle of arrival (UL-AoA). UL relative time of arrival (UL-RTOA), and/or UL sounding reference signal reference signal received power (SRS-RSRP) measurements use an UL Antenna Reference Point (ARP) identifier (ID), which is associated with a UL ARP location (TRP panel) that is relative to the TRP geographical coordinates. The Location Management Function (LMF) requests additional path reporting for UE positioning for downlink Time Difference of Arrival (DL-TDOA), UL-TDOA, and multi-round trip time (RTT) reporting. The additional path information includes relative time difference and path quality indicator values and possibly a path RSRP value. The LMF indicates a maximum number of additional paths to be reported. The expected value and uncertainty range for each TRP is reported for downlink angle of departure (DL-AoD) measurements.

摘要： A positioning method using images and radio waves may include: estimating a distance and an angle from the positioning reference node to a positioning target terminal; identifying an obstacle or reflective object in a vicinity of the positioning target terminal or on a path between the positioning target terminal and the positioning reference node by using image information on the positioning target terminal at a position estimated by the distance and the angle; estimating an incident angle or a reflection angle of a radio wave signal reflected by the reflective object identified based on the image information; and estimating a position of the positioning target terminal based on the reflection angle and the distance.

摘要： Embodiments provide an unmanned aerial vehicle comprising a receiver and a position determiner. The receiver is configured to receive two periodic wideband signals transmitted from two spaced apart base stations of a navigation system for unmanned aerial vehicles, wherein the two periodic wideband signals are time-synchronized. The position determiner is configured to determine a position of the unmanned aerial vehicle relative to the two base stations based on a difference between reception times of the two periodic wideband signals and based on reception intensities of the two periodic wideband signals.
