摘要： A self-localizing apparatus uses timestampable signals transmitted by transceivers that are a part of a distributed localization system to compute its position relative to the transceivers. Transceivers and self-localizing apparatuses are arranged for highly accurate timestamping using digital and analog reception and transmission electronics as well as one or more highly accurate clocks, compensation units, localization units, position calibration units, scheduling units, or synchronization units. Transceivers and self-localizing apparatuses are further arranged to allow full scalability in the number of self-localizing apparatuses and to allow robust self-localization with latencies and update rates useful for high performance applications such as autonomous mobile robot control.

摘要： A method performed by a mobile lawn mowing robot includes pairing a beacon with the mobile lawn mowing robot. Pairing the beacon with the mobile lawn mowing robot includes determining a distance between the beacon and the mobile lawn mowing robot and confirming that the beacon is within a pairing distance from the mobile lawn mowing robot based on a comparison of the determined distance to a pairing distance. Pairing the beacon with the mobile robot lawn mowing robot further includes, subsequent to confirming that the beacon is within the pairing distance from the mobile lawn mowing robot, pairing the beacon with the mobile lawn mowing robot, and, following pairing, detecting wideband or ultra-wideband signals from the beacon, and using the wideband or ultra-wideband signals to enable navigation over an area.

摘要： Methods and devices are presented for synchronizing positioning signals in a kinematic location network. In particular, methods and devices are presented for synchronizing a unique positioning signal generated by a positioning-unit device to a reference positioning signal generated by a reference transmitter, where the positioning-unit device and the reference transmitter are moving relative to each other. In certain embodiments the reference transmitter or the positioning-unit device, or both, self-monitor trajectory data comprising one or more of location, velocity or acceleration, e.g. using inertial navigation systems, and broadcast that data in their positioning signals. The trajectory data enables estimation of Doppler shifts and propagation delays associated with the positioning signals, allowing measurement and correction of clock drift for synchronization of the positioning signals.

摘要： This document presents a location tracking system comprising a plurality of location tracking nodes disposed to cover an area where the location tracking is to be carried out, at least one mobile tag configured to communicate with at least one of said plurality of location tracking nodes at a time for location tracking purposes, and a control apparatus configured to control operational parameters of the plurality of location tracking nodes and the at least one mobile tag. The control apparatus and the plurality of location tracking nodes are configured to carry out an automatic calibration phase during operation of the location tracking system the location tracking nodes transmit and receive test signals between the neighboring nodes, and report measurement results to the control apparatus. The control apparatus then optimizes the operation parameters of the location tracking system on the basis of received measurement reports.

摘要： The invention described relates to a radio positioning system primarily for a mobile telephone network, in which a list of offsets in time, phase, frequency, or derivatives thereof, or their equivalents expressed as offsets in distance or derivatives thereof, of a plurality of transmission source signals, received at a given location, relative to a common reference are generated. Data is acquired from one or more receivers, the positions of which may be known or determined. Such data are offsets in time, phase, frequency, or derivatives thereof, respectively of signals received from the transmission sources relative to a reference source in each receiver or to each other. The acquired data is combined for calculating the list of offsets relative to the common reference.

摘要： The invention relates to a determining the position of a mobile receiver 4 in a digital telephone network positioning system. A first receiver 3 is at a known location and others are mobile. The method involves transmitting signals from a plurality of sources 1, the transmission signals having a format at least a portion of which has predetermined values or a portion of which is sequentially repeated. The time offset of the transmission signals received at each receiver 4,5 from the transmission sources 1 relative to each other in the receivers by means for comparing the received transmission signals from the different transmission sources with one another to determine their relative time offsets. The time delay between the respective signals received at both receivers 4,5, is determined to thereby determine the position of the receiver 4.
