摘要： Synchronization of a time base at a local clock to a reference time. Initially, correction data (e.g., synchronization data) may be derived from packet data received over an asynchronous packet-switched network (e.g., the internet). Correction data derived from the packet data may be used to correct at least a portion of the time base (e.g., a frequency component). In turn, once the time base is corrected (e.g., to better than a predetermined quality threshold), the source of synchronization data may change to an alternate (e.g., more accurate source) such as positioning signals from a positioning system. In this regard, the corrected time base may be used to assist in acquiring such positioning signals to allow for higher accuracy correction. Furthermore, use of the positioning system may allow for correction of a phase of the time base (e.g., to align the phase to the positioning system. In turn, an accurate time base may be utilized (e.g., for location determination using the positioning system) and/or other contexts such as a downstream communication operation. For instance, a device employing the synchronization techniques described herein may be an LTE base station used to facilitate downstream communication with another device by use of the synchronized time base.

摘要： An approach to joint processing of GNSS signals to determine a receiver location and common mode bias associated with grouped records corresponding to GNSS signals. In this regard, a receiver may acquire signals from a GNSS space vehicle over a relatively long period of time. In turn, records corresponding to received signals may be stored and grouped. The grouping of records may be based on assumptions of a common-mode bias for certain records (e.g., records acquired within a given duration of an observation time period). Upon acquisition of a suitable number of records, an over-determined system may be established that is used in iterative processing to solve for location and/or bias values associated with the respective common-mode bias for each group of records. As such, improved receiver performance may be realized.

摘要： Location of one or more devices in a monitored environment based at least in part on data communications between a device and a communication array disposed relative to the monitored environment. The communication array may include a plurality of nodes, at least two of which may be in operative communication with a mobile device. The plurality of nodes may be synchronized to a common time base with communications over a packet-switched communication network (e.g., employing IP communications or the like). In turn, communications between nodes of known location and a device may be used to determine ranging values at least in part based on characteristics (e.g., time of flight) of the communication. As such, a location may be determined by, for example, multilateration of a plurality of ranging values.

摘要： Determination of a signal loss profile relative to a receiver based on measured signal power of a sounding signal from a sounding transmitter having a known signal power in free space relative to the receiver. The signal loss profile may include a plurality of signal loss values corresponding to a plurality of received sounding signals at the receiver. In an embodiment, the sounding signal may comprise a GNSS navigational signal (e.g., a GPS signal). The signal loss profile may be used to extrapolate signal loss for a transmitter collocated with the receiver. In turn, the signal loss profile may be used in conjunction with a shared spectrum system to model a signal propagation from the collocated transmitter when determining allocation of a shared spectrum resource of the shared spectrum system.

摘要： A method and system for precise position determination of general Internet Protocol (IP) network-connected devices. A method enables use of remote intelligence located at strategic network points to distribute relevant assistance data to IP devices with embedded receivers. Assistance is tailored to provide physical timing, frequency and real time signal status data using general broad band communication protocols. Relevant assistance data enables several complementary forms of signal processing gain critical to acquire and measure weakened or distorted in-building Global Navigation Satellite Services (GNSS) signals and to ultimately extract corresponding pseudo-range time components. A method to assemble sets of GNSS measurements that are observed over long periods of time while using standard satellite navigation methods, and once compiled, convert using standard methods each pseudo-range into usable path distances used to calculate a precise geographic position to a known degree of accuracy.

摘要： A GNSS cooperative receiver system that can be utilized when one or more GNSS receivers is in a compromised position where it cannot receive direct signals from a sufficient number of GNSS satellites. This may in the interior of an office building or multi-dwelling unit, which may be in the vicinity of other tall buildings. The receivers determine their relative positions from one of various ranging techniques, and then with this relative position information, pseudoranges, and correlation values from the various GNSS receivers, the best GNSS solution can be determined for the group of cooperative receivers. This could include two or more receivers in a group. There also related techniques for one receiver to be a designated, remote anchor for other GNSS receivers that need such assistance.
