20150316651 | TAPERED COHERENT INTEGRATION TIME FOR A RECEIVER OF A POSITIONING SYSTEM - Approaches to signal processing using tapered coherent integration time period durations. In this regard, signal processing of received signals (e.g., received satellite navigation signals) may be received at a receiver. The received signals may be processed in a coherent integration process whereby the duration of subsequent coherent integration time periods are reduced in response to errors resulting from frequency instability that grows in time. As such, relatively long durations for coherent integration times may result in improved signal to noise ratios (SNRs) for integrated signals in initial coherent integration time periods. However, as errors that are introduced into the signal processing due grow over time, the durations of subsequent coherent integration time periods may be reduced, thus reducing the effect of the error in a SNR of resulting integrated signals. In turn, receiver sensitivity may be improved. | 11-05-2015 |
20140370912 | INDOOR LOCATION USING A PACKET SYNCHRONIZED RECEIVER ARRAY - 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. | 12-18-2014 |
20130135147 | SYSTEMS AND METHODS FOR IP AND VOIP DEVICE LOCATION DETERMINATION - 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 broadband 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. | 05-30-2013 |
