Patent number: 8810452Abstract: Transmitters are located with a network of sensors by measuring signal characteristics at multiple known locations and processing these measurements at a central node. The sensors communicate their location to the central node along with measured characteristics of the transmitter's signal, and may be required to synchronize with other sensors. Often, GNSS receivers are utilized to locate and synchronize the sensors. However, the GNSS signals may be attenuated by obstructions. In this case, the sensors determine their location by making ranging measurements with sensors that can receive the GNSS signals. The waveform for the wireless backhaul permits this ranging. Additionally, many sensors can determine their location and time synchronize with the geolocation network through reception of signals from other sensors even if they do not have a direct connection to sensors that know their location and are time synchronized.Type: GrantFiled: May 24, 2010Date of Patent: August 19, 2014Assignee: TruePosition, Inc.Inventor: Jeffrey F.

Patent number: 8478291Abstract: A large volume of high accuracy location data is determined in many commercial wireless networks from location based services (LBS) and, in the United States, for E911. Uplink-Time-Difference-of-Arrival (UTDOA) and Assisted GPS (AGPS) are the predominant geolocation technologies providing these high accuracy locations. In the US alone over 10 million wireless subscribers are located every month because they dial the national emergency number “911” on their mobile phones. This rich set of location data provides an a priori distribution of the location of subscribers in the wireless network. All digital wireless communications networks have a mechanism for the subscribers to time synchronize their handsets to the network. This mechanism provides a band of ranges from the serving cell site to the handset. An a posteriori location estimate can be determined very quickly by considering the a priori distribution of callers in the range band that the current subscriber is in.Type: GrantFiled: August 27, 2010Date of Patent: July 2, 2013Assignee: TruePosition, Inc.Inventors: Jeffrey F.

Patent number: 8463297Abstract: A method for use in controlling a mobile device's access to one or more wireless communications networks (WCNs) with an overlaid wireless location system (WLS) includes monitoring a set of one or more predefined signaling links of at least one WCN, and detecting an event associated with the mobile device. Next, using a low-accuracy location function of the WLS, the system determines that the mobile device is within a defined area of interest and is potentially within a defined quiet zone. Next, using a high-accuracy location function of the WLS, the system determines a precise geographic location of the mobile device and based thereon confirms that the mobile device is within the quiet zone or at least within an area of ambiguity around the quiet zone. Finally, the mobile device's access to the wireless communications network is limited, e.g., according to a pre-defined rule established by the carrier.Type: GrantFiled: December 27, 2007Date of Patent: June 11, 2013Assignee: TruePosition, Inc.Inventors: Jeffrey F.

Patent number: 8436768Abstract: A Wide Area Sensor Network is disclosed that utilizes wideband software defined radios (SDRs) to provide a capability to monitor the airwaves over a wide frequency range, detect when critical frequencies are being jammed or otherwise interfered with, and locate the source of the interference so that the interference can be eliminated. In addition, a diversity receiver is disclosed. The diversity receiver generates position, time and frequency references for use in locating and synchronizing sensor platforms of a WLS. In an illustrative embodiment, the diversity receiver comprises a first receiver subsystem comprising a terrestrial broadcast receiver, and a common processor platform (CPP) coupled via first link means to the first receiver subsystem. The first receiver subsystem provides a stable time reference and position information to the CPP via the first link means.Type: GrantFiled: July 24, 2009Date of Patent: May 7, 2013Assignee: TruePosition, Inc.Inventors: Jeffrey F. Bull, Benjamin H. Cohen, Adam W. Norgaard

Patent number: 8331955Abstract: A wireless location system is configured to operate in a CDMA-based wireless communication network. In exemplary embodiments, location measuring units (LMUs) can synchronize to sectors of base stations and store sector timing information. In response to a request to geo-locate a mobile device communicating with a sector, sector timing information for the servicing sector is sent to other LMUs and the LMUs can use the sector timing information to detect uplink signals transmitted by the mobile device. The location of the mobile device can then be estimated based on time of arrival measurements made by the LMUs.Type: GrantFiled: December 28, 2010Date of Patent: December 11, 2012Assignee: TruePosition, Inc.Inventors: Jeffrey F. Bull, Robert J. Anderson

Patent number: 8213957Abstract: A Network Autonomous Wireless Location System (NAWLS) is designed to allow for precise location of a mobile device (e.g., a cell phone) without interconnection to, and with minimal disruption of, the local wireless communications network. Using distributed radio network monitors (RNM) and a managed network emulator (NE); mobile devices are sampled, acquired or captured. Once triggered by the RNM or NE, an untethered wireless location system (U-WLS) is used to calculate a precise location. The U-WLS; comprising mobile receiver sites, each capable of self location, exchanging information with other components of the NAWLS, and receiving or exchanging signals from the mobile device; utilizes various network-based and handset-based wireless location techniques dependent on the deployed options. In addition, the NAWLS includes data links interconnecting the U-WLS, NE and RNM.Type: GrantFiled: April 22, 2009Date of Patent: July 3, 2012Assignee: TruePosition, Inc.Inventors: Jeffrey F.
