| A method of and system for calibrating un-calibrated time information within a mobile terminal 101 is disclosed. The terminal has a receiver 203 capable of receiving signals from which calibrated time information carried by a calibrated system (a satellite positioning system) can be extracted, and a receiver 200 capable of receiving signals from which un-calibrated time information carried by an un-calibrated stable system (a cellular communications system) may be extracted. The time offset between calibrated time information extracted from the calibrated system and un-calibrated time information extracted from the un-calibrated stable system is determined at a first terminal position where the signals from the un-calibrated stable system are available, the travel times of the signals from the un-calibrated stable system are known or determined, and the signals from the calibrated system are available. The un-calibrated time information extracted from signals of the un-calibrated stable system received at a second terminal position, is calibrated from known or determined travel times of the signals from the un-calibrated stable system at the second terminal position and the time offset which has been determined. | ||||||

| A method and system for accurately determining the location of the mobile device (10) is disclosed. In the mapping phase collected reference positioning data and collected cell data are used to map a covered area estimation and in the actual location determination phase the covered area estimation is calculated from actual environment data received through wireless cellular communication network (11, 12) and possibly but not necessarily from external databases (17, 19). The covered area estimation comprises at least some of the following calculations: (i) estimation of base station location, (ii) estimation of transmission range, (iii) estimation of signal map and (iv) estimation of area type. The actual location of the mobile device (10) is determined from the covered area estimation based on relative comparison between the actual environment data and estimations (i)-(iv) and weight numbers resulted from the comparison. During the both phases a database is stored in the server (14) and updated whenever new environment data is received. | ||||||

| Methods and apparatus enabling a wireless network to generate data that can be used by a receiver (e.g., UE) to resolve the contributions of individual transmitters, such as to determine its location without resort to external devices such as GPS satellites. In one embodiment, the wireless network comprises a single frequency network (SFN), and a unique base station identifier is embedded within the data, and encoded in a manner which allows the UE to calculate path characteristics (such as path latency, and Direction of Arrival) to triangulate its position. In one variant, the data encoding comprises weighting frames of data from different base stations using an orthogonal matrix. Advantageously, the encoding and embedded identifier are also transparent to legacy UE, thereby allowing for implementation with no infrastructure or UE modifications other than software. Network and user apparatus implementing these methodologies, and methods of doing business, are also disclosed. | ||||||

| 167 | SYSTEM AND METHOD FOR DETERMINING THE POSITION OF AN UNDERWATER VEHICLE | US11675167 | 2007-02-15 | US20090216444A1 | 2009-08-27 | Jonathan C. Crowell |
| A system and a method are provided for determining the position of an underwater vehicle while the vehicle is operating underwater. A buoyant float stays on or near the surface of the water and is attached to the vehicle by thin tether that can include insulated wires. The vehicle moves under the water and pulls the float behind it. The float can receive a localization signal, such as a signal indicating its GPS position, and so can determine its position precisely. The position can be transmitted to the underwater vehicle over the wires located in the tether. The underwater vehicle can use sensors and/or calculations to determine the positional offset of the vehicle from the float buoy and generates its true position based on the known position of the float and the positional offset. The float can be constructed with attributes that will allow the float it operate with a greater tether length, and in turn allow the underwater vehicle to operate at greater depths. The float may also generally carry a radio system for high speed communication of signals from the vehicle while the vehicle is submerged. | ||||||

| An electronic device includes a communication component; a location-determining component; a display; and a computing device all housed within a portable, handheld housing or other enclosure. The communications component transmits and receives mobile communications over a wireless communication network or path and provides identification information to the computing device. The location determining component determines locations of the electronic device as it is carried or driven from place to place and provides corresponding location data to the computing device. The computing device links the identification information with the location data to indicate the location of the device when a communication was made or received. The identification information and location data may be linked by adding a geocode or geotag to the identification information or by cross-referencing the information and data in a database. The computing device may also display a representation of the location data alongside a representation of the communication on a cartographic map and then display some of the identification information for the communication when a user scrolls over or otherwise selects either of the representations. | ||||||

| Techniques to efficiently broadcast position location data (PLD) from a base station to a number of terminals. In one aspect, PLD messages are classified into groups, and each group is broadcast in a different manner. For example, a first group of messages for PLD related to the base station is broadcast in an unscheduled format, and a second group of messages for PLD related to GPS satellites is broadcast in a scheduled format. In another aspect, a schedule for the second group describes the specific PLD elements selected for broadcast, their broadcast order, and the specific time intervals of their broadcast. The schedule is valid for a particular scheduled time interval, and the scheduling table is broadcast multiple times during the scheduled time interval to allow the terminals to quickly retrieve the schedule and ascertain what PLD information is being broadcast and where to look for specific PLD elements. | ||||||

| A method and apparatus for determining a reference time associated with a satellite positioning system. In turn, the reference time, in one embodiment, may be used to determine other navigational information. Such navigational information may include, for example, the location/position of a satellite positioning system (SPS) receiver.

According to another embodiment of the invention, an error statistic is used to determine the reference time. According to yet another embodiment of the invention, two records, each representing at least a portion of a satellite message, are compared to determine time. In one implementation, the SPS receiver is mobile and operates in conjunction with a basestation to determine time and/or other navigational information according to one or a combination of the methods described. | ||||||
