20100225535 | TARGET OBJECT POSITION EVALUATION DEVICED USED IN SPORT EVENTS - A target object position evaluation device of the present invention that is used at sport events includes a central processing unit (CPU), a global positioning system (GPS) module, an environment detection unit, a memory and a display device. In addition to the positioning function, the target object position evaluation device further uses the environment detection unit to collect various kinds of environmental information and estimate the mechanics of a motion trajectory in the CPU to provide better shooting information to a user, so that the user can easily obtain the shooting information such as the striking or shooting information required in an exercising process. In addition to the fitness effect, the user also can achieve a better result and gain more fun from the exercising process. | 09-09-2010 |
20100245171 | METHOD AND APPARATUS FOR PRECISE RELATIVE POSITIONING IN MULTIPLE VEHICLES - A system and method for determining the position and velocity of a plurality of vehicles relative to a host vehicle using GPS data. The method includes building a graph of the vehicles that define weighted baselines between each of the vehicles and the host vehicle and each of the vehicles where the weighted baselines define a geometric dilution of precision between the vehicles. The method then determines the optimal baseline between the host vehicle and each of the other vehicles using the weighted baselines based on the lowest geometric dilution of precision. The method then computes the relative position and velocity between all of the vehicles and the host vehicle using the optimal baselines. | 09-30-2010 |
20110032145 | Method and System for Performing Gesture-Based Directed Search - A method and apparatus for performing gesture-based directed search using a portable electronic device is provided. The method includes receiving geographic location information of the portable electronic device. At least one signal associated with a motion of the portable electronic device is detected and directional information is determined based on the at least one detected signal and relative to the geographic location information of the portable electronic device. Further, the method includes performing a search for at least one point of interest based on the directional information and the geographic location information of the portable electronic device and rendering the at least one point of interest at the portable electronic device. | 02-10-2011 |
20130069823 | Method and Apparatus for Generating and Using a Regional-Terrain Model - A method and apparatus for computing position using a regional-terrain model is provided. The method includes obtaining from at least three satellites pseudorange measurements, computing a transitional position by using a default altitude with a large uncertainty, using this transitional position to obtain from a terrain model altitude information associated with a region, and computing an accurate three-dimensional position as a function of the pseudorange measurements and the altitude information. The region defines a boundary, and the boundary includes the transitional position. | 03-21-2013 |
20140062775 | GPS MAPPING SYSTEM AND METHOD FOR USE BY HUNTERS, CAMPERS AND OUTDOOR ENTHUSIASTS - A tracking and mapping system for outdoor use includes a first GPS locator located either at a base station or on a hunting accessory such as an arrow. The system also includes a second GPS locator for identifying a user's location, and an electronic display unit for communicating with a global positioning satellite and displaying a map showing icons representing locations of the first and second GPS locators. The second OPS locator may be embedded in the electronic display unit, which may be a mobile wireless handheld device, a tablet or other portable computer having wireless connectivity. The electronic display unit maps the present location of each of the GPS locators in relation to a direction such as north, south, east or west. Optionally, separate GPS locators may be placed at a base station and in an arrow. A method of using the tracking and mapping system is also described. | 03-06-2014 |
20140168009 | Multi-IMU INS for vehicle control - Multi-IMU INS for vehicle control allows GNSS-derived position and velocity to be measured at an antenna and applied to the estimation of position, velocity and attitude at a separate control point even when the spatial relationship between antenna and control point is not constant. | 06-19-2014 |
20140210663 | MEASURING SYSTEM AND METHOD FOR DETERMINING NEW POINTS - A geodetic measuring system having at least one reference component which defines a reference point, wherein an absolute position of the reference point is known, and at least one new-point determination component which derives a relative new-point position. It is also possible to derive mutual relative reference information between the reference component and the new-point determination component, in particular for the purpose of referencing with respect to the reference-point position. The measuring system also has an automotive, unmanned, controllable air vehicle, wherein the air vehicle has the reference component which provides the at least one reference point as a mobile reference point. The air vehicle is also designed in such a manner that the reference component can be spatially freely displaced by the air vehicle, in particular can be positioned in a substantially fixed position. | 07-31-2014 |
20150369924 | METHOD AND SYSTEM FOR HIGH-ACCURACY DIFFERENTIAL TRACKING OF GLOBAL POSITIONING SYSTEM (GPS) RECEIVERS - Aspects of the present invention relate to methods and systems for high-accuracy differential tracking of global positioning system (GPS) receivers. In one embodiment, a network having multiple receivers is provided. The receivers are configured to communicate with each other. The receivers in the network are configured to measure raw satellite data, and to share the raw satellite data measured by each receiver. Each receiver is configured to process the measured raw satellite data with a Peak Ambiguity Function Value (AFV) Tracking Solution (PATS) to track relative motions of the neighboring receivers so as to derive relative location information for the plurality of receivers. | 12-24-2015 |

20160377736 | SATELLITE NAVIGATION RECEIVER FOR RELATIVE POSITIONING WITH BIAS ESTIMATION - A tracking module processes the determined correlations to track a carrier of the received composite signal for estimation of a change in phase over a time period between a receiver antenna and one or more satellite transmitters that transmit the received signal as the receiver changes position with respect to an initial position during the time period. A relative position estimator estimates the relative position of the navigation receiver with respect to an initial position over the time period time by time-differencing of the phase measurements of the one or more tracked carrier signals. Bias estimators can estimate or compensate for errors in initial position and temporal changes in receiver clock and tropospheric delay. | 12-29-2016 |
