Such an architecture is designed for customizing a navigation system by combining, adding, replacing or removing one or more removable RF section modules. At least one of the RF section modules has a mutually complementary frequency set with respect to a frequency set of one or more of the other RF section modules in the system. | 06-10-2010 |
20100156710 | SYNCHRONIZATION INDICATION IN NETWORKS - Systems and methods provide a network's synchronization status to a terminal when the terminal receives a transmission from the network. This network synchronization status can be indicated in accordance with various methods including, but not limited to the following: with a status flag in a network message; in a network capability indication; in a network's positioning capability indication; cell/network time relation information; in a time relation information of different Radio Access Technologies; and implicitly with another parameter and/or by a request for a certain measurement. When the network's synchronization status is determined, accurate time information/time assistance data can be maintained at the terminal. | 06-24-2010 |
20100176989 | PSEUDO-SATELLITE TRANSMITTER AND METHOD OF TRANSMITTING GPS SIGNALS USING PSEUDO-SATELLITE TRANSMITTER - A pseudo-satellite transmitter includes a GPS unit, a transmission power control unit, and a plurality of antennas. The GPS unit generates a GPS signal of a pseudo-satellite. The transmission power control unit generates a plurality of GPS signals having different power levels based on the GPS signal generated by the GPS unit and a distance from a shadow area to the pseudo-satellite transmitter. Each antenna is configured to wirelessly transmit the GPS signals with different power levels output from the transmission power control unit to a corresponding one of a plurality of shadow areas according to the distance from the shadow area to the corresponding antenna. | 07-15-2010 |
20100201568 | METHOD FOR IMPLEMENTING GPS SURVEYING FIELD WORK PLANNING USING 3D TOPOGRAPHIC INFORMAITON AND METHOD FOR ANALYZING 3D TOPOGRAPHIC INFORMATION - A method for implementing GPS surveying field work planning by using three dimensional topographic information is provided, comprising the steps of: obtaining three dimensional topographic information according to the location of a GPS receiver; obtaining maximum topographic elevation angle information from the GPS receiver to the terrain for each azimuth using the three dimension topographic information; obtaining elevation angle of satellites from the GPS receiver according to the satellite ephemeris or almanac; determining whether observation is usable according to the maximum topographic elevation angle information along the satellite bearings, and the elevation angle of satellites; and estimating the positioning accuracy according to the usable satellite observations. | 08-12-2010 |
20100214163 | TRANSMITTING LOCATION INFORMATION OF A BEACON - According to one embodiment of the present invention, determining the location of a target of interest includes determining a beacon location of the beacon. The beacon location is transmitted to a sensor. The sensor is operable to determine a sensor location of the sensor. The sensor is further operable to determine a target location of the target according to the beacon location and the sensor location. The target location is distinct from the beacon location. | 08-26-2010 |
