    摘要： An in-vehicle antenna device includes: a dielectric element having a front surface, first and second side surfaces and a rear surface and including a power supply point on both the first and second side surfaces, a first conductive surface on the first side surface, a second conductive surface on the second side surface, and a third conductive surface on the rear surface; and an antenna element including a base element coupled with the power supply point at one corner of the front surface and a branch element connected to the base element and having an end. A part of the branch element moves apart from one of the first and second conductive surfaces as it goes from the base element to the one end of the branch element. The front surface is attached to a windshield of a vehicle.

    摘要： An antenna system for use in a wide frequency band has a reflection board that has a board shape with an outer edge and an inner edge. The antenna system connects the reflection board and an antenna module in a manner that does not allow a flow of a direct current. Further, a dimension of the reflection board along a polarization direction of the antenna module has a value that is equal to or greater than a product of a maximum wavelength of a usable frequency band multiplied by a wavelength reduction rate of a dielectric material.

    摘要： A mobile station requests a start of positioning and receives a response of positioning from a positioning server, following which it informs the positioning server of its own station information and neighboring base station information gathered through searching the neighboring base stations. Thereby, the mobile station receives assistant information regarding GPS satellites to be captured based on a station location designated by the positioning server and then it measures a GPS signal and a base station signal such as an apparent signal delay. In the case that the positioning information collected as described above is sufficient for location computing, it displays the location computed by the positioning server. In contrast, in the case that the positioning information is insufficient, it displays “positioning impossible” without sending the positioning information to the positioning server.

    摘要： A radio communication terminal is used in a position specifying system, in which both retrieval timing and retrieval time of each of GPS satellites are received via a communication base station from a position information server. The position information server specifies a position of the radio communication terminal based upon at least GPS satellite information received from the radio communication terminal. The radio communication terminal corrects at least any one of both retrieval timing and retrieval time so that the retrieval timing is moved, or the retrieval time is prolonged. The radio communication terminal retrieves the GPS satellites based upon the corrected retrieval timing and the corrected retrieval time.

    摘要： An on-board communication equipment on each of two vehicles receives a radio wave from two or more GPS satellites, and determines a carrier wave phase of the received radio wave. Then, the on-board communication equipment on one vehicle receives, from the other vehicle, information on the carrier wave phase observed in the other vehicle. Further, the on-board communication equipment calculates a relative position of a self vehicle relative to the other vehicle by a Carrier-Phase DGPS positioning based on a difference between two carrier wave phases (e.g., single difference, double difference or the like), that is, one from the self vehicle and one from the other vehicle, both having the same observation time, from among the available carrier wave phases.
