Abstract: An antenna adjusting apparatus comprises a sensor that acquires attitude information; a movable axis acquiring unit that acquires a plurality of vectors corresponding to the plurality of axes respectively by acquiring a change in output of the sensor for each of the axes; a first direction acquiring unit that acquires a first direction corresponding to a directional axis of the antenna; a second direction acquiring unit that acquires a second direction, which is a direction with which the directional axis of the antenna is to be aligned; and a calculating unit that calculates, for each of the axes, a correction angle, using the plurality of vectors, wherein the first direction and the second direction are expressed by an Earth-based coordinate system.

Abstract: Ground stations 20, 21 receive any signal transmitted by a geostationary artificial satellite 10, and store the reception signal together with the reception time thereof. A difference ?t in reception time of a same signal between the ground station 20 and the ground station 21 is calculated by performing correlation processing of the reception signal of the ground station 20 and the reception signal of the ground station 21. A distance R20 between the ground station 20 and the geostationary artificial satellite 10 is measured by a distance measurement device. A distance R21 between the ground station 21 and the geostationary artificial satellite 10 is calculated on the basis of the distance R20 obtained by measurement and the difference ?t in reception times, as obtained by correlation processing.

Abstract: A code synchronization circuit for a delay time measurement device used in a low C/N environment is provided. The code synchronization circuit is capable of high precision timing phase measurement and stable operation against variations in the reception level.

Abstract: To display a program guide for making an efficient search for a desired program, there are provided a program guide displaying method and apparatus, and a computer program which controls a computer to carry out the program guide displaying method. The program guide displaying method includes the steps of receiving information on programs to be broadcast on at least one day from a plurality of stations; and placing a plurality of cells in which pieces of the program information are to be displayed, respectively, in a two-dimensional program guide having time and date axes and displaying, in the cells, program information pieces whose airtimes overlap each other on the same airdate, in such a manner that they will not overlap each other.

Abstract: The transmitter of one embodiment of the present invention includes: a S/P section for converting original serial data to parallel data which will correspond to a plurality of subcarriers; and a second IFFT section for converting the parallel data from the frequency domain to the time domain. The transmitter includes, between the S/P section and the second IFFT section, a first IFFT section for modulating the plurality of subcarriers using elements of a matrix derived from an expression for Inverse Discrete Fourier Transform involving time domain signal levels and frequency domain signal levels. The configuration enables CI and PO-CI to be implemented on transmitters and receivers with a simple configuration.

Abstract: A path control packet is sent from a router to a receiver. The receiver capsulates the received packet and transmits a capsulated IP packet to a feed via a ground line. The feed extracts the path control packet by decapsulation and transmits the packet to a router. At the same time, path control information is sent to a satellite line. The router processes the packet as if the path control information from the router reached via the satellite line. When a receiver receives a packet via the satellite line, it transmits the packet as a packet to a router. This router processes the packet as if the path control information from the router reached via the satellite line.
