Abstract: A base station apparatus includes a processor, a memory and a communication circuit. The processor is configured to set a waiting period in which a packet from a terminal device to which a connection has not been established is awaited. The memory is configured to store data that is processed by a terminal device to which a connection is established. The communication circuit is configured to, upon receiving a first packet from a communication terminal device in the waiting period, transmit to the communication terminal device a second packet containing the data and information used by the communication terminal device for establishing a connection.

Abstract: In a laser receiver receiving a laser beam from a laser transmitter and a laser receiving system composed of a plurality of laser receivers, a plurality of photo devices are arranged on an acceptance surface so that acceptance angles of the laser beam thereof are mutually different in order to detect distances between an acceptance position of a center point of a received laser beam on an acceptance surface and a reference point and an elevation angle of the received laser beam from a reference surface. Also, distance detection means respectively compare acceptance levels of the photo devices detected by the level detection means with thresholds, thereby detecting distance between the center point of the laser beam and the reference point of the acceptance surface by combination of comparison results thereof.

Abstract: A position measuring apparatus is disclosed. The apparatus has a receiver for receiving signals from multiple satellites and measuring the position of a mobile station based on the received signals. In addition, an angle determination unit determines angle range depending on the positional relation between the measured position of the mobile station and an obstacle. An orbit information extraction unit extracts orbit information indicating orbits of the satellites from the received signals. A measurement unit measures the quality of the signals from at least one satellite that is expected to exist within the angle range based on the extracted orbit information. Finally, a correction unit corrects the position of the mobile station to another position having a different height, according to the measured quality of the signal from the within-angle range satellite.

Abstract: A reception high-frequency unit receives a GPS signal transmitted from a satellite configuring GPS. A signal generation unit generates a plurality of pseudo random noise codes that are used for the positioning operation by a positioning apparatus for implementing a positioning operation based on the GPS signal and that are in the same form as that of the GPS signal. A transmission high-frequency unit generates and transmits based on the pseudo random noise codes, a positioning signal in the same form as that of the GPS signal. A transmission control unit controls the transmission high-frequency unit in such a way that a time difference based on the GPS signal received by the reception high-frequency unit is assigned to each positioning signal and the thus-assigned positioning signal is transmitted.
