    Abstract: A plurality of antennas may be arranged at positions non-linear to each other. Processing circuitry may set an initial value of one of an attitude angle and an azimuth angle of an azimuth angle calculating device. An integer value bias of a carrier phase difference between at least two groups of antennas may be determined by using the initial value. A base-line vector between the at least two groups of antennas may be calculated by using the integer value bias corresponding to the group of antennas. A multiple base-line verification may be performed, in which validity of the initial value is verified by using each of the base-line vectors calculated using the integer value bias.

  • Patent number: 8194110
    Abstract: In an image recording apparatus using an image recording medium which generates a gas when irradiated with a light beam, the gas and the like are prevented from drifting into a space between the image recording medium and a drum, and thus contamination of the back surface of the image recording medium is prevented. The gas is effectively prevented from drifting to the back surface of a plate P by setting a relative positional relationship of an extending direction of each suction groove L, an attaching position of the plate P, and an air blowing direction so that unclosed regions, not closed by the plate P, of suction grooves L formed in a drum surface do not occur downstream in a gas moving direction.
