摘要： A moving coil measuring instrument wherein at least one end of the axis (3) of rotation of the moving coil (1) is supported so as to permit adjustment of that end of the axis (3) in a direction substantially perpendicular to the axis (3), such adjustment correcting for non-ideal operation of the instrument. The adjustment is effected by rotation of a support member (5, 7), defining the one end, rotatably mounted in a frame member (9) of the instrument, the support member (5, 7) defining the one end at a location displaced from the axis (31, 32) of rotation of the support member (5, 7).

摘要： Positioning systems and methods comprise a network of transmitters that broadcast positioning signals comprising ranging signals and positioning system information. A ranging signal comprises information used to measure a distance to a transmitter broadcasting the ranging signal. A reference sensor array comprising at least one reference sensor unit is positioned at a known location. A remote receiver includes an atmospheric sensor collecting atmospheric data at a position of the remote receiver. A positioning application is coupled to the remote receiver and generates a reference pressure estimate at the position of the remote receiver using the atmospheric and reference data from the reference sensor array. The positioning application computes the position of the remote receiver using the reference pressure estimate and information derived from at least one of the positioning signals and satellite signals that are signals of a satellite-based positioning system. The position includes an elevation.
