Abstract: A two-dimension layout system identifies points and their coordinates, and transfers identified points on a solid surface to other surfaces in a vertical direction. Two leveling laser light transmitters are used with a remote unit to control certain functions. The laser transmitters rotate about the azimuth, and emit vertical (plumb) laser planes. After being set up using benchmark points, the projected lines of the laser planes will intersect on the floor of a jobsite at any point of interest in a virtual floor plan, under control of a user with the remote unit. The laser light planes also project lines that will intersect along the ceiling at a point that is truly plumb above the crossing point on the floor. The laser planes also provide an “implied” plumb line that is projected in space, which is visible along a solid vertical surface between the intersecting floor and ceiling points.

Abstract: The present disclosure relates to a surveying system including a surveying instrument and method for detecting light of fan shaped laser beam. The surveying instrument includes a detector for detecting light of the fan shaped laser beam rotating around a propagation axis with a direction of rotation and having two detector elements arranged in a known spatial relation for outputting a detection signal when irradiated. A position determining unit is used to obtain a first set of detection signals from the detector elements, to determine a first time relation between the detection signals of the first set, and to determine a positional relation between the detector and the propagation axis based on the first time relation.

Abstract: A method of determining the position of a GNSS receiver antenna includes steps of acquiring input data which includes observations at the GNSS receiver antenna of signals of at least clock and position information of GNSS satellites, for each of a plurality of epochs. Float parameters of a state vector from the input data of each epoch are then estimated. The float parameters include receiver antenna position, receiver clock, and at least one ambiguity per satellite. A jump in the at least one ambiguity of at least one satellite from one epoch to another epoch is detected. Then bridge parameters from the input data of at least one epoch and from the estimated float parameters are estimated. The bridge parameters include values sufficient to update the float parameters to compensate for the jump, and the bridge parameters are then used to update the float parameters.

The line is displayed in each of the views in which the line is visible.

The pixels of image data as displayed on the display monitor are identified that are located approximately at edges of the portion of the image. One or more inverse transformations are performed to transform the pixels of image data as displayed on the display monitor to pixels of image data as captured by an image sensor. A portion of image data as captured by the image sensor is identified that corresponds to a portion of the image that surrounds the point. The portion of the image data as captured by the image sensor is displayed on the display monitor without data transformation.

Thereafter, the image data on the display monitor is displayed from a perspective center of the primary image. A stacking order of the plurality of images is arranged so that the primary image is on top.

Abstract: A method and system for controlling power dissipation in a base station of a navigation satellite system (NSS) is disclosed. One method utilizes a sensor to monitor one or more components of the base station. Then, based on information from the sensor, a transmission bit rate is increased from a pre-defined bit rate to an increased transmission bit rate for an NSS message transmitted from the base station without reducing transmission power level of the base station. The method also periodically provides a bit rate update signal at the pre-defined bit rate, the bit rate update signal informing a rover utilizing the base station of the increased transmission bit rate for the NSS message transmitted from the base station.

An operation of the remote device is then controlled from the base station when the speed of the remote device exceeds a speed threshold.

Abstract: Described is a generalized approach for integer parameter estimation, especially in the context of Global Navigation Satellite Systems (GNSS). The problem solved is the case where a definitively correct integer solution cannot be identified for all ambiguity parameters in a reliable way. The proposed solution is to apply a linear transformation to the ambiguities (multiply with a matrix) such that the images of the first and the second candidate (or more) are identical. That way, from the first and second (and possibly more) candidates of the integer least-squares solution, a subset of ambiguity combinations is derived that can be fixed. Thus, it is no longer necessary to choose between the solutions as they coincide for the new ambiguities. The advantage of this approach is maximizing all information still available when finally deriving additional parameters such as position, clock error, atmospheric errors and/or time correlated noise.
