摘要： Tools and techniques for estimating elevations, including without limitation tools and techniques that employ mobile stations with laser detectors for receiving a beam emitted from a laser source and estimating an elevation of the mobile station based on the received beam. In some instances, a mobile station may be configured to identify, based on some or all of a variety of factors, a situation in which the elevation of the detector is likely to change to the extent that the slope of the emitter needs to be adjusted to account for this change in elevation. The mobile station may also be configured to inform the laser source that the slope of the emitted beam should be adjusted. In response, the laser source may adjust the slope of the emitted beam accordingly.

摘要： A laser transmitter projects a beam of laser light outward while raising and lowering the beam. The beam may define a conical surface of varying inclination. The transmitter includes a laser source that directs a beam generally vertically, and a beam diverting element. The beam diverting element is positioned in the path of the beam, intercepting the beam and redirecting it. The beam emerges from the transmitter as a non-vertical beam that is raised and lowered. The diverting element may include a pair of mirrors configured as a pentaprism, with one of the mirrors pivotable. Alternatively, the diverting element may include a plurality of micro mirrors. Also, the diverting element may include a conical reflector and an annular lens which is cyclically raised and lowered. The beam may be raised and lowered cyclically according to a predetermined schedule, or it may be raised and lowered non-cyclically.

摘要： Computer-implemented methods and apparatus are presented for processing data collected by at least two receivers from multiple satellites of multiple GNSS, where at least one GNSS is FDMA. Data sets are obtained which comprise a first data set from a first receiver and a second data set from a second receiver. The first data set comprises a first FDMA data set and the second data set comprises a second FDMA data set. At least one of a code bias and a phase bias may exist between the first FDMA data set and the second FDMA data set. At least one receiver-type bias is determined, to be applied when the data sets are obtained from receivers of different types. The data sets are processed, based on the at least one receiver-type bias, to estimate carrier floating-point ambiguities. Carrier integer ambiguities are determined from the floating-point ambiguities. The scheme enables GLONASS carrier phase ambiguities to be resolved and used in a combined FDMA/CDMA (e.g., GLONASS/GPS) centimeter-level solution. It is applicable to real-time kinematic (RTK) positioning, high-precision post-processing of positions and network RTK positioning.

摘要： Methods for chaining together two or more navigation or survey stations to complete a project, where only adjacent stations in the chain have contact with each other. The location of a mobile reference station is determined and corrected, if necessary, using location determination (LD) signals from an LD system such as GPS, GLONASS, LEO or the like. The location of a first rover station is determined using RTK information and signal differencing from the mobile reference station. The location of a second rover station is determined using RTK information and signal differencing from the first rover station, in a chain of location determinations. Standard electronic distance measuring equipment and techniques can be used to supplement these methods in an integrated approach. Location consistency checks are provided by using RTK analysis to redetermine the location of one or more preceding stations in the chain. The invention can be used to direct a moving vehicle toward a selected structure for landing, tie-up, maintenance, refueling and similar activities.

摘要： A machine control system uses a laser system and global navigation satellite system to determine the position of the machine. The laser system has a laser detector positioned in a known and fixed relationship with the nominal phase center of a global navigation satellite antenna. The laser detector receives laser light transmitted from a laser transmitter. The outputs of the laser system and the global navigation satellite system are used together to determine the position of the transmitter prior to being used to determine the position of the machine.
