    Abstract: A computer-implemented method for generating at least one segment of an offset path for a vehicle based on at least one segment of a base path is provided. The at least one segment of the base path is represented by a stored set of data points. The computer-implemented method includes comparing the at least one segment of the base path to a curvature constraint to determine if the at least one segment of the base path violates the curvature constraint. The curvature constraint is based on a characteristic of the vehicle and a desired offset distance from the at least one segment of the base path. The characteristic reflects the vehicle's ability to traverse at least one segment of a path. The method further includes modifying the at least one segment of the base path to satisfy the curvature constraint, if the at least one segment of the base path violates the curvature constraint. At least one segment of an offset path for the vehicle to follow is generated based upon the desired offset distance from the modified at least one segment of the base path.

    Abstract: The position of a global navigation satellite system (GNSS) surveying receiver is determined based on a plurality of RTK engines. A first RTK engine is implementing using a first set of parameters. A second RTK engine is implemented using a second set of parameter different than the first set. A plurality of GNSS signals are received from multiple satellites. At least one correction signal is received from at least one base receiver. A first position is determined from the first RTK engine based on the GNSS signals and the at least one correction signal. A second position is determined from the first RTK engine based on the GNSS signals and the at least one correction signal. A final position of the GNSS surveying receiver is determined based on the first position or the second position or a combination of both positions.

    Abstract: The measurements of two GPS and/or GLONASS receivers are related to a common time moment by extrapolating measurement data that has arrived through a connection link with a delay. This common time moment is defined by the user. Cycle slips in the phase-lock loops (PLLs) of the receivers, which may be caused by blockage of direct signals from the satellites, strong interference signals, and reflections, are deflected and corrected in a multi-loop nonlinear tracking system. The procedure of resolution of phase measurement ambiguities comprises the preliminary estimation of floating ambiguities by a recurrent (e.g., iterative) procedure including the simultaneous processing of code and phase measurements for all satellites for each processing time interval, and the gradual improvement of the result as the information is accumulated. After the resolution of ambiguity, the user coordinates are estimated with centimeter accuracy on the basis of phase measurements on the carrier frequency.

    Abstract: A portable geodetic surveying station is disclosed which utilizes a GPS antenna attached to the top portion of a surveyor's stake, or other type monopod. By positioning the bottom portion of the monopod directly upon a desired ground location, and adjusting the angular position of the monopod so that it is precisely vertical, the GPS antenna may be quickly and accurately positioned level and directly above the desired ground location. Additionally, because the monopod has a known, fixed length, the height of the GPS antenna above the desired ground location will always be a constant, and will not vary from one survey point to the next. The GPS antenna and monopod are designed to be used in conjunction with a newly designed geodetic surveying tripod which can be quickly and conveniently set up to support the monopod in its vertical position directly above the desired ground location. The tripod of the present invention includes a tripod head which comprises a base platform, a first housing slidably mounted on the platform to permit the first housing to move along a first directional path, and a second housing slidably mounted within the first housing to permit the second housing to move along a second directional path, generally orthogonal to the first directional path. Mounted pivotally within the second housing is a gimbal which includes a central cavity for receiving the shaft of the monopod. The gimbal allows the angular position of the monopod and GPS antenna to be adjusted independently of the angular position tripod platform.
