Advanced navigation satellite system positioning method and system using delayed precise information
Patent number: 10670734Abstract: The invention relates to a method carried out by a navigation satellite system (NSS) receiver or a processing entity receiving data therefrom, for estimating parameters useful to determine a position. The NSS receiver observes NSS signals from NSS satellites over multiple epochs. A first filter, called “timely estimator”, and second filter, called “precise estimator” and delayed with respect to the timely estimator, are operated. The estimators use state variables, and make use of NSS signals observed by the NSS receiver or information derived therefrom. The precise estimator further computes its state variable values based on observations that are not derived from NSS signals observed by the NSS receiver. The values of some of the state variables computed by the timely estimator are recurrently replaced by values from the precise estimator. A corresponding system is also disclosed.Type: GrantFiled: August 29, 2017Date of Patent: June 2, 2020Assignee: Trimble Inc.Inventors: Markus Glocker, Nicholas Charles Talbot, Bruno Scherzinger -

Patent number: 8416130Abstract: A method and system obtains precise survey-grade position data of target points in zones where precise GPS data cannot be obtained, due to natural or man-made objects such as foliage and buildings. The system comprises position measurement components such as a GPS receiver, together with an inertial measurement unit (IMU) and an electronic distance meter (EDM) or an image capture device all mounted on a survey pole. The system and method obtains GPS data when outside the zone and uses the other position measurement systems, such as the IMU, inside the zone to traverse to a target point. The EDM or the image capture device may be used within or without the zone to obtain data to reduce accumulated position errors.Type: GrantFiled: May 31, 2011Date of Patent: April 9, 2013Assignee: Trimble Navigation LimitedInventor: Bruno Scherzinger

Patent number: 7149629Abstract: A Land Surveyor System with Reprocessing is carried by a surveyor moving from a first known position at the start of a survey interval to a second known position at the end of the survey interval has an AINS (aided inertial navigation system) that provides a continuing sequence of time-indexed present position values. A Position Computing System uses a program that stores the sequence of time-indexed present position values in a memory. A reprocessing computer and program is activated at the second known position to access and process the continuing sequence of time-indexed present position values with a smoothing program to provide indexed and adjusted present position values for at least some of the time-indexed present position values. The system is packaged for transport and use by a surveyor. A switch permits the surveyor to signal that the unit is stationary as a reset for the AINS.Type: GrantFiled: October 5, 2004Date of Patent: December 12, 2006Assignee: Applanix Corporation, Inc.Inventors: Bruno Scherzinger, Blake Reid, Erik Lithopoulos

Patent number: 7043364Abstract: A walking stick navigator (WSN) apparatus and process comprises an aided INS (AINS) on a staff assembly similar in operation and appearance to a GPS survey instrument. However, when GPS is available, the AINS is aided by GPS data, and the surveyor manipulates the staff assembly like a standard GPS survey instrument. When GPS is not available due to signal obstruction, the surveyor manipulates the staff assembly as a walking stick. A switch means coupled to the lower end of the staff assembly provides a stationary interval signal when the surveyor plants and holds the WSN on the ground while walking. An input process is coupled to the AINS output signals and to the stationary interval signals and provides at least one aiding input signal to the AINS for each successive stationary interval, thereby allowing the AINS to control its velocity error and position drift during a GPS outage.Type: GrantFiled: January 25, 2005Date of Patent: May 9, 2006Assignee: Applanix Corporation, Inc.Inventor: Bruno Scherzinger

Patent number: 6853909Abstract: A walking stick navigator (WSN) apparatus and method comprises an aided INS (AINS) on a staff assembly with the “look and feel” of a GPS survey instrument. When GPS is available, the AINS is aided by GPS data, and the survey or manipulates the staff assembly like a standard GPS survey instrument. When GPS is not available due to signal obstruction, the surveyor manipulates the staff assembly as a walking stick. A switch means coupled to the lower end of the staff assembly provides a stationary interval signal when the surveyor plants and holds the WSN on the ground while walking. A digital computer is coupled to be responsive to AINS output signals and to the stationary interval signals and to run a program that solves a position aiding algorithm and a velocity aiding algorithm that provide at least one aiding input to the AINS for each successive stationary interval.Type: GrantFiled: November 29, 2002Date of Patent: February 8, 2005Assignee: Applanix Corporation, INCInventor: Bruno Scherzinger
