    摘要: An optimum measurement subset with a specified number n of elements is generated from a set of N>n weighted input global navigation satellite system (GNSS) measurements. A group of trial measurement subsets is generated by removing a different individual weighted input GNSS measurement from the set. A value of accuracy criterion for a target parameter is calculated for each trial measurement subset, and the trial measurement subset with the minimum value of accuracy criterion is selected. A new group of trial measurement subsets is generated by removing a different individual weighted GNSS measurement from the previously selected trial measurement subset. A value of accuracy criterion is calculated for each new trial measurement subset, and a new trial measurement subset with the new minimum value of accuracy criterion is selected. The process is repeated until the selected trial measurement subset has the specified number n of elements.

    摘要: An optimum measurement subset with a specified number of elements is generated from a set of input global navigation satellite system (GNSS) measurements. A design matrix and a weight matrix are generated. Values of a set of coefficients corresponding to the set of input GNSS measurements are calculated. The value of a specific coefficient is calculated as the ratio of the change in value of the at least one target parameter resulting from the change in value of the specific input GNSS measurement to the change in value of the sum of squared residuals resulting from the change in value of the specific input GNSS measurement. The optimum measurement subset is selected based at least in part on the values of the set of coefficients.

    摘要: A putting stroke apparatus and method is provided that determines and simulates the proper putting stroke using at least an aiming direction and initial ball speed for successfully making a particular putt based on particular putting green characteristics and the location of the golf hole on the putting green. A pendulum putter apparatus is coupled with a putting diagnostic tool wherein the putting diagnostic tool determines at least an aiming direction and initial ball speed for a particular putt using inputs such as: (i) topographic information (e.g., contours) specific to the green; (ii) the green speed at a particular time; (iii) the golf hole location (i.e., the physical location of the golf hole); and (iv) the golf ball location on the green (i.e., the physical location of the golf ball).
