Research on Piecewise Linear Fitting Method Based on Least Square Method in 3D Space Points
Because the known data cannot be completely found to determine the function of the corresponding relationship, it is needed to describe the data in tabular form. As the research goes on, people want to use some simple mathematical functions to express the relationship between the data and the data. In the process of data processing, the least square method is one of the most common methods. Bas...
متن کاملProgress in Carrier Phase Time Transfer
The progress of the joint Pilot Project for time transfer, formed by the International GPS Service (IGS) and the Bureau International des Poids et Mesures (BIPM), was recently reviewed. Three notable milestones were set. 1) The IGS will implement, at least in a test mode, an internally realized time scale based on an integration of combined frequency standards within the IGS network. This will ...
متن کاملA Study of GPS Carrier-Phase Time Transfer Noise Based on NIST GPS Receivers
To do a better time comparison between high-precision clocks (such as a Cesium-fountain clock and Hydrogen-maser clock), we want to study and eventually lower the GPS carrier-phase time transfer noise. The GPS carrier-phase time transfer noise comes from four sources: GPS satellite, GPS signal path, ground receiving equipment (receiver and antenna), and data-processing algorithm. This paper foc...
متن کاملA Gradient-Descent Method for Curve Fitting on Riemannian Manifolds
Given data points p0, . . . , pN on a closed submanifold M of R n and time instants 0 = t0 < t1 < . . . < tN = 1, we consider the problem of finding a curve γ on M that best approximates the data points at the given instants while being as “regular” as possible. Specifically, γ is expressed as the curve that minimizes the weighted sum of a sum-of-squares term penalizing the lack of fitting to t...
