Nettet13. jul. 2007 · It is well adapted for post-processed least-square analysis on a single baseline. The method has been extended to more than two stations, giving global clock solutions with integer ambiguity fixing on a station network. In this case, the ambiguities are defined at zero-difference level [ 9, 10 ]. Nettet1. jan. 1993 · Least-Squares Estimation of the Integer GPS Ambiguities Authors: P. J. G.

This distribution is derived for a class of integer ambiguity estimators. Members from this class are the ambiguity estimators that follow from `integer rounding', `integer bootstrapping' and `integer least squares' respectively. sustainable development internships london

This type of least-squares problem was first introduced in [Teunissen, 1993] and has been coined with the term ‘integer least-squares’. Conceptually one can divide the computation of Eq. (2.2) into three different steps. In the first step one simply

NettetAbstract. A probabilistic justification is given for using the integer least-squares (LS) estimator. The class of admissible integer estimators is introduced and classical adjustment theory is extended by proving that the integer LS estimator is best in the sense of maximizing the probability of correct integer estimation.
