[Books] The GNSS integer ambiguities :estimation and validation DL : 0: The principle of positioning with the Global Positioning System (GPS) is based on determining the distance of at least four GPS satellites to a receiver. For that purpose the so-called code measurements can be used, so that the position of the receiver can be determined up to several meters. In order to allow for navigation with centimeter accuracy, it is however required to use the very precise carrier phase measurements, since the phase of the carrier wave of the GPS signal can be measured up to several millimeters. Unfortunately, a receiver can only measure the phase of the carrier 芒猬

[Software Engineering] mcl DL : 0: 详细介绍MCL算法，是由Sebastian Thrun a, Dieter Fox, Wolfram Burgard, Frank Dellaert所著的论文，发表于Artificial Intelligence上。-Mobile robot localization is the problem of determining a robot’s pose from sensor data. This article presents a family of probabilistic localization algorithms known as Monte Carlo Localization [MCL]. MCL algorithms represent a robot’s belief by a set of weighted hypotheses [samples], which approximate the posterior under a common Bayesian formulation of the localization problem. Building on the basic MCL algorithm, this article develops a more robust algorithm called Mixture- MCL, which integrates two complimentary ways of generating samples in the estimation. To apply this algorithm to mobile robots equipped with range finders, a kernel density tree is learned that permits fast sampling. Systematic empirical results illustrate the robustness and computational efficiency of the approach.  2001 Published by Elsevier Science B.V. Keywords: Mobile robots Localization Position estimation Particle filters Kernel density trees

[Other] UNSCENTED_KALMAN_FILTER_FOR_LOCATION_IN_NON_LINE_O DL : 0: The main reason for inaccuracies observed in location estimation, imposed by the propagation conditions of the wireless channel, is the Non Line Of Sight (NLOS) due to transmitted signal blocking. Because of the NLOS, the first TOA, which bears information related to the mobile terminal position, suffers stronger attenuation than later arrivals and therefore wrong timing information is obtained yielding biased position estimation. Several NLOS mitigation algorithms have been presented. One of the most common approaches consists of correcting the TOA measurements exploiting the fact that the variance of the TOA measurements is significantly increased in NLOS scenarios

[Other] radiocover DL : 0: 这个程序可以计算给定点处的小区信号范围覆盖。-is program computes a map of visibility from a selected point on a topography. It has been written to help the search for radio relay best location. Because it considers only direct line of sight, it gives a good estimation for possible radio link for short distances only (less than 10 km), neglecting curvature of the Earth, Fresnel zone and atmospheric refraction on radio waves propagation. The program computes the relative elevation angle of the mask for each point (the angle is null or negative if the point is visible). The function needs a digital elevation model Z and associated (X,Y) vectors or matrices of coordinates (same unit as Z), position of the point (X0,Y0), the antenna height H0 (for instance 4 m), and the hypothetic antenna height Ha on each topography points (for instance 3 m). When no output argument is given, the function plots a map of the results (color map of mask angles, and blank for visible points, see example screenshot). The script is not fully optimize
