Ambiguity Dilution of Precision:
Integer carrier phase ambiguity resolution is often a prerequisite for high precision GPS positioning. It applies to a great variety of GPS models, including those which are used in hydrographic applications and marine positioning. Since the quality of kinematic GPS positioning depends critically on whether the correct integer ambiguities are used or not, it is of importance to have easy-to-com...
متن کاملDilution of Precision
There is some uncertainty, however, in the receiver’s measurements, and so the location of the range circles will be inexact and result in an error in the computed position. This error depends on the geometry relating the receiver and the transmitters. In Figure 1a, the transmitters are far apart, giving a relatively small region in which the receiver must lie with some degree of certainty. Tra...
متن کاملNoise Characteristics in High Precision GPS Positioning
In this contribution we present the results of three different studies in which the method of least-squares variance component estimation (LS-VCE) was used to infer the stochastic properties of GPS data. The three studies cover the GPS geometry-free model, the GPS coordinate time series model, and the GPS zero-baseline model. In the GPS geometry-free model, LS-VCE is applied to assess the preci...
متن کاملdevelopment of different optical methods for determination of glucose using cadmium telluride quantum dots and silver nanoparticles
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
Trend of Precision Positioning Technology
This paper describes recent precision positioning technology. First, recent precision positioning mechanisms are introduced. Although ball screw mechanisms are widely used in industrial machines, the use of linear motors and the development of planar motors recently increase. Several linear motor mechanisms show the acceleration higher than 10G. The linear motor mechanism developed in my group ...
