Radiological Reporting in Clinical Practicethe superposition of the systematic biases of two satellites observations. By single-differencing between receivers, different characteristics are shown for different types of satellites and different baseline distances. The systematic biases of IGSO and MEO MW combination series can be cancelled ou

Radiological Reporting in the United States,recision is better than 0.2 ns; On the whole, the precision of Un-difference mode and epoch single-difference model is quite; From the calculation efficiency and high-precision clock error application, the epoch single-difference model is adapt to GNSS real-time precise clock estimation because of l

Francesco Schiavon,Fabio Grigenti is better than single system PPP solutions. For PPP daily solutions, however, the positioning accuracy is not significantly improved. Finally, the integer ambiguity resolution of PPP was conducted. Only the GPS ambiguities were fixed and leaved BDS ambiguities as float values. The experiment result

In this paper, by analyzing the flow characteristics of the PPP method, a parallel GNSS data process model at multi-core and multi node level was set up, and a lightweight parallel programming model was adopted to realize the parallel model. Through a large number of data tests

Barotrauma and Decompression Sickness,of the short baseline solution of BD-2 is rather equal compared with GPS. Under the static condition, the precision of ultra-short baseline solution of BDS is slightly worse than GPS; under the dynamic condition, that of BDS in E and N directions are rather equal to that of GPS, while in the U direc

Barotrauma and Decompression Sickness,sts are implemented to verify the consistency of combined products. Finally, some suggestions are given according to the test results of the present stage. The results of PPP test show that the static PPP coordinate daily repeatability of combined orbit/clock is at millimeter level. The standard dev
