All computations are undertaken using the Bernese Software System. INTRODUCTION Global Navigation Satellite System (GNSS) observations, such as those utilising the Global Positioning System (GPS), are increasingly used for a wide range of applications, includingGeoscience Australias GNSS Antenna Calibration Facility (ACF). Automated Monitoring of CORSnet-NSW using the Bernese Software Joel HAASDYK, Craig ROBERTS and Volker JANSSEN, Australia 1.
![]() Bernese Gnss Software Professional And ScientificCommercial softwares not only don’t have the complexity of professional and scientific softwares, they have a plain graphical and user friendly environment that it has simplified and quicken dealing with these softwares. In addition, commercial softwares which are produced by those companies that produce GNSS receivers are applied for data processing of general users and engineers. Scientific softwares that mainly are prepared by universities or reliable scientific centers are programmed for utilization in precise and professional tasks. Users now have the option of processing data fromBy increasingly development of GNSS satellite navigation and emergence of new companies for production of related receivers, numerous softwares have been developed for processing of these data that in the most general form, these softwares can be divided into scientific and commercial groups. And more recently even the traditional double-differencing software package such as the BERNESE has been enhanced also to allow precise point positioning. Our theory is that the results and accuracy of scientific softwares is more precise than the results mined from commercial softwares. The reason for using the softwares defaults is that, geomantic engineers presented that they don’t change any default except the zone of region while working with the softwares. In this study, we don’t aim to describe special software, but the goal is to compare softwares with default methods and an algorithm of softwares. Considering the ideas of geomatics engineers, these commercial softwares: CGO, LGO and Ashtech Solutions, are the most used softwares in Iran that we compare this commercial software with a scientific software named Bernese to receive the best answers from comparisons. Nowadays, we are all witness for emergence of many commercial softwares that, it is very crucial to choose the best and the most precise software out of these softwares. Offset Model for Antenna Phase Center of Satellite and ReceiverOffset model of satellite antenna phase and variation of electrical phase of receiver antenna and offset center of receiver’s antenna have many effects on PPP processing. Models of Bernese Scientific SoftwaresIn this part, we will introduce various models of this scientific software and we will explain each of them briefly.2.1. Of course, it should be mentioned that, the present softwares or definable models for each software will be totally different from each other.International Scientific Conference 'Geodynamics and Geospatial Research 2020' UL 77th International Scientific Conference 'Geodynamics and Geospatial Research 2019'2. ![]() These parameters both are presented by IGS processing center weekly and also they are shown in two (A) and (B) Bultons by IERS. Earth rotation parameters are those parameters that are presented in “.eop” standard format. The users can refer to the website of this observatory and fill the related form to receive these models. One of the most famous centers that gives these models is Onsala observatory. These models are presented by solar dynamics observatory, Jet Propulsion Laboratory and NASA. Satellite Ephemeris models are binary files with “.eph” format. These models reveal satellites’ safety at different episodes and Bernese software uses these models for proving the satellites’ safety at observing time and if satellites’ safety is not proved, that satellites’ observation would be deleted from observation list. Super mario odyssey 64 rom downloadThe ocean tide models have “.tid” Suffix that most of them are prepared by space research center of Texas University. Bernese software applies very well-known gravity models like: GEMT3, GEM- 10N, JGM3, EGM96, TEG4, EIGEN1 and EIGEN2. Bernese software uses these models to calculate the position of moon, sun and other planets.Since, the binary format of these models are not free, Bernese software uses a tool to convert numeral format of these models into binary format of Bernese. Applied models by Ashtech Solutions Commercial Software for ProcessingParameters and cases which should be set and investigated before processing in Ashtech Solutions software are mentioned in Table 2.3.3. Applied Models by LGO Commercial Software for ProcessingParameters and cases that should be set and investigated before processing by LGO software are mentioned in Table 1.Table 1.Applied models by LGO commercial software for processing.3.2. But if the length of network is short, L1 + L2 frequency is used that reduces the errors.3.1. In commercial software, we tune the ionosphere error model in automatic state that if the length of network is large, L3 frequency will be used that in this condition, the ionosphere error would be deleted thoroughly but the problem of this work is that the noise is very much. Applied Models in Commercial SoftwaresAs mentioned before, in scientific softwares, we don’t have any ionospheric and tropospheric errors and the software calculates them scientifically but in commercial softwares, we decrease or omit them by models. Tehran’s real-time positioning stations are designed in a way that can cover all 22 regions of Tehran city.
