While scientific softwares are much more complex and have specific and professional settings that make it too hard to handle them.

Commercial 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. īy 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.

It means that, by short time observations, the determination of dynamic position is possibly prepared and by carrier code signals, the position of rover station is determined with centimeter accuracy immediately. In general, RTK is a process in which GPS signal corrections are communicated from a reference station’s receiver with known position to one or more rover receivers in a real-time strategy. The applications of this method account for: positioning with high accuracy for navigation systems, guiding auto-run machines, unmanned aerial vehicles, marine missions like: dredging and large-scale map’s update. In this method, the user usually is in need of a reference station which is located at maximum 10 km distance, in order to determine the position with centimeter accuracy. In the middle of 1990s, GPS inventors introduced Real-Time Kinematic (RTK) method, that by means of it, we can achieve the desirable accuracies in surveying. To do so, we choose a GPS network from Tehran city and discussed it, in order to evaluate the measured accuracy for baselines and also coordinate system that after data processing, it was understood that if the polygon of a network is small, commercial softwares can be utilized with very high acceptable accuracies and even by Ephemerides Precise data, their accuracy will increase more, but if our network is more extended and bigger, there is no other choice except using scientific softwares to calculate coordinate that performs a processing by many parameters.

We have considered accuracy and validity of scientific software, which gives acceptable results, as a baseline to see how much errors and difference is between this software and the commercial softwares, so we selected Bernese as a scientific software and LGO, Ashtech Solutions, CGO softwares as commercial softwares and we analyzed them and compared the applied models of the softwares with each other. In this article, we compared a series of softwares which engineers use for their data processing with powerful scientific software that meanwhile it is too hard and time consuming to learn it. The most outstanding issue is that, it should be understood, the application of which kinds of softwares will help us to gain the desirable accuracy and whether the accuracy of coordinate estimation is acceptable in all commercial softwares or not. The engineers use various softwares for observation processing and GPS networks, generally everyone who uses a device, he uses softwares with the same brand for the processing of it GPS processing networks by defined default parameters and models.

I noticed in a project that one setup was misaligned by a few inches despite the error statistics being good.

I've also learned that careful visual inspection of the registration is most important. Absolutely 0 even if I increase the number of decimal places. Then there are results I don't understand such as when the error is 0.000. I recall being told less than 0.03 ft error is acceptable.

It would be useful for me to understand how I can change my field technique to improve the error statistics. I will also try to get a more specific definition when I take the training some time in the next few months. I have unused training sessions with Leica. Some of the definitions just use the same word defined in the definition.Īside, for Reg360 cloud to cloud I'm not sure what 'matching geometry of point clouds' means. Anyone know of a quantitative explanation? For the error, error vector, group error, group error vector? I think these statistics are used in Cyclone only.
