At the start of the article, we'd like to mention sorry to everyone, because within the original plan, we'll explain the answer to the host problem during RTK rover setup process during this article. During the writing process, it had been found that the answer of RTK rover was basically an equivalent because the solution of the RTK base station within the previous article, so we didn't describe the answer of rover intimately. I think that everybody will solve the matter easily after studying the content of the previous article.
Additional point:
What must be reminded here is that in radio mode, the coverage range of the overall external radio is a smaller amount than 20km, and therefore the coverage of the built-in radio is a smaller amount than 5km. the precise situation depends on the particular area and terrain.
One more tip:
If your receiver has an abnormal voice broadcast, you'll troubleshoot and solve the matter from the subsequent aspects.
In the external radio mode, check whether the external radio aerial is just too on the brink of the host and cause interference. We recommend that the transmitting antenna got to be a minimum of two meters faraway from the most unit; within the built-in radio mode, check whether an extension pole is employed to isolate the base of the tripod and therefore the main unit (the built-in radio aerial can't be in touch with the metal object on the base or the tripod), Thereby reducing the interference of metal objects on radio transmission.
If necessary, you'll remove the battery of the most unit, place it on a metal object (to discharge static electricity), then reinstall it and switch it on.
That’s all.

In daily RTK surveying and mapping work, the matter of "no fixed" within the radio mode plagues many surveying and mapping personnel, affecting measurement accuracy and measurement work progress.
We glance for the breakthrough of the matter from the three aspects of RTK base station, RTK rover and link, which can assist you find how to unravel the matter to RTK quickly.Solution for the base station:From the signal transmitted by the satellite to the signal received by the receiver, there's interference from the ionosphere, troposphere, and multipath effects, leading to weak signals.
The base station should be found out during a place with good viewing space, distant from strong electromagnetic interference sources (such as high-voltage lines, signal towers, etc.).
round the base station to scale back the impact of multipath effects.
Additionally, the radio aerial should be set at a distance of quite 2 meters from the base station to avoid UHF electromagnetic radiation interference.Solution for the rover:When the space between two points on the base is brief, the system can simulate the consequences of the ionosphere and troposphere, and therefore the residual effects also can be eliminated or reduced by differential processing of observations.
However, drastic changes may occur within the air at any time, and therefore the satellite signals will have varying degrees of impact during they reach base stations and mobile stations, and the longer the baseline, the greater the impact.
Each scan takes approximately six minutes using the right settings, during which era a surveyor can capture a strip of sidewalk, building corners, or some paint striping also as everything it sees during a 1,000ft.
By capturing everything, and doing it at a consistent rate, the quantity of things to be included became irrelevant to our field time.
We simply captured the situation and allowed the drafter to document what was needed.Total Station is an electronic/optical device that uses laser signals to figure out precise locations (to within about half a centimetre).Until the whole Station was developed, surveying was through with theodolites which measured angles only, and three-dimensional surveying was only possible within the very limited range of traditional distance measurement which meant hand measurement with surveying tapes.
The Uses Of Total StationTo begin, the whole Station device stands on a tripod at a neighborhood on the land and sends a distance measuring beam (laser or, as in our case, infra-red) onto special reflective material placed at prominent points, mentioned as ‘control points’, that are very carefully surveyed.
Total Station Various StagesTotal Station surveying has been done at various stages of the Zagora Archaeological Project, and thus the results of the survey are being relied upon to work out locations throughout the situation ,and to form sure the precise location of any trenches to be dug and building structures or artefacts that are uncovered during excavation.The great advantage of the whole Station is that the speed and accuracy of determining location.
It doesn’t actually do anything a tape and a theodolite couldn’t do – but it does it far more easily and accurately.The total stations take single-point measurements.
