Q:What is the difference between professional GPS handsets and mobile navigation?
Mobile phones are used for network navigation, no network will not work, professional GPS navigation satellite navigation,
Q:Handheld GPS how to achieve decimeter
Look at the handheld chip, and some can be directly achieved, some with differential signals to
Q:Hand held GPS coordinate conversion method
Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.
Q:I bought the way k20s, this handheld GPS how
Choi way handheld GPS feel that you can also be in the last year, the Zhengzhou Bureau of Surveying and mapping seems to be called the wide Han instrument that home to buy, so there is no problem with it, the price is not expensive.
Q:GPS equipment accuracy and real-time single point positioning accuracy?
Oh, together with the exchange of learning, mutual verification, I said that is my experience. Software tells you that the accuracy is handled and limited, especially for some third party software. If you do not limit the scope of the conditions, the limit is too difficult to determine. If the satellite in poor condition, serious occlusion, satellite time difference, let alone ten meters, a few dozen a hundred meters are possible. Under normal circumstances, single point positioning accuracy is about ten meters, of course, sometimes all aspects of the conditions are very good, a few meters are also some. As for the accuracy of the GPS that you say htc10 and tablet computer, to this kind of navigation type GPS, from the respect of the respect that the instrument says, the accuracy should be in 10 meters to 15 meters (all the conditions are all right). Oh exchange!
Q:What is the difference between GPS and GPS?
If it is used, there is no difference.
Q:Handheld GPS buried in the soil there is a signal
It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects
Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy
If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy
Q:Handheld GPS settings.
2 map reference setting: [[map] - unit "benchmark is set to User, and input the DX, DY, DZ, DA, DF parameters, usually DX, DY, DZ vary from region to region, so need to know the high level control points to solve, solving methods are as follows:The handheld GPS is placed in the control point field buried pile, were measured, and then hand coordinate coordinates and the known control points of the GPS measurements obtained for the poor, can be obtained by local coordinates and elevation deviation value: DX, DY, DZ.
Q:Handheld GPS each brand is what the difference between different prices in the
I was engaged in car GPS positioning, the first difference between different prices is the biggest cost of different module determines the price, this is the precise positioning of the key, but also the guarantee of product quality, rather than low-cost copycat version, as a kind of different price mobile phone, why Apple four generation sell so expensive but, only a few hundred to copycat.
