Q:How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Collect the application area of high grade control data in GPS receiver applied earth area (such as a county) find three (or more) uniform grade (accuracy better) or GPS "B" network, the best point is around without interference of electromagnetic wave, vision, the satellite signal is strong. To the local surveying and mapping management department (such as: the local bureau of Surveying and mapping, surveying and Mapping Institute) Gauss plane coordinate copy these points of the Beijing 54 Coordinate System (x, y), the elevation of H and WGS-84 coordinates of the geodetic coordinates (B, L), the high H.
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!

The positioning accuracy of the positioning accuracy of 4 which is obtained in the case of no WAAS/EGNOS conclusion, rather than most of the GPS receiver specification of the positioning accuracy, can look at the test report of others so before the purchase of GPS, now on the market with 12 channel GPS receiver error level is generally not more than 30 meters, height error not more than 50 meters, the average error is about 15 meters. Due to the use of the module, our product positioning error is about 10 meters,
