Q:What do you need to test for GPS?: 3 positioning time this means when you restart your GPS receiver, it determines the time required for the current position. For the 12 channel receiver, if you are in the last position near the location of the cold start time is 30 seconds to 5 minutes, hot start is usually 5 to 40 seconds, and for the 2 channel receiver, most of the cold start more than 15 minutes, hot start 2 to 5 minutes. 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,

With conventional measurement methods, often adopt the measure to increase the number of methods to extend the observation time, time consumption and labor consumption to try to improve the accuracy of.2, the long tunnel and bridge for the complex terrain region difficult, conventional control measure for visibility and network shape, often cut down the workload is quite large, so the measurement of the cost of a large, hard work.Link control network of high precision 3, long tunnel and bridge and low precision and route network, although with adjustment methods can be overcome, but because of the terrain conditions are difficult, the measurement workload to its connection, and is not too easy. In practical work, the control of the structure and the measurement of the route are often out of touch.

Q:Handheld GPS positioning, can be directly uploaded to the computer, and the computer has a scalable map to mark the upload point.
