- Q: What factors affect the handheld GPS receive signal?
- Active ionosphere, large canopy, high voltage wire, high building.... Have influence.
- Q: I would like to ask the GPS handset and GPS receiver (Surveying and mapping qualification application needs) is there a difference? If yes, what is the difference?
- This is the case, GPS handheld refers to a thin hand, while the GPS receiver refers to the RTK host, equivalent to the base station in our industry said. The general application of Surveying and mapping qualifications are required for this application, referred to as RTK (1+1) set, level, theodolite, total station, walkie talkie, technical personnel.... And so on, are essential equipment.
- Q: Handheld GPS how to achieve decimeter
- Hello A GPS is not up to the requirements of the class, if no one can buy that expensive submeter GPS, currently on the market with the best precision is GPS, is Derek GARMIN this year a new eTrex 10, 20 and 30, the three can be reached within 3 meters accuracy, you can look at

- 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, the measurement of arable land, fixed point and circle test, which is more accurate,
- If the area is measured, are almost. However, if the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.
- Q: What is the difference between professional navigation and professional GPS navigator
- 1 high precision, good signal.Now GPS hardware precision is about 10 meters, the difference should be small. The accuracy of the practical application is also affected by the electronic map software. Signal does have good or bad, mainly in the fast positioning is not fast, stable, etc..2 long standby time, voice prompt.Standby time mainly to consider two factors. First, the battery capacity is large, two is the best battery is replaceable. PDA class GPS and vehicle navigation generally have voice prompts. This voice prompt is realized by navigation software.
