Q:How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Three parameter test DX, DY, DZ, DA, DF after the conversion parameters of the five, must be prompted to enter the handheld GPS, while the input area of the central meridian longitude. E on behalf of the east longitude, projection ratio of 1, the deviation of things to the north and south of the deviation of 0, and set the unit for M. Enter these parameters, should be taken to the field test, check whether these five parameters are correct. The method is selected, vision, GPS receiving signal strength of the feature points in the field (such as linear object intersections, independent features, etc.) is the best stone control points were measured and compared with theory and find out the coordinates of these points. If the results of the comparison exceed the nominal accuracy of the instrument, the conversion parameters or the problems that should be found should be recalculated.
Q:Handheld GPS need to put the phone card?
Travel GPS professional solutions:Put card. Will be equipped with a card at the time of purchase.

6 antenna type to give you a good positioning, GPS receiver requires at least 3 ~ 5 satellites are visible. If you are in a canyon or on both sides of the street, or in the dense jungle, you may not be able to contact with enough satellites, so that you can not locate or only two-dimensional coordinates. Also, if you're in a building inside, you may not be able to update your location, some GPS receivers have a separate antenna can be attached to the windshield, or built-in active antenna, or an external active antenna can be placed on the roof, the receiver which helps you get more satellite signals the. 7 other indicators to buy GPS equipment, according to the needs and use of the environment, size, weight, waterproof, shockproof, dustproof performance, high temperature resistance, power consumption and other indicators should be taken into account.
Q:GPS handheld function to measure it?
Depends on the accuracy of the range you require, if the accuracy of the 3-5 meter can be used for ranging, measuring area, latitude and longitude, elevation information, etc.
