Q:What is the difference between a hand-held GPS and a car's onboard navigator
Effect of GPS navigation handheld as vehicle, as the vehicle with what map, the hand-held GPS is mainly used for point positioning, measuring area, high precision, good anti 3, my understanding is that
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 purchaseHandheld GPS navigator!
If it is only used for general tourism, then hundreds of pieces of GPS is enough, go to the computer city to see, there must be sold, or go to your city to look at the outdoor store
Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy

Q:Handheld GPS settings.
Latitude and longitude is the geodetic coordinates, the landlord said to be set up for the use of the projection plane Cartesian coordinates - Beijing 54 or Xi'an, the 80 plane rectangular coordinates it.1 position: [format setting unit - "[] position display format is set to User UTM Grid, and enter the relevant parameters, such as the 3 degree or 6 degree with the area with the central meridian projection, the ratio was 1, that deviation is 500000m, north-south deviation is 0.
Q:Who can recommend me a table under the professional GPS software

Q:What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?
GPS Mu meter also known as land area measuring instrument, handheld meter meter, etc.. Integrated computational methods for understanding and intelligent high precision GPS positioning system, the precise area of the handheld computer system, can realize the irregular area of real-time measurement and dynamic graphical display and intelligent data processing and storage.GPS measurement of the meter is different from the general GPS measuring instrument is based on the latitude and longitude of its area calculation function, general GPS is generally used for positioning.
