Q:What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?

If it's just a GPS meter and a GPS meter, that's a thing.If the measuring instrument, it is not the same with the measured mu instrument.In fact, these GPS is actually said handheld gps.It is used in measuring area and used in agriculture, forestry and animal husbandry.Handheld GPS generally have the function of measuring area.For example, Magellan, Gao Tianxiang handheld GPS etc. These are very famous, each model has the function of measuring areaWe have some stores!

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?

1. GPS is a geodetic instrument, with an accuracy of CM, generally for the millimeter,,Divided into (1) pure static type, such as the South Star of the North Star, the accuracy of mm, now the basic domestic,,(2) RTK, RTK can do is use, carrier phase measurement, the precision is cm level, RTK mobile station must have the control hand book, like television and remote similar, but now there are a lot of hand book can be used as handset2. The handset is generally rough field positioning equipment, navigation for mobile phone use, the general size, precision grade m, now can to about 20cm, and can be used for RTK mobile station use (need to access the base station) can reach cm level.Surveying and mapping qualification applications require geodetic measurement equipment, that is, 1.Now domestic GPS, such as the Haida, the south, China, etc. can be measured, not expensive

Q:Handheld GPS buried in the soil there is a signal

It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects

Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.

If you can join the CORS network, the accuracy of decimeter to centimeter level.

Q:How about the accuracy of the GPS handset?

zhonghaida Qmini series: 3 meters; zhonghaida Qcool series: 5 meters; precision and price is proportional to the precision is higher, the higher the price.

Q:I just bought a handheld GPS Magellan No. 1, showing the latitude and longitude coordinates, I want to set the geodetic coordinates of latitude and longitude, do not know where to set, I would like to ask you, how to set, there is a better picture shows the best, thank you so much.Magellan GPS 210 is not 2000 shy

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:Seeking the similarities and differences between RTK and GPS

RTK full name is GPS-RTK real-time dynamic distribution, which you know.

Q:Can a handheld navigator connect a cell phone? Thank you

Open the phone hotspot WiFi, handheld navigator connected to this wifi.

Q:Handheld GPS and mobile phone GPS what is the difference?

The same: GPS main chip may be the same; can complete the GPS positioning;

Q:Fuxin coordinates with the mapping of the seven parameters are what ah there is no professional knowledge to tell my brother I need to fill the gps... Thanks.

Handheld GPS has not been used, you can find three known control points, try to solve.
