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?: GPS handheld GPS operating manual, GPS receiver is to receive satellite signals, GPS consists of two components.

Q: My friend is in use, the difference is not big, professional handset (smart or Magellan bulky, but 3 case), but the price is expensive, but can not call and map is very rotten, endurance of 10 hours (dry battery) the mobile phone also has all the time. Know friends say, I mainly in the suburbs! Thanks: Two, different hardware configurationAs the field work environment is relatively poor, so waterproof, dustproof, shockproof for handheld GPS is very necessary. Handheld GPS on the market level of water is generally IPX7, and the continuous use of time is often more than 10 hours. Mobile phones are not so much demand. Handheld GPS function is relatively simple, and even most of the products are still grayscale display screen, multimedia features almost No.In the chip, there is not much difference between the GPS and GPS handheld mobile phone, mobile phone is commonly used in the Samsung 2440 chip and SIRF III receiving module on the handset is also very common, but in recent years MSTAR from Taiwan due to its advantages of cheap, very popular in the low-end handset.

Q: I bought the way k20s, this handheld GPS how: Ordinary hand-held GPS is 3-5 meter accuracy, high accuracy can be achieved unless buy submeter ordinary user, if you can.

Q: What is the difference between professional GPS handsets and mobile navigation?: Mobile phones are used for network navigation, no network will not work, professional GPS navigation satellite navigation,

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.

Q: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy: If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy

Q: Saying that we have a project in front of it is to do so, it is surprising that there are wood: It is really unexpected, basically not, the accuracy is not enough!

Q: How to hand GPS eTrex H data to the computer: Computer installed on the MapSource software, connect the data cable, upload waypoints and tracks can be!

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.
