Q:In addition to the parameters, that is the problem of the machine, what method can reduce the error of these two machines to a minimum. Because, at the same time to find a coordinate. The gap is too big.

GPS was in error with 10 meters, with the star search results, related to the environment, if the precision is high, as long as the use of handheld GPS submeter or handheld RTK

Q:Handheld GPS purchaseHandheld GPS navigator!Is mainly used for tourism, I said is not a mobile phone, is a more professional handheld GPS navigator for travel outside! Handheld GPS navigator can voice navigation?

Many outdoor enthusiasts are used to this, hiking, cycling and other applications are relatively wide, is an American brand, Mr Zelen back to U.S. Army GPS, and as Ma Ying-Jeou ring when riding on the handlebars also put a good 60CSX. the two brands in the nature, the price is more expensive, are in more than 2000, but the best is to the store to buy. If only for tourism, generally hundreds of pieces of GPS will be enough, go to computer city to see, must be sold, or go to your city in the outdoor store to see.

Q:Verify the accuracy of the GPS device to buy back, the way is to use Android under the'gps state 'software, to test the accuracy of real-time single point positioning.1 with two sets of the same Android Tablet Computer (custom machine, type of bad) in the same position for receiving, find that the accuracy is the same (software, are 1-2 meters), but the position would be poor 10 meters or more. It's in the same place.The 2 one is the Android tablet computer, a mobile phone is HTC G10, also received together in the same position, find that the accuracy is not the same as (the latter 20 meters or so), but also may be about 10 meters position difference.The accuracy of this GPS device can reach 1-2 meters, while the same location in real-time single point positioning error of 10 meters, a reasonable explanation.

Oh the single point positioning accuracy is about 10 meters, but also have a great relationship with the environment around you, if in the city, the accuracy of twenty meters are possible, if the open place, outside. Ten meters should not be a problem. Whether you use a professional measurement RTK or ordinary navigation handheld machine, single point positioning accuracy can reach 1-2 meters of the machine I is not met, if you see where I wish to share with me, thank you. Can only say that the use of professional measurement RTK will certainly be higher than the navigation accuracy of GPS single point oh
