With more professional and more accurate positioning but are generally used dry batteries or rechargeable batteries not built-in rechargeable battery that is because handheld GPS users are mostly investigation or walk tourists convenient in use and emphasizes there is screen are generally of low power consumption for general color screen can only convey longitude and altitude mobile phone GPS is just a subsidiary function loading car navigation map

Q:Handheld GPS navigation is what? Where to buy handheld GPS navigation, how to select GPS navigation?

Handheld GPS navigator, also known as portable navigator, but also divided into 2 kinds, one is the ordinary PND navigator, you can go to Zhongguancun, the major appliance stores to buy, and the other is the mobile navigation, GPS smart phone is installed in the GPS navigation software can be,The navigator is composed of 2 parts: hardware and navigation software. The navigator on the market is about RMB 600. The brand of Kelid navigation software is usedGPS is a portable handheld navigation navigation products, the market is now very much, most car navigation can be used, the Gps signal is still free to receive satellite signals in the United States, you only need to charge it, map to the sellers in general can be upgraded.

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, together with the exchange of learning, mutual verification, I said that is my experience. Software tells you that the accuracy is handled and limited, especially for some third party software. If you do not limit the scope of the conditions, the limit is too difficult to determine. If the satellite in poor condition, serious occlusion, satellite time difference, let alone ten meters, a few dozen a hundred meters are possible. Under normal circumstances, single point positioning accuracy is about ten meters, of course, sometimes all aspects of the conditions are very good, a few meters are also some. As for the accuracy of the GPS that you say htc10 and tablet computer, to this kind of navigation type GPS, from the respect of the respect that the instrument says, the accuracy should be in 10 meters to 15 meters (all the conditions are all right). Oh exchange!

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:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,

If the area is measured, are almost. However, if the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.

Q:How to upgrade handheld navigator

Recommend the use of mobile map navigation.Chasing the answerEasy upgrade.

Q:The navigation module it is "selph" three generation? Another one I mainly use it to measure the land area, easy to use, the error is not big?I want to buy Magellan 500 do not know whether it is good to use
