- Would like to use the function of handheld GPS purposes, the measurement of soil area, linear navigation, auxiliary fishing waypoint navigation point information, traffic data display, etc.
- 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: Handheld GPS which brand is good
- Now GPS can also do handheld measurement accuracy, precision can usually reach decimeter level, the industry there are relatively well-known Huace, professional GPS measurement instrument, high precision of handheld GPS the good.
- 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: How about the accuracy of the GPS handset?
- Zhonghaida Q1:2 zhonghaida Q5:1 meters; meters; zhonghaida Q6: decimeter; zhonghaida Q8 cm;
- Q: Magellan GPS handheld why so many people choose not to say that the map is not good
- Select the right access to GPS oh it has a contact information users
- 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?
- The more high-end is good, clever and wheat zalun, many outdoor enthusiasts are used to this, hiking, cycling and other applications are relatively wide, is an American brand, Mazelen returned to the U.S. Army GPS, and as Ma Ying-Jeou ring when riding on the handlebar also puts a high out of this two 60CSX. the brand in the nature, the price is more expensive, in more than 2000, but the best is to the store to buy.
