Q: Is it accurate to measure highway mileage with GPS handheld
Measuring mileage, since the unit has been upgraded to the inside, it is quite accurate oh
Q: Seeking the similarities and differences between RTK and GPS
GPS is a satellite system of the United States, is a kind of GNSS, GPS is widely used in surveying and mapping, the use of static and dynamic, RTD, dynamic RTK, RTK is a real-time dynamic difference, the accuracy of centimeter level, that is to say RTK is a GPS application method
Q: What is the difference between industrial GPS handset and mobile navigation
3, professional handheld machine with industrial design. First of all, if used outdoors, then fell, and so on are likely to water, and this thing is also very expensive, so the opportunity to have a high professional anti shock waterproof performance.4, different screen design. If you look carefully, you can see in the outdoor light, mobile phone can not see the contents of the screen, while the professional handset is not the same, can see clearly in bright light, does not affect the work of foreign trade operations.
Q: What is the difference between the phone's GPS and professional handheld GPS features and differences?
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: Hand held GPS coordinate conversion method
Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.
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 Qmini series: 3 meters; zhonghaida Qcool series: 5 meters; precision and price is proportional to the precision is higher, the higher the price.
Q: How to upgrade handheld navigator
Some 4S shop can;Read the instructions, there are generally USB mouth, then you can upgrade the computer practice;There is a memory card, then you can remove the plug on the computer upgrade;Or get the computer city to see it.
Q: Ask how to select a google satellite map into a handheld Area GPS
If an ordinary mobile phone GPS, can install Orville interactive map support pre download any regional satellite map, support for offline use.
Q: Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,
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.
