- Q: Highway measurement with GPS I do not know which of the base station settings and mobile station settings I are very vague, to the instrument to build a coordinate system how to build the relevant issues to me
- For long tunnels, the conventional measurement of large bridges has the following limitations:1, long tunnels, bridges and other structures generally require the measurement level of four or more. With conventional measurement methods, often adopt the measure to increase the number of methods to extend the observation time, time consumption and labor consumption to try to improve the accuracy of.2, the long tunnel and bridge for the complex terrain region difficult, conventional control measure for visibility and network shape, often cut down the workload is quite large, so the measurement of the cost of a large, hard work.Link control network of high precision 3, long tunnel and bridge and low precision and route network, although with adjustment methods can be overcome, but because of the terrain conditions are difficult, the measurement workload to its connection, and is not too easy. In practical work, the control of the structure and the measurement of the route are often out of touch.
- 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?
- This is the case, GPS handheld refers to a thin hand, while the GPS receiver refers to the RTK host, equivalent to the base station in our industry said. The general application of Surveying and mapping qualifications are required for this application, referred to as RTK (1+1) set, level, theodolite, total station, walkie talkie, technical personnel.... And so on, are essential equipment.
- 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: Want to buy handheld GPS in Hongkong, I would like to ask what brand is better, the specific model? Where to buy? How much is the price? In the mainland can be used? More questions, thank you!
- Specific model depends on what you are doing, almost two thousand or three thousand of the words can be. Good point is four thousand to six thousand.
- Q: What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?
- GPS Mu meter also known as land area measuring instrument, handheld meter meter, etc.. Integrated computational methods for understanding and intelligent high precision GPS positioning system, the precise area of the handheld computer system, can realize the irregular area of real-time measurement and dynamic graphical display and intelligent data processing and storage.GPS measurement of the meter is different from the general GPS measuring instrument is based on the latitude and longitude of its area calculation function, general GPS is generally used for positioning.
- 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 do you need to test for GPS?
- 3 positioning time this means when you restart your GPS receiver, it determines the time required for the current position. For the 12 channel receiver, if you are in the last position near the location of the cold start time is 30 seconds to 5 minutes, hot start is usually 5 to 40 seconds, and for the 2 channel receiver, most of the cold start more than 15 minutes, hot start 2 to 5 minutes. The positioning accuracy of the positioning accuracy of 4 which is obtained in the case of no WAAS/EGNOS conclusion, rather than most of the GPS receiver specification of the positioning accuracy, can look at the test report of others so before the purchase of GPS, now on the market with 12 channel GPS receiver error level is generally not more than 30 meters, height error not more than 50 meters, the average error is about 15 meters. Due to the use of the module, our product positioning error is about 10 meters,
- Q: How to hand GPS eTrex H data to the computer
- You have a data cable, the computer installed on the MapSource software, connect the computer and handheld GPS can transfer data!!!"Shaanxi skmax navigation information Limited" GARMIN proxy (GARMIN official website can be found), contact (Xiao Hou) the hope can help to you, if you do not understand what we see on the Internet, may at any time, contact us
