- Q: GPS Mu meter which brand is good, handheld high-precision land area measuring instrument
- A German born mu can also recommend a good precision measuring instrument.
- Q: My friend is in use, the difference is not big, professional handset (smart or Magellan bulky, but 3 case), but the price is expensive, but can not call and map is very rotten, endurance of 10 hours (dry battery) the mobile phone also has all the time. Know friends say, I mainly in the suburbs! Thanks
- Two, different hardware configurationAs the field work environment is relatively poor, so waterproof, dustproof, shockproof for handheld GPS is very necessary. Handheld GPS on the market level of water is generally IPX7, and the continuous use of time is often more than 10 hours. Mobile phones are not so much demand. Handheld GPS function is relatively simple, and even most of the products are still grayscale display screen, multimedia features almost No.In the chip, there is not much difference between the GPS and GPS handheld mobile phone, mobile phone is commonly used in the Samsung 2440 chip and SIRF III receiving module on the handset is also very common, but in recent years MSTAR from Taiwan due to its advantages of cheap, very popular in the low-end handset.
- Q: I am ready to go to the field to go to college, but I do not know how to buy a handheld GPS, I hope you recommend. The most important thing is easy to carry.
- Is not a professional geography or geological personnel, there is no need to use Garmin ah Magellan what ah, you do not need. Using a mobile phone that can accept GPS signals is enough, free software and maps can be found on the internet. On the market a lot of 2000 yuan or so of the phone has this feature, remember that the phone has GPS signal acceptance, not GPRS oh!
- Q: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
- If you can join the CORS network, the accuracy of decimeter to centimeter level.
- Q: Hand held GPS coordinate conversion method
- Three parameter test DX, DY, DZ, DA, DF after the conversion parameters of the five, must be prompted to enter the handheld GPS, while the input area of the central meridian longitude. E on behalf of the east longitude, projection ratio of 1, the deviation of things to the north and south of the deviation of 0, and set the unit for M. Enter these parameters, should be taken to the field test, check whether these five parameters are correct. The method is selected, vision, GPS receiving signal strength of the feature points in the field (such as linear object intersections, independent features, etc.) is the best stone control points were measured and compared with theory and find out the coordinates of these points. If the results of the comparison exceed the nominal accuracy of the instrument, the conversion parameters or the problems that should be found should be recalculated.
- 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 do I still stay in the GPS navigation, GPS monitoring of the primary idea? FiveBusiness services, thank you!Future business services
- 1 power, telecommunications, telecommunications and other network time synchronization2 accurate timing of admission3 accurate frequency of admission1 geodetic measurements of various levels2 Road and various line lofting3 underwater topographic survey4 crustal deformation measurement, dam and large building deformation monitoring5.GIS application6 construction machinery (tyre crane, bulldozer, etc.) control7 precision agricultureAt the present stage, it is mainly used for the security of vehicles and the management of personnel vehicles. With the continuous development of social economy, more and more vehicle users, GPS will gradually get wide application, on the stage of the car is enough for your service. Prospects can still be Lin Shijie GPS
- Q: Welcome to make comments on the existing GPS tour pal what shortcomings to answer the more detailed the better
- Fifth elements: the terrain map is the main project of outdoor sports climbing, mountain climbing is very exhausting, we usually do a plan will be completed on schedule, a good plan should be to our destination in the manual run out before. And if you want to do this, it must be on the road difficult to have a correct anticipation. But this time, with the terrain map GPS can come in handy, the mountains and the altitude of the understanding, we need to know about these sections spend much time and energy. And the general GPS map, is unable to meet the needs. So we'd better buy a map with contour terrain data of professional grade GPS, make your own outdoor journey do in our hands.
