- 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: Mountaineering to buy a professional GPS or Mountaineering Watch
- Can be downloaded in general maps, satellite maps, and even contour maps, which features far more than handheld GPS or mountain climbing watches, you can better meet the needs of mountaineering.
- 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.
- 10 meters.To the world in 2013 a total of four global satellite navigation system, in addition to the United States has been in the mature GPS system and commercial operation, the Beidou system, China the European Galileo system, the Russian GLONASS system are still under construction. "The Galileo satellite navigation project" was first conceived by the 30 satellite GPS network to compete with the United States, the beginning of the design proposed in 2008 formally put into operation, and later postponed to 2014, the entire system is only 4 satellites in orbit (as of 2012), in fact it is mainly used to further verify the relevant design and the working system of the system design, after the official start of Galileo satellite will launch. Formal networking satellites are being prepared. China satellite navigation system management office senior engineer Yang Qiangwen introduction, to 2012, the "system" in orbit satellites are also only verify satellite.
- Q: GPS handheld function to measure it?
- If the construction survey is certainly not the case, the control measurement is possible
- Q: Handheld GPS and mobile phone GPS what is the difference?
- Different: antenna size, function, accuracy, protection level, and has been different in the application layer (handheld GPS support GPS compass navigation and map navigation and other more professional GPS applications);
- Q: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy
- Look at the maximum accuracy of GPSIf the difference accuracy can reach 1cm you can connect CORS single base station and other network RTK way to achieve the corresponding accuracy
- Q: Saying that we have a project in front of it is to do so, it is surprising that there are wood
- It is really unexpected, basically not, the accuracy is not enough!
- 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
- Professional handheld GPS only Magellan and set SIBAO
- Q: What is the difference between professional navigation and professional GPS navigator
- 5 price of less than 3000 yuan.> 4, 5 a answer: there are PDAGPS mobile phone development, but should be more than 6000. One of the PDAGPS generally above 3000, generally have more than 3000 car navigation. If you have Bluetooth support PDA or PDA phone, plus a Bluetooth GPS is as long as 1000 or so. So the first three choices and then you have only the following three choices: first, the new machine but the older models, businesses dumped, and the other is to know the people, and the three is a vintage.More well-known brands in the market: Taiwan (MIO), the new branch, Taiwan HOLUX long days, GARMIN, HP, etc.PDAGPS mobile phone: MIO A700, E, TATO588, HP6515PDAGPS development: MIO168, 169, 269, P350, HOLUX PolarisVehicle navigation: MIO C210, new section four or five, GARMIN three or four
