Q: What factors affect the handheld GPS receive signal?: Active ionosphere, large canopy, high voltage wire, high building.... Have influence.

Q: Handheld GPS positioning, can be directly uploaded to the computer, and the computer has a scalable map to mark the upload point. The above system, now there are 20Such as the title, I want to achieve the final function: through the manual to a point, with a hand-held GPS locator will be recorded in the specific latitude and longitude, and sent to the network in real time, for my computer to mark these points on the map. If you can directly enter the site of some of the information, directly to the above is the bestIf you have the above equipment, please indicate the scientific name, and the specific application industry.Thanks.: 13 support GPS satellite positioning function, the need to connect GPS satellite positioning hardware devices (USB GPS devices or Bluetooth GPS devices; tablet PC).14 support offline map pack custom download function, you can download the map anywhere in the world.

With a special RTK or not, but what is sure to measure a circleFlat measurement of quasi accurate, biased on what is almost, it can be accepted

Q: How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country: 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: What is the difference between professional GPS handsets and mobile navigation?: GPS is the most important positioning accuracy. 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.

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: 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.

Q: What qualifications should a normal GPS locator have?: You ask is handheld GPS, it is the manufacturer's qualification requirements or what. For example, business license, tax registration certificate, organization code certificate, vendor authorization, software copyright, precision test report, 3C certificate, ISO9001, industrial grade IP certificate and other relevant qualification certificates and documents

Q: What is the difference between professional navigation and professional GPS navigator: 3 map software is accurate, you can identify the road on the viaduct, and you can tip up and down viaduct."This should be no problem currently on the market of the navigation software is mainly three: Skywalker, Kai Lide, cityonmap. Three navigation software has its own advantages and disadvantages. I personally feel that the person with Skywalker more, some car navigation systems (non open operating system) OEM software with Kay more than cityonmap map Skywalker is better but the interface is not good.4 mobile phone PDA load or other independent GPS devices can be.
