Q:What do you need to test for GPS?: 6 antenna type to give you a good positioning, GPS receiver requires at least 3 ~ 5 satellites are visible. If you are in a canyon or on both sides of the street, or in the dense jungle, you may not be able to contact with enough satellites, so that you can not locate or only two-dimensional coordinates. Also, if you're in a building inside, you may not be able to update your location, some GPS receivers have a separate antenna can be attached to the windshield, or built-in active antenna, or an external active antenna can be placed on the roof, the receiver which helps you get more satellite signals the. 7 other indicators to buy GPS equipment, according to the needs and use of the environment, size, weight, waterproof, shockproof, dustproof performance, high temperature resistance, power consumption and other indicators should be taken into account.

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:In addition to the parameters, that is the problem of the machine, what method can reduce the error of these two machines to a minimum. Because, at the same time to find a coordinate. The gap is too big.: GPS was in error with 10 meters, with the star search results, related to the environment, if the precision is high, as long as the use of handheld GPS submeter or handheld RTK

Q:Handheld GPS locator measuring accuracy is about how many meters?: The handheld machine precision is generally divided into: centimeter decimeter level, 1 meters, 2 meters, 3 meters, 5 meters; the precision is higher, the higher the price.

Q:Fuxin coordinates with the mapping of the seven parameters are what ah there is no professional knowledge to tell my brother I need to fill the gps... Thanks.: Handheld GPS has not been used, you can find three known control points, try to solve.

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:Handheld GPS brand rankings: Set of SIBAO products awarded the Beijing independent innovation product identification certificate, satellite navigation and Engineering Excellence Award and other professional awards. At the time, location, navigation and other comprehensive applications, Unistrong successful implementation of hundreds of large projects, services in many national key projects, won the national honor.
