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;
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: I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
If the carrier phase measurement function is not available, you have the maximum accuracy of GPS accuracy of 1-10This can only improve the observation environment using SBAS and other ways to improve the accuracy
Q: Handheld GPS and mobile phone GPS what is the difference?
Handheld GPS also supports GPS compass navigation and map navigation as well as other more professional GPS applications; mobile GPS can work with fewer, more consumer grade product applications
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: 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: How about the accuracy of the GPS handset?
zhonghaida Qmini series: 3 meters; zhonghaida Qcool series: 5 meters; precision and price is proportional to the precision is higher, the higher the price.
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
Can only use professional GPS measuring instrument! Magellan and SIBAO!
Q: Magellan GPS handheld why so many people choose not to say that the map is not good
Magellan navigation and positioning company with Taiwan Jia Ming Company as the world's leading outdoor handheld GPS, its product features have their own advantages. General Magellan price will be slightly higher, Derek source may be more, but in recent years, the 2 brands will be on a par with slowly, Magellan with the national topographic map, a detailed map of the vehicle with the navigation package, Derek product price has been lowered. If the old section of the handheld GPS feel Magellan's design is more fashionable, the new Magellan with better Ming products have their own characteristics, mainly to see their own habits and tastes.
Q: I just bought a handheld GPS Magellan No. 1, showing the latitude and longitude coordinates, I want to set the geodetic coordinates of latitude and longitude, do not know where to set, I would like to ask you, how to set, there is a better picture shows the best, thank you so much.Magellan GPS 210 is not 2000 shy
Latitude and longitude is the geodetic coordinates, the landlord said to be set up for the use of the projection plane Cartesian coordinates - Beijing 54 or Xi'an, the 80 plane rectangular coordinates it.1 position: [format setting unit - "[] position display format is set to User UTM Grid, and enter the relevant parameters, such as the 3 degree or 6 degree with the area with the central meridian projection, the ratio was 1, that deviation is 500000m, north-south deviation is 0.
