Q:What do you need to test for GPS?
5.DGPS you know, differential GPS (DGPS) positioning accuracy is very high, some GPS equipment providers set up a DGPS transmitter in some areas, free of charge to its customers, if customers are buying GPS receivers with DGPS function. The DGPS transmitter is a fixed GPS receiver (in a 100km ~ 200km exploration scene in the radius setting) receive satellite signals, it knows exactly what is the exact time of transmitting satellite signal to the theory, and then compare it with the actual delivery time, then calculate the "difference", influence this is very close to the atmospheric refraction, it will send out the difference, usually with FM (FM) radio data transmission using subcarrier modulation signal in the baseband receiver, GPS and DGPS function can receive and use it more accurate positioning.
Q:Handheld GPS purchaseHandheld GPS navigator!
Many outdoor enthusiasts are used to this, hiking, cycling and other applications are relatively wide, is an American brand, Mr Zelen back to U.S. Army GPS, and as Ma Ying-Jeou ring when riding on the handlebars also put a good 60CSX. the two brands in the nature, the price is more expensive, are in more than 2000, but the best is to the store to buy.

Q:The future of GPS? Who can tell me professional, humane business prospects,
6 people travel and adventure7 personal communication terminal (with mobile phones, PDA, electronic map integration)8 time synchronization of electric power, post and telecommunication9 accurate timing of admission10 accurate frequency of admission
Q:Mountaineering to buy a professional GPS or Mountaineering Watch
There is no need to buy too many devices. Now the phone is an essential tool, the phone has GPS,
Q:Hand held GPS coordinate conversion method
By the 84 coordinates to Beijing 54 Coordinate. A collection of application area of high grade control data in GPS receiver applied earth area (such as a county) find three (or more) uniform grade (accuracy better) or GPS "B" dot, point the best is around without interference of electromagnetic wave, vision, satellite signal. To the local surveying and mapping management department (such as: the local bureau of Surveying and mapping, surveying and Mapping Institute) Gauss plane coordinate copy these points of the Beijing 54 Coordinate System (x, y), the elevation of H and WGS-84 coordinates of the geodetic coordinates (B, L), the high H.
Q:Professional handheld GPS GARMIN (DR) how to use
Handheld GPS purposes, the measurement of soil area, linear navigation, auxiliary fishing waypoint navigation point information, traffic data display, such as the use of functional machines should be used manual
Q:Handheld GPS positioning, can be directly uploaded to the computer,
The main function of Siwei Hin GPS map tag software1 support Google online (offline) hybrid satellite maps and general maps.2 support 1-18 level map arbitrary scaling, the left mouse button drag roaming.3 support the name of the query location, you can enter the location of the location after the location of the query.
Q:Ask how to select a google satellite map into a handheld Area GPS
If an ordinary mobile phone GPS, can install Orville interactive map support pre download any regional satellite map, support for offline use.
Q:I would like to ask, handheld GPS (set SIBAO) and land use of the RTK, this error is 20 meters?
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
