Q: What factors affect the handheld GPS receive signal?: The United States Department of defense. A SA satellite signal to interference (the U.S. government for consideration of security of civil code of a called "selective availability (Selective SA Availability)" interference, to ensure the best protection system is effective. Because of the random error information added by SA in the navigation message, the positioning accuracy of the civil signal C/A code is reduced to about 100 meters. However, the use of differential GPS technology, the system error can be reduced to 10 to 15 metersTwo. Weather factors (including sunspots, bad weather, etc.) to reduce the intensity of the received signalThree. In buildings, vehicles, insulation paper, or metal shielding, GPS signal will be reduced or completely lost signal. In open spaces, GPS devices receive the best signal. .

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.

Q: GPS Mu meter which brand is good, handheld high-precision land area measuring instrument: Simple operation, the screen is large, a few buttonsBoot, and then look at the star almost, to find a field, start and then click on the end of a circle, out of the number ofElectricity can alsoPrecision mody... 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: Can you buy a good handheld GPS in China? FiveTrouble master recommended several professional handheld GPS brand, in addition to handheld GPS can speed it? Thank you!!: In fact, the main function is to use navigation as long as the navigation function can be used

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: Handheld GPS brand rankings: SIBAOIn the GNSS coordinate precision and attributes, "SIBAO" has a professional GPS handset, GIS i-PPP GIS, a mobile data collector, GIS, high precision GIS, high precision measurement of RTK complete product structure, to form a comprehensive solution to the spatial information industry scheme. Set of SIBAO products awarded the Beijing independent innovation product identification certificate, satellite navigation and Engineering Excellence Award and other professional awards.
