Q:How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Collect the 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" network, the best point is around without interference of electromagnetic wave, vision, the satellite signal is strong. 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: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
Q:GPS equipment accuracy and real-time single point positioning accuracy?
You are very normal, the tablet computer and mobile phone antenna, not inside, the highest accuracy is about 10 meters, as ordinary navigation is good enough, to achieve centimeter level accuracy by GPS single is, that is to achieve the RTK measurement, is the application of professional measurement, now RTK or by the United States GPS satellite, not the United States GPS satellite as China Beidou mobile station and the base station is in need of mutual difference calculation to achieve accurate measurement. Now the single can receive SBAS signal, single precision up to 1-2 meters, the Northeast in some places to achieve sub meter level, which is the highest single precision can reach, is also used in field investigation using professional machine.
Q:Can a handheld navigator connect a cell phone? Thank you
Mobile navigator can downloadOther purchases can not beNow basically use the phoneEasy update and operation
Q:Is it accurate to measure highway mileage with GPS handheld
Can only say that the handheld GPS measurement of highway mileage can be a reference, if you want to measure the accuracy or sub meter level or professional measuring tools better
Q:Handheld GPS purchaseHandheld GPS navigator!
If it is only used for general tourism, then hundreds of pieces of GPS is enough, go to the computer city to see, there must be sold, or go to your city to look at the outdoor store
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:Recommend a handheld GPS
Younger brother, buy a smart phone, ranging from several hundred dollars to several thousand dollars, as long as the GPS module on the line, understand it?I'm not talking about it, as long as the smart phone with GPS module, you can use when GPS, can be used to drive, you can certainly use a walk. Even if there is no GPS die fast, with a cell phone signal can be positioned, but not too accurate. Hundreds of meters.In addition, you go to college, do not use smart phones, students are not afraid of jokes? Buy a Android system on the machine line. Cheap on a few hundred dollars.You say you take a hand-held machine, and then take a cell phone to go out, trouble is not trouble?
Q:I am a handheld GPS precision is low, how to use to be able to improve certain accuracy.
If you can join the CORS network, the accuracy of decimeter to centimeter level.
Q:What is the difference between GPS and GPS?
If it is used, there is no difference.
