Q:How to set the handheld GPS related parameters and coordinate conversion parameters throughout the country
Two. To coordinate the coordinate data of the control points obtained provide technical support unit of Beijing Unistrong companies around the branch responsible person to calculate the coordinate transformation parameters conversion parameters, or to obtain their own conversion conversion software. After the conversion parameters are calculated by the prompt input handheld GPS. Only after such a setup, after all the soil in the region when the coordinates of the GPS read out the coordinates of the point for the Beijing 54 coordinates.
Q:Handheld GPS can be used for mountain terrain 1:2000 topographic mapping
It is really unexpected, basically not, the accuracy is not enough!
Q:Handheld GPS charge is not into electricity what is the reason
Two, solutions:1, for other chargers, or data lines try, or clean the charging port.2, boot into recover mode advancsd advanced mode, select the wipe Battery, remove battery traces.
Q:Who can recommend me a table under the professional GPS software
SOSO map is good, I use this.Kelid navigation is also good.
Q:How to hand GPS eTrex H data to the computer
"Shaanxi skmax navigation information Limited" GARMIN proxy (GARMIN official website can be found), contact (Xiao Hou) the hope can help to you, if you do not understand what we see on the Internet, may at any time, contact us!
Q:Handheld GPS each brand is what the difference between different prices in the
Engage in measurement and what is the difference between the car I do not know, look at the car to see if the functionSMS + Mobile Internet + computer network platform! 3 ways to check the car!
Q:What do you need to test for GPS?
As a high-tech product, GPS has a very complex technical parameters. However, as people's living standards improved rapidly, more and more ordinary people began to pay attention to the positioning and navigation tools originated from the military. Because the convenience it brings is unprecedented. In order to let everyone out of all the technical parameters of GPS receiver, no longer confused at the time of purchase, the author selected six of the most important technical indicators, one by one to explain to you. 1 parallel channels on the market most of the GPS receiver is a 8 channel, 12 channel, the 16 channel, which allows them to continuously track the information of each satellite. Some GPS devices only have 2 to 5 parallel channel receiving satellite signals, because the average of 8 satellites are visible, which means that the GPS receiver must visit each of the satellites in order to obtain information about each satellite. All of our products are in Shenzhen channel 16 channel, multi-channel parallel GPS receiver, including the advantages of rapid cold start and initialization of satellite information, but also in the forest area can have a better reception. General 12 channel receiver does not require an external antenna, unless you are in a bad environment conditions such as closed space, such as the cabin, the car. 2 the sensitivity of the GPS satellite signal to the ground has been very weak, as well as ground wireless communication clutter interference. The lowest traceable signal strength of the GPS receiver determines how much useful signal is received. A GPS receiver with a lower minimum tracking signal strength has a higher sensitivity, and can receive more available satellites under bad conditions
Q:Handheld GPS buried in the soil there is a signal
It depends on how deep you buried the darker the GPS signal, and must ensure that the GPS antenna upward, the above can not be covered with metal objects
Q:What is GPS Mu meter ah, with the general said that the GPS measuring instrument what is the difference?
The amount of words on the handheld GPS, Magellan can be both economic and affordable.
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.
