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:Fuxin coordinates with the mapping of the seven parameters are what ah
Three translation parameters Delta X, Delta Y, Delta Z, three rotation parameter w X, Omega Y, Omega Z and a zoom M, these parameters need to be calculated in a fixed point under different ellipsoid!
Q:Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,
If the measurement point is only the case, the dynamic GPS is now the general error can be guaranteed within 3cm, the total station can be guaranteed to the millimeter.
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:The future of GPS? Who can tell me professional, humane business prospects,
Mainly for the ship, automobile, aircraft and other moving objects positioning navigation. For example:1 ocean navigation and incoming water diversion2 aircraft route guidance and approach landing3 vehicle autonomous navigation4 ground vehicle tracking and urban intelligent traffic management5 emergency rescue
Q:Professional handheld GPS GARMIN (DR) how to use
Look at the functional machine should use the instructions
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: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: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. At the time, location, navigation and other comprehensive applications, Unistrong successful implementation of hundreds of large projects, services in many national key projects, won the national honor.MagellanGarmin
Q:Handheld GPS need to put the phone card?
Hello, now the general GPS are required to put the card! Thanks
