- 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: 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: Seeking the similarities and differences between RTK and GPS
- GPS is a satellite system of the United States, is a kind of GNSS, GPS is widely used in surveying and mapping, the use of static and dynamic, RTD, dynamic RTK, RTK is a real-time dynamic difference, the accuracy of centimeter level, that is to say RTK is a GPS application method
- Q: What is the difference between professional GPS handsets and mobile navigation?
- First of all, if used outdoors, then fell, and so on are likely to water, and this thing is also very expensive, so the opportunity to have a high professional anti shock waterproof performance. You can see the Challenger I tour the next 600, three well plates.
- Q: Jia Ming etre20 handheld GPS good
- The new generation of the eTrex series is the first generation of user level receivers that can track both GPS and GLONASS satellites. GLONASS global navigation satellite system developed by Russian Federation, fully put into use. When using the GLONASS satellite, the average time for the receiver to lock the target is about 20% faster than GPS. And, when using both GPS and GLONASS, the receiver has the ability to lock more than 24 satellites as compared to GPS alone.
- Q: Handheld GPS which brand is good
- Now GPS can also do handheld measurement accuracy, precision can usually reach decimeter level, the industry there are relatively well-known Huace, professional GPS measurement instrument, high precision of handheld GPS the good.
- Q: How do I still stay in the GPS navigation, GPS monitoring of the primary idea? FiveBusiness services, thank you!Future business services
- 1 power, telecommunications, telecommunications and other network time synchronization2 accurate timing of admission3 accurate frequency of admission1 geodetic measurements of various levels2 Road and various line lofting3 underwater topographic survey4 crustal deformation measurement, dam and large building deformation monitoring5.GIS application6 construction machinery (tyre crane, bulldozer, etc.) control7 precision agricultureAt the present stage, it is mainly used for the security of vehicles and the management of personnel vehicles. With the continuous development of social economy, more and more vehicle users, GPS will gradually get wide application, on the stage of the car is enough for your service. Prospects can still be Lin Shijie GPS
- 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: I just bought a handheld GPS Magellan No. 1, showing the latitude and longitude coordinates, I want to set the geodetic coordinates of latitude and longitude, do not know where to set, I would like to ask you, how to set, there is a better picture shows the best, thank you so much.Magellan GPS 210 is not 2000 shy
- Latitude and longitude is the geodetic coordinates, the landlord said to be set up for the use of the projection plane Cartesian coordinates - Beijing 54 or Xi'an, the 80 plane rectangular coordinates it.1 position: [format setting unit - "[] position display format is set to User UTM Grid, and enter the relevant parameters, such as the 3 degree or 6 degree with the area with the central meridian projection, the ratio was 1, that deviation is 500000m, north-south deviation is 0.
- Q: Handheld GPS, the measurement of arable land, fixed point and circle test, which is more accurate,
- So for you to measure the area, some of the 3cm point error surrounded by the graphics area and some millimeter level point error surrounded by the graphics area is not much difference.
