GPS coordinates of property line
Affected by a variety of GPS jammers factors, the surveying and mapping accuracy has not been able to be greatly improved. Therefore, people began to make efforts to further improve the surveying and mapping accuracy from the aspects of surveying and mapping equipment and surveying and mapping technology.
The factors affecting the accuracy of surveying and mapping in GPS land surveying and mapping technology are analyzed. Considering that factors such as satellites, signal propagation paths and reception will affect the accuracy of surveying and mapping, it is proposed to improve the surveying and mapping machine, improve the surveying technology, and strengthen the calculation of surveying and mapping data. Optimizing land surveying and mapping points, etc., and related measures to improve surveying and mapping accuracy, provide an effective reference for improving surveying and mapping accuracy.
4 Bands 1.2W with Ni-Mh battery 2000Mah, Working around 1.5 Hours Support use while battery charging.Shielding radius: (1-10) meters at -75dBm with omni hidden antennas.Could be used in car directly with USB charge cable.Pocket design look like the mobile phone power bank.
Although this type of jammer looks a little bulky, But It can effectively jamming 2G 3G 4G cell phone signals.18W power , jamming range up to 40 meters . Is a very cost-effective jamming device. Designed for the latest 5.8G signal, it can effectively block 5G mobile phone signals.
As the newest military-grade product, the advantages of this jammer are obvious. It has the characteristics of large jamming range and multiple jamming frequencies bands.
