Does the GPS satellite descend
In 1973, the U.S. Department of Defense launched the GPS project, and in 1978 the first satellites of the Block-I series were launched. In 1989, 9 satellites of the Block-II series were launched. In 1993, 24 satellites were networked and reached full operational capability. The former Soviet Union followed closely, establishing the GLONASS global navigation system in 1982, and in 1996, GPS jammers was fully equipped. operational capability.
Due to the short lifespan of satellites, the number of satellites continued to decline, and by 2002 only seven satellites remained. Only in 2011, after launching nearly 140 satellites, did the 24 satellites of the GLONASS global navigation system regain full operational capability.
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.
