What is a "L1 L2 D L5 Gps Jammer"? The Most Authoritative Explanation.
What is a portable GPS jammer?
The portable GPS jammer is particularly powerful and effectively prevents all GPS frequencies (L1, L2, L3, L4 and L5) as well as GSM / UMTS / WiFi signals. The device has a range of up to 20m. This is a WiFi jammer with 12 antennas that can provide strong interference signals.What is the L5 signal?
The L5 operates at 1176.45 MHz, with higher transmission power and enhanced signal architecture compared to other GPS signals (L1 or L2), it is expected that L5 will improve the GPS system’s current performance. The L5 signal is projected to provide a high processing gain due to its large bandwidth and relatively longer spreading codes.What is the difference between L2 and L5?
However, since L2 is newer, its infrastructure is not yet complete. Because of this, it cannot be used on its own: it must be used along with L1 frequencies ( source). L5 is the third GPS signal, operating at 1176 MHz. It is the most advanced GNSS signal yet, but it is still in its infancy, with deployment scheduled for 2021 ( source).How to use L1 and L2 GPS signals?
There are two main ways to make use of the L1 and L2 GPS signals. First, the L1 signal can be used on its own. This will give you about a centimeter of accuracy (when also using RTK) but is still considered slow, taking about 10 minutes to reach that level of accuracy.
