Types of Signal blocker Jamming
In the overlapping coverage area of two or more base stations, the field strength at the receiving point is the sum of the signal field strengths from each base station. Due to the different paths, media and transmitting equipment used for the signal propagation of each base station, the time for the signals sent by each base station to reach the overlapping area is also different, that is, there is a relative time delay difference between the signals, resulting in the relative phase of each signal. Difference.
Interference occurs when an inherently low-power signal is overwhelmed by other radio signals on the same frequency. This can happen when the receiver is in close proximity to other electronic equipment, radio antennas or modems. Jamming signal could be unintentionally caused by amateur radio operators sending out radio signals in the area. Interference can reduce positioning accuracy, or cause the receiver to lose RTK or even PVT at the same time.
