Signal blocker Jamming Detector

Interference occurs when an inherently low-power GNSS signal is overwhelmed by other signal jammer electrical signals at the same frequency. This can happen when the GNSS receiver is in close proximity to other electronic devices, radio antennas or modems. Radio amateurs sending out radio signals in the area may inadvertently cause GNSS interference. Interference can reduce positioning accuracy, or cause the receiver to lose RTK or even PVT (position, velocity, time) at the same time.

Electronic equipment may introduce narrowband interference affecting parts of the GNSS spectrum. To mitigate the effects of narrowband interference, the three notch filters can be configured in automatic or manual mode. These notch filters effectively remove narrow-band portions of the RF spectrum that belong to the vicinity of interfering signals. In the L2 band, which is open for use by radio amateurs, receivers are particularly vulnerable to this type of interference.Interference occurs when inherently low-power GNSS signals are overwhelmed by other radio signals on the same frequency.
