Many of our customers ask us why our solution requires three GNSS antennas. This is necessary to ensure the detection of all possible types of attacks:
- Non-coherent or asynchronous
- Coherent or synchronous
- Coherent with multiple transmitters
In this video, you will find an animation explaining the fundamental differences between attack types:
Here, you will find out how the GNSS receiver behaves under synchronous and asynchronous attack:
Why should you consider an advanced attack scenario?
- It is false that a coherent attack is complicated and expensive.
- A coherent attack does not require a lot of power. It can be conducted with any SDR from a distance of tens of kilometers.
- A time server under a coherent attack will not display errors or even warnings. You will just have an incorrect time.
