What is GNSS positioning and how accurate can it get?
GNSS stands for Global Navigation Satellite Systems. The most famous constellation is GPS, but nowadays it is possible to receive simultaneously the signal from multiple constellations, such as Glonass, Galileo, and BeiDou. This brings the numbers of satellites visible in the sky close to 100, which results in higher chances of getting a 3D position even in non-open sky conditions. A professional-grade GNSS system is also able to process differential corrections, which are normally broadcasted from a server. This is a real-time computation that results in a corrected position as accurate as a few centimeters.

What is Stepped Frequency Continuous Wave?
Unlike Pulsed-GPR broadcasting a signal centered around one frequency, resulting in a trade-off of resolution and depth for inspecting, stepped frequency continuous wave (SFCW) has the advantage to broadcast an ultra wide-band range of modulated frequencies. The combination of all frequency response enables detection of objects from shallow to deep depth in one scan.
