GC-P2302 is an intrinsically safe UWB positioning base station for mines, based on the DW1000 solution, specifically designed for tunnel/roadway scenarios. Operating in the 3.7-4.2GHz frequency band (avoiding power frequency interference), it achieves 400-meter through-the-earth communication with a 18dBm penetration power. With a sleep current ≤40μA and dimensions of 123×87×19mm (explosion-proof enclosure), it has passed MA/KJ mine safety certification and IECEx Zone 0 explosion-proof certification, addressing core pain points such as signal attenuation and electromagnetic interference in underground personnel/vehicle positioning.
