Abstract: Based on chirp spread spectrum ultra-wideband technology, system adopts Symmetric Double-Sided Two Way Ranging technique(SDS-TWR for short) to reduce noise, interference and multi-path inference and improve accuracy of ranging and location. The location algorithm is optimized. The problem of beyond visual range caused by the fluctuation and bending in horizontal and vertical field is solved in mining face. System has anti-jamming capability and covers great distance.

Key words: chirp spread spectrum, ultra-wideband, symmetric double-sided two way ranging
