Paper Title:
Precise Location Technology Based on Chirp Spread Spectrum
  Abstract

This article introduces chirp spread spectrum technology (CSS for short), and location algorithm is optimized. Symmetric double-sided two way ranging technique (SDS–TWR for short) is applied to improve measurement accuracy and range. Linear frequency modulation ranging technology uses protocols combining CSMA / CA and TDMA, and adjusts dynamically transmission rate and frame length according to noise, interference and multipath to ensure optimal throughput and accurate distance information. System has anti-jamming capability and covers great distance.
