Analysis of Integrated Navigation Technology Based on GNSS/UWB

Aiming at the problem that a single positioning system cannot meet the indoor and outdoor high-precision positioning, GNSS/UWB integrated navigation system is proposed. Firstly, this paper introduces the development and research status of the global satellite navigation system; Secondly, The UWB positioning technology in indoor positioning technology is introduced; Finally, the development and research status of GNSS/UWB integrated navigation are introduced. The advantages and disadvantages of the single outdoor or indoor positioning system in the indoor and outdoor integrated navigation system are compared and analyzed. The results show that a single outdoor or indoor positioning system cannot meet the indoor and outdoor high-precision positioning, an effective method of GNSS/UWB fusion positioning is to improve the positioning accuracy and robustness, which can enhance the real-time in time, continuity in space and reliability in accuracy.
