TDOA Positioning with Chan's Algorithm: Implementation and Applications
TDOA Positioning using Chan's Algorithm - A comprehensive implementation guide featuring multiple Weighted Least Squares (WLS) computations for scenarios where mobile stations are relatively close to base stations. Input parameters include R(N-1×1): TDOA measurement values and Pbs(N×2): Base station coordinates (X in first column, Y in second column) with reference base station coordinates in the first row. Output parameters comprise POS_ref(2×1): Initial WLS estimation result serving as reference for final positioning decision, along with multiple positioning solutions POS1(2×1), POS2(2×1), POS3(2×1), and POS4(2×1).
