name: WLS
full_form: Weighted Least Square
context: In the case that the UE reports measurements for more than a single GNSS, the pseudo-ranges are corrected for the time offsets between the GNSSs relative to the selected reference time using the GNSS-GNSS time offsets available at the SS: , where is the measured pseudo-range of satellite i of GNSSm. The system time of GNSSk is the reference time frame, andis the available GNSS-GNSS time offset, and c is the speed of light. Step 3: Formation of weighting matrix The UE reported "codePhaseRMSError" values are used to calculate the weighting matrix for the WLS algorithm [7]. According to TS 36.355 [3], the encoding for this field is a 6 bit value that consists of a 3 bit mantissa, Xi and a 3 bit exponent, Yi for each SVi: The weighting Matrix W is defined as a diagonal matrix containing the estimated variances calculated from the "codePhaseRMSError" values: Step 4: WLS position solution The WLS position solution is described in reference [7] and usually requires the following steps: 1)
description: Weighted Least Square (WLS) is a mathematical method used to calculate precise positions in Global Navigation Satellite Systems (GNSS). It works by considering pseudo-ranges from satellites and their associated errors, assigning weights to each measurement based on its accuracy. This weighted sum of measurements is then used to determine the most accurate position.
explanation: WLS is classified as a positioning technique because its primary function is to determine location using GNSS data. It leverages mathematical algorithms to process satellite signals and calculate precise coordinates.
