Copy Citation
The global navigation satellite system (GNSS) positioning for receiver's position is derived through the calculation steps, or algorithm, given below. In essence, a GNSS receiver measures the transmitting time of GNSS signals emitted from four or more GNSS satellites (giving the pseudorange) and these measurements are used to obtain its position (i.e., spatial coordinates) and reception time.

- 3-dimensional distance is given by [math]\displaystyle{ \displaystyle r(\boldsymbol_A,\, \boldsymbol_B) = |\boldsymbol_A - \boldsymbol_B| = \sqrt{(x_A-x_B)^2+(y_A-y_B)^2+(z_A-z_B)^2} }[/math] where [math]\displaystyle{ \displaystyle\boldsymbol_A = (x_A, y_A, z_A) }[/math] and [math]\displaystyle{ \displaystyle\boldsymbol_B = (x_B, y_B, z_B) }[/math] represented in inertial frame.
