Initial guess: ( (x_0, y_0, z_0) = (0,0,0) ) Step 2: Receive pseudoranges from 4 satellites (units after linearization in meters) Step 3: Form the design matrix ( H ) (each row = unit vector from guess to satellite i, plus a 1 for clock term)

: Satellites orbit at approximately 20,000 km, transmitting signals that include their exact location and the time the signal was sent. Initial guess: ( (x_0, y_0, z_0) = (0,0,0)

Geodesy is the science of measuring Earth's shape and size. In practice, we often have more satellite measurements than we strictly need (e.g., seeing 8 satellites instead of 4). Least Squares Initial guess: ( (x_0
