Equation 1Q: How does measurement differencing affect my computed position?
A: The short answer is, “That depends.”
Standalone, or undifferenced, measurements obviously produce the poorest positioning performance. However, how we proceed from this most basic data processing approach may affect the computed solution. In this article, we look at the details of why this occurs.
