Table 1[1] presents an order of magnitude of the 3-D position/time errors achieved with different types of receivers, both for Standard Positioning Service (SPS) and Precise Positioning Service (PPS) using legacy GPS. Note that this table is valid for GPS only and it is provided here for illustrative purposes[2].
