Excellent sample demonstration!
------------------------------
Precise Positioning Service is for the DOD only. Only Standard Positioning
Service (SPS) is available to the public. With SPS, 100 meter accuracy
is observed 95% of the time. The following plot shows SPS information
gathered at USNA over a 6 hour period. Notice the brief 4 minute excursion
over 1/2 mile at 14 knots for our fixed building!
