Abstract:	The Monterey Bay Precise Positioning Experiment was a test of the accuracy of GPS receivers under ship dynamic conditions. Four pairs of receivers, Ashtech, Magnavox, Tl and Trimble were used, one on a ship and the other on a nearby shore site. The ship was tracked by a PolarFix laser system. This laser tracker, along with the angles from two gyros, gave the trajectory of the mobile antenna at the 60 cm level. The test took place over 4 days during the week of December 4-7, 1990. No SA was in effect during the test. This paper will address the accuracy of the real time solutions produced by the Ashtech, Magnavox, and Trimble receivers. In addition the simple method of adjusting the mobile receiver solution by the error in the fixed receiver will be addressed. This technique produced horizontal position errors of 2.5 m rms and with a vertical error component only slightly higher at 3.3 m rms.
