Geodetic measurements with Rogue Global Positioning System (GPS) receivers from sites in the California Permanent GPS Geodetic Array (PGGA) have been analyzed using the GIPSY orbit-determination and baseline-estimation software. Based on an unbiased selection of 23 daily measurements spanning 8 months, the low-frequency ({approx gt} weeks) contributions to the long-term repeatabilities of baseline measurements are approximately 5, 3, and 8 mm for the east, north, and vertical components. Short-term contributions to the long-term repeatabilities were evaluated by examining data from the week of October 21, 1990, which showed the lowest short-term scatter. For this week, daily repeatabilities of 2-3 mm in the horizontal and 4 mm in the vertical have been achieved for the 172-km JPL-Pinyon baseline, consistent with carrier phase data noise of {approximately}6 mm. High quality ({approx lt}5 mm) repeatabilities have been achieved for all components of the other baselines as well.
