Container facility on western pier face. Presenter’s Name June 17, 2003 Findings of Feb 2003 ANT PR articulated with certainty that the Isabela site does not provide a constant and reliable signal to the U.S. Virgin Islands (St. Thomas and St. Croix) During the performance of the ANT’s (Aids to Navigation Team) primary mission, they have experienced the loss of the DGPS signal for hours and on some occasion even days. During these periods where the signal became indiscernible and unusable, the ANT team could not and did not position ATON After signal verifications, we found the signal to be less than 34 micro volts in some of the South East regions of Puerto Rico, and St Thomas. (75 micro volts per meter). We recommended a site at Naval Station Roosevelt Roads PR.
