Installation-Test Checklist; Checking The Network - NorthStar 972 Installation Manual

SECTION FIVE: Checking out the system
Although the U.S. government identifies WAAS satellites by their pseudo random number (PRN)—a
three-digit number ranging from 120 to 138—the 972 identifies them by two-digit numbers ranging
from 33 to 51. For example, the satellite for the Atlantic Operating Region (AOR) is PRN 122, which
the 972 displays as 35. See Table 8 below for the identification numbers for WAAS satellites that may
be displayed on the screen.
