Notes
1. NASA Catalog Number is also known as NORAD or U.S. Space Command object
number.
2. No orbital plane position = satellite no longer operational.
3. Clock: Rb = Rubidium; Cs = Cesium
4. PRN 3 is operating on Rb clock without temperature control.
5. The power supplies of PRN 11 and 13 have insufficient capacity to maintain
L1/L2 transmissions during eclipse season. During this period, the L1/L2
transmissions of PRN 11 and 13 may be turned off for up to 12 hours a day.
6. PRN number of SVN 32 was changed from 32 to 1 on 93-01-28.
