All CGSIC:
With my apologies, I unintentionally sent out misinformation regarding NANU 2012003 on SVN-49. The correct information is as follows:
In an effort to improve constellation sustainment, on or about 01FEB2012, SVN-49 will resume transmitting an L-band signal using PRN-24 as a test asset. Upon completion of the test event, SVN-49 will once again be decommissioned from active service. PRN-24 will then once again be available for future satellite service.
NANU2012003 text is provided below for your reference. Contact me directly by email with your comments or concerns.
