TDRS F5 will be removed from service at midnight UTC on December 8, 2014. At that time, all South Pole science
transmissions will be switched to TDRS F6. TDRS F6 is visible during the same window as the GOES satellite,
and passes will overlap on the schedule.

The South Pole weekly satellite schedule now includes pass data for the NATO IVB satellite.
March 10, 2014
A number of new Space Network users will be competing with SPTR for time on TDRS F5 and F6 for approximately the
next 3 months. This may result in lower aggregate pass times. Pass time within the SPTR viewing window is
continuously monitored and time will be added as it becomes available, up to a daily limit of 4 hours.
March 1, 2013
Effective March 11, 2013, F6 will replace F3 as TDRS-Spare. SPTR availability should not be affected by this change.
March 22, 2012
According to a Network Advisory Message issued today (NAM 0001555), northbound K-band services will no longer be
available on TDRS F3-SA1 effective April 9, 2012. This will restrict SPTR usage of F3 to antenna SA2 and may reduce
overall time available.
March 5, 2012
Effective January 23 2012, TDRS F6 is no longer available for use by the Space Network. SPTR will continue to utilize
TDRS F5 as a primary resource and TDRS F3 as a backup resource to clear science data backlogs.
