Sec. 1215.106  User command and tracking data.



    (a) User command data may enter the TDRSS via the NASCOM interface 

at one of three locations:

    (1) For Shuttle payloads which utilize the Shuttle commanding 

system, command data must enter the system via the Johnson Space Center 

(JSC)

and is governed by the policies established for STS services (see Sec. 

1215.101).

    (2) For free flyers and other payloads, command data must enter the 

system at the Goddard Space Flight Center (GSFC) if it is to be a 

standard service.

    (3) The use of other command data entry points [e.g., the NASA 

Ground Terminal (NGT) at White Sands, NM, or Johnson Space Center (JSC), 

for payloads using an independent direct link from TDRS to the user 

payload] is considered to be a mission unique service.

    (b) NASA is required to maintain the user satellite orbital elements 

to sufficient accuracy to permit the TDRS system to establish and 

maintain acquisition. This can be accomplished in two ways:

    (1) The user can provide the orbital elements in a NASA format to 

GSFC to meet TDRSS operational requirements.

    (2) The user shall insure that a sufficient quantity of tracking 

data is received at GSFC to permit the determination of the user 

satellite orbital elements. The charges for this service will be 

determined by using the on-orbit service rates.
