7.4 User Science Files Management<br />

7.4.1 Purpose<br />

This procedure describes <strong>the</strong> management of user science files on <strong>the</strong> <strong>South</strong> <strong>Pole</strong> file server.<br />

7.4.2 Participants<br />

a. SPTR Users.<br />

b. WSC.<br />

7.4.3 Procedure<br />

7.4.3.1 General<br />

SPTR users are responsible <strong>for</strong> placing science files on <strong>the</strong> <strong>South</strong> <strong>Pole</strong> file server, acquiring <strong>the</strong><br />

files from <strong>the</strong> White Sands File Server (WSFS) and deleting files from <strong>the</strong> White Sands file server.<br />

Files placed on <strong>the</strong> <strong>South</strong> <strong>Pole</strong> server are serialized and transmitted as a duplicate copy to WSC.<br />

The “original file” remains at <strong>the</strong> <strong>South</strong> <strong>Pole</strong> server in case a retransmission is necessary.<br />

Successfully transmitted files to WSFS are automatically deleted from <strong>the</strong> <strong>South</strong> <strong>Pole</strong> server.<br />

7.4.3.2 Placement of Files on <strong>South</strong> <strong>Pole</strong> File Server<br />

Users may place science files on <strong>the</strong> <strong>South</strong> <strong>Pole</strong> file server <strong>for</strong> KSAR TCP/IP service through<br />

TDRS-1. When placing files on <strong>the</strong> <strong>South</strong> <strong>Pole</strong> file server users must include <strong>the</strong> <strong>South</strong> <strong>Pole</strong><br />

SPTR file server IP address as <strong>the</strong> destination.<br />

7.4.3.3 Acquisition of User Files from WSC File Server<br />

a. Files transmitted from <strong>the</strong> <strong>South</strong> <strong>Pole</strong> to WSC via <strong>the</strong> KSAR TCP/IP service will be<br />

normally transmitted to <strong>the</strong> White Sands file server at WSGT or may be on <strong>the</strong> STGT file<br />

server when TDRS is supported via STGT. Users can <strong>the</strong>n access <strong>the</strong>ir files by FTPing<br />

<strong>the</strong> files from <strong>the</strong> appropriate file server via <strong>the</strong> Internet connection to WSC.<br />

7.4.3.4 Deletion of files from WSC File Server<br />

After <strong>the</strong> successful acquisition of user science files from <strong>the</strong> WSC file server, <strong>the</strong> user is<br />

responsible <strong>for</strong> deleting <strong>the</strong> file from <strong>the</strong> server.<br />
