X-Ray Timing Explorer

NSSDCA ID: 1995-074A

Telecommunications Description

1. Requires continuous TDRSS MA return link coverage except for zone of exclusion: - Real time and playback of engineering/housekeeping data at 16 or 32 kbs - Playback of science dta at 48 or 64 kbs

2. Requires 20 minutes of SSA contacts with alternating TDRSS per orbit: - Real time and playback of engineering/housekeeping data at 32 kbs - Playback of science data at 512 or 1024 kbs

3. For launch and contigency, requires TDRSS MA/SSA real time engineering and housekeeping at 1 kbs.

4. The bit error rate shall be less than 1 in 10E8 for at least 95% of the orbits.
