GALILEO PWS GANYMEDE 1 OBSERVATION PLANNING


What's new (16 April 1996)

An overview of the planning for G1 encounter period with the associated geometry. For most uses, this plot is too compressed in time to allow any detailed information to be gleaned, however, it does show the RTS downlink format as a function of time in the red hatched region at the bottom and also indicators of when buffer dumps to tape occur. Some detailed versions of this plot are provided below for specific PWS observations.

And 1-day summaries for greater detail:

Magnetospheric Survey, R > 50 Rj

This includes the period from 1996, Day 229 (16 August)/16:00 - Day 246 (2 September)/13:00. The rest of the orbit is not covered by Realtime Science due to downlink limitations.

Spectrum Analyzer Mode:

Wideband Mode: (This is mostly irrelevant since little or no wideband data will be obtained in the Magnetospheric Survey--only occasional fill data)


Magnetospheric Survey, R < 50 Rj

This includes the period from 1996, Day 182 (30 June)/14:00 - Day 192 (10 July)/05:30.

Spectrum Analyzer Mode:

Wideband Mode: (This is mostly irrelevant since little or no wideband data will be obtained in the Survey--only occasional fill data and data which is automatically recorded with remote sensing recorded observations)


Plasma Sheet Crossing

Record LPW for ~45 minutes beginning at about 02:00 on day 182 at a distance of ~ 27.4 Rj. Here is the geometry for this observation.

Spectrum Analyzer Mode:

Wideband Mode:

Playback Strategy:

Return LPW (Golay) wideband data at rate of 2:1 by returning every other waveform snapshot.


Ganymede Closest Approach

Record LPW for ~45 minutes beginning at about 06:07 on day 179. Here is the geometry for this wake passage.

Spectrum Analyzer Mode:

Wideband Mode:

Playback Strategy:

Return LPW (Golay) wideband data at a rate of 2:1 by sending back every other waveform snapshot
