EDR Header Description
BYTE BITS NAME TYPE DESCRIPTION
------------------------------------------------------------------------------
0 16 "REC_NUM" LSB INT The first 2 bytes contain the record
number which is always zero.
2 80 "PROJ_NAME" CHAR "GALILEO "
12 48 "INST_NAME" CHAR "PWS "
18 32 "FIRST RIM" LSB INT First spacecraft clock. RIM = spacecraft
clock for the first record in the file
with valid data. One RIM is 60 2/3
seconds. The structure of the spacecraft
clock (SCLK) is RIM.MF.R.S, where MF is
the minor frame, R is the real time
interrupt (RTI = 0-9) and S is the
sub-RTI (0-7).
22 8 "FIRST MF" INT MOD91 = the minor frame of the current
RIM (spacecraft clock). Each MOD91
is approximately 2/3 seconds.
23 8 "FIRST RTI" INT MOD10 = real time interrupt of current
minor frame. There are 10 RTI per MF.
24 8 "FIRST MOD8" INT MOD8 = sub-real time interrupt of the
current RTI frame. There are 8 per RTI.
25 32 "LAST RIM" LSB INT Last spacecraft clock. RIM = spacecraft
clock for the last record in the file
with valid data. One RIM is 60 2/3
seconds. The structure of the spacecraft
clock (SCLK) is RIM.MF.R.S, where MF is
the minor frame, R is the real time
interrupt (RTI = 0-9) and S is the
sub-RTI (0-7).
29 8 "LAST MF" INT MOD91 = the minor frame of the current
RIM (spacecraft clock). Each MOD91
is approximately 2/3 seconds.
30 8 "LAST RTI" INT MOD10 = real time interrupt of current
minor frame. There are 10 RTI per MF.
31 8 "LAST MOD8" INT MOD8 = sub-real time interrupt of the
current RTI frame. There are 8 per RTI.
32 16 "1st YEAR" LSB INT YEAR of the spacecraft event time (SCET)
of the first data record.
34 16 "1st DAY" LSB INT DAY of the year of the SCET of the
first data record.
36 8 "1st HOUR" INT Hour of the day of the SCET of the
first data record.
37 8 "1st MIN" INT Minute of the hour of the SCET of
the first data record.
38 8 "1st SEC" INT Second of the minute of the SCET of
the first data record.
39 16 "1st MSEC" LSB INT Millisecond of the second of the SCET
of the first data record.
41 16 "LAST YEAR" LSB INT YEAR of the SCET of the last data record.
43 16 "LAST DAY" LSB INT DAY of the year of the SCET of the
last data record.
45 8 "LAST HOUR" INT Hour of the day of the SCET of the
last data record.
46 8 "LAST MIN" INT Minute of the hour of the SCET of
the last data record.
47 8 "LAST SEC" INT Second of the minute of the SCET of
the last data record.
48 16 "LAST MSEC" LSB INT Millisecond of the second of the SCET
of the last data record.
50 8 "TOT REC" INT Total number of records in this file
including all header records.
51 8 "MAX AGC" INT Maximum automatic gain control in the
AGC field of EDR records.
52 8 "MIN AGC" INT Minimum automatic gain control in the
AGC field of EDR records.
53 0-1 "SOURCE" BIT Input source 0 = realtime or
1 = asynchronous playback.
53 2-6 "RESERVED" N/A Reserved bits
54 96 "VALID" BIT Bit map corresponding to data for each
MOD91 count indicating if it is present.
1 = present 0 = not present
least significant bit of byte 54
corresponds to first record.
66 8 "TEL FMT" INT Realtime identifier of format
identification (FID) in low rate science
(LRS) header. For asynchronous playback
(APB) data this field contains the record
identifier.
12 = MPW 16 = HPW
14 = MPP 19 = LPW
67 8 "INST MODE" INT Waveform receiver mode:
0 = waveform survey
1 = 100.8 kbps (10 kHz)
2 = 806.4 kbps (80 kHz)
3 = 12.6 kbps ( 1 kHz)
68 16 "VERSION" LSB INT Catalog version for identical frames.
Used by MIPS processing.
70 8 "PARTITION" INT SCLK partition number in case of a
clock rollover.
71 32 "PKT TYPE" CHAR SFDU packet type.
75 16 "1st ERT YR" LSB INT YEAR of the earth receive time (ERT) of
the first data record.
77 16 "1st ERT DAY" LSB INT DAY of the year of the ERT of the
first data record.
79 8 "1st ERT HR" INT Hour of the day of the ERT of the
first data record.
80 8 "1st ERT MN" INT Minute of the hour of the ERT of
the first data record.

the last data record.
86 16 "Lst ERT DAY" LSB INT DAY of the year of the ERT of the
last data record.
88 8 "Lst ERT HR" INT Hour of the day of the ERT of the
last data record.
