VG1 from Titan: VG1-SSA-RSS-1-ROCC-V1.0
VG1-SSA-RSS-1-ROCC-V1.0	PDS 3 CERTIFIED

Start Time: 1980-11-12 14:35:00 - Stop Time: 1980-11-13 07:29:59

This volume contains raw data collected during the Titan radio occultation of Voyager 1 in November 1980 plus ancillary files that might be useful in analysis of those data from the VG1-SSA-RSS-1-ROCC-V1.0 data set.

The Data Table contains the state vectors for each body with respect to the spacecraft. The first six columns give the date and time of the vector set; the seventh column contains repeating 6-element vectors for each body. The first 3 elements give xyz position of Body 1 with respect to the spacecraft, the second 3 elements give its velocity, the third 3 elements give the xyz position of Body 2, etc. Data are represented as 80-byte card images, followed by ASCII carriage-return line-feed pairs. Except for those, there are no delimiters between columns or items.

This file contains binary data describing pointing of the spacecraft high-gain antenna during the Voyager 1 encounter with Titan. The file has 18 fields per record, with records 656 bits long. The first 17 fields are 36 bit, one's complement integers, and the final field is 44 bits. The first number is S/C event time in seconds from 1950. An offset of 9.200000512e+8 seconds must be added to the stored value to obtain the correct time. The next 16 fields have all been scaled by 10^8, so the integer must be divided by 10^8 to obtain the correct value. The final field is a 44 bit, fixed point one's complement number. There are 36 bits to the left of the decimal and 8 to the right of the decimal. This number also has a scaling factor of 10^8. The fields are as follows: 1) SC event time 2) Angle between HGA Boresite and virtual image 3) Angle between Earth and virtual image 4) Angle between planet and virtual image 5) Angle between HGA Boresite and Earth 6) Angle between planet and Earth 7) Virtual image x-component 8) Virtual image y-component 9) Virtual image z-component 10) HGA Boresite pointing vector x-component 11) HGA Boresite pointing vector y-component 12) HGA Boresite pointing vector z-component 13) Earth x-component 14) Earth y-component 15) Earth z-component 16) Target body x-component 17) Target body y-component 18) Target body z-component
