A. 2021 Trajectory data for the Voyager 1 Jupiter egress radio occultation, recovered from NSSDCA Merged Occultation Data. These are probably from a Voyager 1 trajectory reconstructed within 18 months of the encounter. There is almost no documentation accompanying the file in NSSDCA. 2021-11-26 1.0 Initial version of data recovered from NSSDCA and converted to a pair of PDS4 tables. The data have been reformatted into physical records that are commensurate with the original logical records. Records are delimited by carriage-return line-feed pairs. A new PDS4 label has been generated. Table 1, Field 1 claims that there are 824 data records in Table 2. In fact, Table 2 contains only 685 records. The reason for the discrepancy is not known. 1979-03-05T16:07:50Z 1979-03-05T18:21:00Z Calibration Derived Trajectory data for the Voyager 1 Jupiter egress radio occultation. =Voyager Mission urn:nasa:pds:context:investigation:mission.voyager data_to_investigation Voyager Navigation Literature Search Reconstructed spacecraft trajectory during Jupiter encounter using radio tracking and other data.

The first contains one identifying header record; the second contains many data records. Each record is delimited by a Carriage-Return Line-Feed pair. 0 1 This Table has one header record with ten fixed-width fields followed by one Carriage-Return Line-Feed record delimiter.
