JPL MMNAV to VLBA and Canadian Correlators
What: The reconstructed orbits will be based
on S- range and S- and Ku-band range-rate data.
The VLBA and Canadian correlators will retrieve the reconstructed
orbit from the JPL MMNAV team via the DOTS.
How: The JPL MMNAV team will supply files in SPICE SPK format named YYMMDD-YYMMDD-r.bsp[.v].gz where the first YYMMDD group is the start date and the second YYMMDD group is the stop date (UTC days). The `-r.bsp' indicates a reconstructed binary SPICE format. The `.gz' extension indicates the file is `gzip'-ed.
When: Each orbit will cover a period of 7 days (to the end of that tracking pass, i.e. no tracking pass will be segmented), and will be made available within 2 weeks of the observation. New files will generally be made available once per week by the end of day Friday (PST).
Where: DSN orbits will be available in pub/vsop/oddata/rec on the DOTS FTP site.
