Data - FTP Server Layout

Please note! By downloading files from UNAVCO's ftp server you are agreeing to abide by the UNAVCO Data Policy.

The following describes our FTP server layout, subject to the hierarchy:

L1-only supersedes sub-hourly ( = nrt) supersedes highrate supersedes multi-hourly or hourly or daily

e.g. L1-only data that is also highrate and sub-hourly would only be in our L1 directory. Regularly incoming sub-daily data is also combined into daily data, usually as RINEX.

For RINEX files created at UNAVCO, the standard observables are L1, L2, C1, P1, P2, S1, and S2 (if available in the raw data). For customized RINEX with other observables (e.g. doppler D1 and D2), please contact us.

/L1/rinex/yyyy/ddd

L1-only data as RINEX:

Hatanaka UNIX-compress RINEX observation files for year yyyy and day ddd;
UNIX-compress RINEX observation files for year yyyy and day ddd;
teqc qc report files for year yyyy and day ddd

<4-char ID><ddd>0.<yy>d.Z	Hatanaka UNIX-compress RINEX observation file
<4-char ID><ddd>0.<yy>o.Z	UNIX-compress RINEX observation file
<4-char ID><ddd>0.<yy>n.Z	UNIX-compress RINEX navigation file (if available)
<4-char ID><ddd>0.<yy>S	teqc qc report file

Note: L1 UNIX-compress RINEX observation files are currently kept for 1 year.

/LEO	(intermittent) TRBC files for JPL customers during GGN failover mode

/dai	pickup area for archive's Data Archive Interface

/highrate

data where sample interval ≤ 1 second:

         /raw/yyyy/ddd/site
