Subject: Detailed Description of Full-Rate Data Delivery

Dear colleagues,

at the ILRS meetings in Nice during the EGS General Assembly in Spring 2002 it
was decided to archive the full-rate data again. This was announced at the ILRS
13th International Laser Ranging Workshop in Washington, October 07-11, 2002.
Herewith the details of full-rate data delivery and file naming convention are
given:

1. Full-rate data delivery

Each ILRS SLR station sends a daily file for each satellite to the corresponding
Global Data Centers (EDC or HTSI/CDDIS), containing all passes starting the same day.

The full-rate data should be sent via ftp to the following incoming directories at
HTSI/CDDIS and EDC respectively:

HTSI: [fg_normpts.fullrate] (same path as for normal points, but other directory)
EDC : incoming/laser/frdata/

The Global ILRS Data Centers will generate monthly files of the daily files.

The daily and monthly full-rate data files will be available at CDDIS and EDC
respectively:

CDDIS: /slr/slrfr/sname/yyyy/ (monthly files)
/slr/slrfr/sname/yyyy/daily (daily files)
EDC : pub/laser/frdata/daily/ (daily files
pub/laser/frdata/monthly/ (monthly files)


2. File name convention

´statno´_´yy´´mm´´dd´_´r´.´satnam´´.Z´

with ´statno´ : CDP station number
´yy´ : two-digit year
´mm´ : month
´dd´ : day
´r´ : relase flag (´a´ = first release, ´b´ = second release, etc.)
´satnam´ : satellite name from the list below

The file has to be UNIX-compressed (extension ´.Z´). For DOS executables of
the UNIX compression see e.g.:
ftp://igscb.jpl.nasa.gov/igscb/software/compress/dos

The approved satellite names are (lowercase, no dashes or other special characters):

ajisai
adeos2
beaconc
champ
ers2
envisat
etalon1
etalon2
gfo1
glonass84
glonass86
glonass87
gracea
graceb
icesat
jason1
lre
lageos1
lageos2
meteor3m
reflector
starlette
starshine3
stella
topex

(See also http://ilrs.gsfc.nasa.gov/products_formats_procedures/fullrate/index.html):

Example:

Station Herstmonceux, satellite LAGEOS-1, all passes starting on Nov. 20, 2002, first release:

7840_021120_a.lageos1.Z


3. Calibration data

It was decided not to archive the calibration data. If they are needed, the
corresponding SLR station should be contacted.

IMPLEMENTATION DATE: March 01, 2003


Best regards,

Wolfgang Seemueller
Carey Noll
