Instructions for filling out IGS site logs
1 Dec 2003 (added Height Diff to Ant instructions)
See log form at ftp://igscb.jpl.nasa.gov/pub/station/general/blank.log
General
=======
Please prepare site logs in plain ASCII.
Line length is limited to 80 characters.
See http://igscb.jpl.nasa.gov/network/sitelog-submissions.html for
submission instructions, or email your log to igscb.jpl.nasa.gov if
you prefer. Site logs emailed manually are usually handled by
the CB within about one business day.
Date and time formats are ISO 8061; see http://www.iso.ch/markete/8601.pdf
As a summary, CC=2 digit century
YY=2 digit year
MM=2 digit month
DD=2 digit day of month
T=date/time separator
hh=2 digit hour
mm=2 digit minutes of hour
Z=UTC indicator
/=separator when begin & end times are given
Latitude/Longitude formats are aligned to ISO 6709:
Lat: +/-DDMMSS.SS
Long: +/-DDDMMSS.SS
A + or - sign is required. Leading zeroes must be used as appropriate
to maintain the DDMMSS and DDDMMSS format.
"etc" indicates you may enter any relevant answer, not just a choice
ofthe suggestions shown.
"F7.4," "A4" and so on indicate the FORTRAN-style format which the
response should have.
Example 12345.7 = F7.1
ABCD = A4
Blocks which have a "N.x" definition (namely sections 3-10) should
always have the complete historic set of information; when a change is
made, the previous information is left (for example in section 3.1)
and the new information is placed in a new block numbered 3.2. Please
leave the .x sections uncompleted to remind yourself of the format
when the next change occurs.
Please remove the response hints such as "(F7.4 N/S)" as you fill out
the log (except in the .x sections and Date Removed fields for
currently installed equipment, which you will leave). If an
answer in an optional field is unknown, try to learn the answer for
the next log update.
If you have any questions not answered here, please feel free to
contact the IGS Central Bureau:igscb@igscb.jpl.nasa.gov
Special Instructions by section
================================
0. Form
-----------
If Update:
Previous Site Log : (ssss_CCYYMMDD.log)
If the site already has a log at the IGS Central Bureau, enter
the filename currently found under
ftp://igscb.jpl.nasa.gov/pub/station/log/
ssss = 4 character site name
If Update:
Modified/Added Sections : (n.n,n.n,...)
Enter the sections which have changed from the previous version
of the log. Example: 3.2, 4.2
1. Site Identification of the GNSS Monument
---------------------------------------------
IERS DOMES Number : (A9)
This is strictly required. See
http://lareg.ensg.ign.fr/ITRF/domesreq.html to obtain one.
Monument Description : (PILLAR/BRASS PLATE/STEEL MAST/FICTIVE/etc)
Enter one or more elements as necessary to describe the monument.
Additional Information : (multiple lines)
Suggestions: electrical isolation
2. Site Location Information
-----------------------------
Approximate Position (ITRF)
This should be to a one meter precision. The elevation is to be
given as an F7.1 number representing an ellipsoidal height.
3. GNSS Receiver Information
--------------------------------------
Receiver Type : (A20, from rcvr_ant.tab; see instructions)
Please find your receiver in
ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab and use
the official name, taking care to get capital letters, hyphens,
etc. exactly correct. If you do not find a listing for your
receiver, please notify the IGS Central Bureau
(igscb@igscb.jpl.nasa.gov).
Serial Number : (A20)
Keep the 5 significant characters of the serial number field in
SINEX in mind: do not enter "S/N 12345" instead of "12345" since
valuable information will be lost.
Firmware Version : (A11)
Keep the 11 significant characters of the field in SINEX in mind.
Elevation Cutoff Setting : (deg)
Please respond with the tracking cutoff as set in the receiver,
regardless of terrain or obstructions in the area.
Temperature Stabiliz. : (none or tolerance in degrees C.)
This refers to the temperature of the room in which the receiver
is housed.
Date Removed : (CCYY-MM-DDThh:mmZ)
In the block for the receiver currently in operation, leave this
line as is to remind yourselt of the format when the next receiver
change is made.
4. GNSS Antenna Information
---------------------------------------
Antenna Type : (A20 from rcvr_ant.tab; see instructions)
Please find your antenna in
ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab and
use the official name, taking care to get capital letters, hyphens,
etc. exactly correct. If you do not find a listing for your
antenna, please notify the IGS Central Bureau
(igscb@igscb.jpl.nasa.gov). Please do not use antenna names from a
"Previously valid" section. Choose the corresponding new antenna
name. You may indicate a Radome code from rcvr_ant.tab in columns
17-20 of the Antenna Type if desired.
Serial Number : (A20)
Keep the 5 significant characters of the serial number field in
SINEX in mind: do not enter "S/N 12345" instead of "12345" since
valuable information will be lost.
Antenna Reference Point : (BPA/BCR/XXX from "antenna.gra"; see instructions)
Locate your antenna in the file
ftp://igscb.jpl.nasa.gov/pub/station/general/antenna.gra
Indicate the three-letter abbreviation for the point which is
indicated equivalent to ARP for your antenna. Contact the Central
Bureau (igscb@igscb.jpl.nasa.gov) if your antenna does not appear.
Marker->ARP Up Ecc. (m) : (F8.4)
This is the antenna height measured to an accuracy of 1mm
and defined as the vertical distance of the ARP from the marker
described in section 1.
Alignment from True N : (deg; + is clockwise/east)
The positive direction is clockwise, so that due east
would be equivalent to a response of "+90"
Antenna Radome Type : (A4 from rcvr_ant.tab; see instructions)
Place a Radome code from
ftp://igscb.jpl.nasa.gov/pub/station/general/rcvr_ant.tab here.
"NONE" indicates there is no radome.
Date Removed : (CCYY-MM-DDThh:mmZ)
In the block for the antenna currently in operation, leave this
line as is to remind yourselt of the format when the next antenna
change is made.
8. Meterological Information
-------------------------------------------------------------
Height Diff to Ant : (m)
This is sensor height minus antenna height. In other words, positive
if the sensor is above the antenna. Please note that this convention
was used in the Notes.
12. Responsible Agency (if different from 9.)
-------------------------------------------------------------
The primary contacts listed here should always be the first choice for
questions about operation of the site. This person will receive
automated emails regarding site log or RINEX errors and should be
someone who can answer questions about the configuration and data
delivery for this site.
13. More Information
-------------------------------------------------------------
Primary Data Center :
Secondary Data Center :
Please list the DC where the station's data ordinarily goes first as
"Primary." Use "Secondary" either for a second location where
the station's data always goes, or would go in the case of a
failure with the Primary DC.
Additional Information:
Anything you feel is important. Some possibilities to consider are:
