For first installation you need
ftp://lacerta.gsfc.nasa.gov/SOLVE/first_save.zip file.
Refer to the general
installation instruction and
specific instructions for
HP-UX or
Linux operating systems.
Calc/Solve runs only under Linux, and HP-UX operating systems
on processors i386, x86_64 and PA-RISC architectures.

List of a priori files.
Calc/Solve requires a priori files. You can find below links to the versions
of these files maintained by VLBI team of the Goddard Space Flight Center.
- blokq.dat -- file with
a priori station positions, source positions, catalogue of ocean
loading coefficients.
- ut1pm.dat -- file with
a priori polar motion and UT1 in binary Calc format. Updated daily
around 04:30 local time.
- usno_finals.erp --
file with a priori polar motion and UT1 in erp format. Updated daily
around 04:30 local time.
- ut1ls.dat -- file with
leap second: value of function UT1-TAI for different epochs.
- DE405_be.jpl -- ephemerides
file for planets and Moon. Big endian version.
- DE405_le.jpl -- ephemerides
file for planets and Moon. Little endian version.
- ECCDAT.ecc -- station's
eccentricity file.
- antenna.dat -- file with
station's characteristics. (NB: obsolete)
- concrete.dat -- EOP mod-file
for pre-1984 data (NB: poor quality).
- sitpl.dat -- file with
station names and names of tectonic plates to which the station
belongs.
- last.erp -- mod-file
produced by Goddard EOP Kalman filter using all 24 hour VLBI
observations. This file is updated with processing each new session.
- glo.src -- mod-file with
coordinates of all sources.
- glo.sit -- mod-file with
positions of all stations.
- glo.vel -- mod-file with
velocities of all stations.
- 2007c.axo -- antenna axis
offsets for all stations.
- source.names -- the table
of correspondence between the IVS source names, IAU B1950 names
(the same as IERS names), IAU J2000 names, IERS designators.
- blokq_dat.hps -- mod-file
in HARPOS format of the site position variations caused by ocean
loading. This file was obtained by converting the amplitudes and
phases of the ocean loading taken from the blokq.dat file,
revision of 2002.12.15 . NB: this file is provided for
backward compatibility only.
- Table of coefficients of the amplitudes of the 3-D displacements
caused by ocean loading for all VLBI sites.
- Times series of the 3-D displacements caused by
atmosphere pressure loading for all VLBI sites.
Lists of sessions with problems.
- List of 245 databases with wrong
order of observations. Calc/Solve is unable to process them and
issues an error message like
IUER=8320 LOOP "Wrong order of observations detected in the session
$88AUG31X <14> : 686-th observation occurred BEFORE the previous one at
6.000002 sec. Database file should be cured!!!"
Such databases should be cured. Corrected versions of the databases
are available on-line in
Goddard Space Flight Center and off-line
in Geodetic
Institute of the University of Bonn.
- List of 9 databases with
mixed baselines. It means that the database contains both
baselines AB and BA. Advanced programs of Calc/Solve such as
GAMB, PAMB, ELIM are unable to process such sessions.
- List of the databases with
huge clock offsets. Imposing a priori clock model is strongly
recommended in data analysis of these sessions.
- List of the databases with
huge clock rates. Imposing a priori clock model is strongly
recommended in data analysis of these sessions.
- List of signs of applied cable
calibrations for (almnost) all databases and stations.
- List of clock breaks
from the gsf2007c solution.
