The Astrogeodynamical Observatory in Borowiec
 The
Astrogeodynamical
Observatory in Borowiec
The Observatory is involved in the following projects:
- laser tracking of satellites, - positioning measurements
with the use of GPS technology in global geodynamic
programs, - satellite synchronisation of time and development
of measurement technologies, - comparison of atomic
clocks at large distances with the use of GPS technology
and laser range finder.
Observation Programs
The Satellite Laser Ranging station at Borowiec
(7711) in the framework of the International Laser Ranging
Service (ILRS) performed in 2001 708 laser observations
of 16 SLR satellites: - LAGEOS satellites - 249, - ERS-2
satellite (ESA program): - 75, - other low satellites
- 364, - high satellites (GLONASS, ETALON): - 20.
The results of the observations were used within the
framework of programs of international organizations,
institutions, agencies and consortia, among others by
ESA, EUROLAS, NASA.
 The
accuracy of these results was on the level of 18 mm,
precision 6 mm. The most imporant upgrading of the Borowiec
SLR system in 2001 was introduction of the time and
frequency from a new cesium frequency standard HP5071A.
The orbital analysis of the SLR results by orbital programm
NASA GEODYN-II was continued in 2001 at Borowiec Observatory.
In the frame of this task the Borowiec SLR station coordinates
in the period 1993.5 - 2000.5 were determined. The coordinates
stability was equal 17 mm in the whole period. The coordinates
stability for the all SLR stations in 1999 and 2000
has also been determined. (S. Schillak)
 The
permanent GPS station located at Borowiec and known
as BOR1 has been integrated with EUREF network since
1996. The EUREF Permanent GPS network was established
to maintain the European Reference Frame. BOR1 station
delivers high quality and oustanding international reputation
data. BOR1 maks a valuable contribution to global geodesy
and related research in the frame of IGS (International
GPS Service). The data delivered by BOR1 are used for
precise GPS orbit calculation by: GeoForschung Zentrum
Potsdam, Germany, Natural Resources Canada, Center for
Orbit Determination Europa, 
Switzerland and Scripps Institution of Oceanography,
USA. This demonstrates the utility of the BOR1 site
to users. M. Lehman
The SRC Astrogeodynamical Observatory as the third station
in the world initiated measurements of signals from
GLONASS satellites with the use of a multichannel receiver.
The measurements make it possible to verify atomic clocks
with accuracy better than 1 ns and to perform geodetic
observations similar to with the GPS system. The Borowiec
station is the only station in Poland that carries out
geodetic observations using three systems: laser, GPS
and Glonass. The station participated in the first IGEX
compaign (International GLONASS Experiment), managed
by IGS (International GPS Service for Geodynamics),
where all three systems were used. J. Nawrocki
