Resumen:
We report about CCD (Charge Coupled Device) experiments with the isntruments of
astrometry and geodesy for the longitude and latitude determinations. At the
Techn. University Vienna (TU Vienna), a mobile zenith camera "G1" was developed,
based on CCD MX916 (Starlight Xpress) and F=20 cm photo optic. With
Hipparcos/Tycho Catalogue, the first results show accuracy up to 0."5 for
latitude/longitude. The PC-guided observations can be completed within 10
minutes. The camera G1 (near 4 kg) is used for astrogeodesy (geoid, Earth's
crust, etc.). At the Belgrade Astronomical Observatory (AOB), the accuracy of
(mean value of) latitude/longitude determinations can be a few 0."01 using
zenith stars, Tycho-2 Catalogue and a ST-8 of SBIG (Santa Barbara Instrument
Group) with zenith-telescope BLZ (D=11 cm, F=128.7 cm). The same equipment with
PIP instrument (D=20 cm and F=457.7 cm, Punta Indio PZT, near La Plata) yields a
little better accuracy than the BLZ's one. Both instruments, BLZ and PIP, where
in the list of Bureau International de l'Heure - BIH. The mentioned instruments
have acquired good possibilities for semi or full-automatic observations
