The following types of magnetic observations
and surveys were made by the
geophysicists of the former USSR on its
territory and on the territories of other
countries and aquatories:
. observations from the observatories
S observations from the 1 76 repeat
stations . land magnetic surveys . airborne surveys . hydromagnetic surveys . surveys from satellites . the standard magnetic measurements
carried out at the observatories with
standard apparatus by a standard
program
At the repeat stations, the modulus of
total force (F), the horizontal component
(H) and the magnetic declination (D) are
measured with proton magnetometer
(MMP-203), the quartz QHM-magnetometer
and the astronomical theodolite.
The errors of the measurement of F, H and
D are equal to 12nT, 35nT, *12'
accordingly. The observations are execute
once in five years.
