Abstract⎯The paper considers a complex technology of navigation and geodetic support for airborne geo-
physical surveys by the example of an airborne electromagnetic survey that makes use of an outboard platform
connected to the helicopter with a cable. The technology is based on satellite and photogrammetric methods.
The innovation methods used to determine navigation and geodetic parameters are protected by the Russian
patents and have been tested in practice. The paper presents the results of the authors’ long-term experience
in this field of research.
Airborne geophysical electromagnetic exploration
on the basis of transient electromagnetics, magnetom-
etry and spectrometry is effectively used in engineer-
ing-geophysical and engineering-geological surveys
[1–3]. Such surveys are often conducted with the use
of airborne geophysical outboard platforms with spe-
Similar equipment is produced in foreign countries
by such companies as Fugro N.V., Geotech, U.S.
Geological survey, et al. [1, 2].
Russian airborne geophysical systems such as heli-
complexes with Impulse-Aero
platforms developed at the Siberian Research Institute
of Geology, Geophysics and Mineral Resources
(SNIIGGiMS, Sibgeotech, Aerogeophysical survey in
2001, 2003, 2008) are successfully employed in hydro-
geological search and valuation surveys, engineering
and environmental research, as well as in exploration
activities associated with search for ore and hydrocar-
bon minerals [3–5].
The purpose of this article is to present a complex
technology of navigational and geodetic support,
based on satellite and photogrammetric methods, for
airborne geophysical surveys. Application of the novel
technology is demonstrated with an example of air-
borne electromagnetic (AEM) surveys using an out-
board platform with special-purpose equipment.
ABOUT THE AIRBORNE
The AEM complex Impulse-Aero includes the fol-
lowing basic components: onboard equipment
(installed in a helicopter), an outboard platform, mag-
netometer, and a carrier (helicopter). The platform
and magnetometer are placed under the helicopter
fuselage on a cable with a length of 50–60 m.
The complex can be used for surveys in the
conditions when the crosswind speed does not exceed
5–8 m/s, the temperature range being from –40 to
Navigation and geodetic support plays an import-
ant role in conducting complex airborne geophysical
surveys using such complicated equipment since it
determines, to a large extent, the quality of survey
To provide for navigation and geodetic support of
an AEM complex is a nontrivial task primarily due to
a large number of navigation and geodetic parameters
(Fig. 1) that should comply with the accuracy require-
Table 1 [6, 7] presents the requirements for the
accuracy in determining navigation and geodetic
parameters of AEM survey using an outboard electro-
magnetic (EM) platform. Besides these parameters,
which are of paramount importance for correct pro-
cessing of measurements, some other additional
parameters, such as the platform tilt angle, should also
be taken into consideration [10, 11]. Navigation
