DEVELOPING A PROCEDURE FOR RADIOSOUNDING OF THE SATELLITE COVERAGE AREA
using a Network of Ground Receivers (Ten-Mayak)
Research Area: Educational Demonstrations
Expedition(s): 4, 5, 7, 8, 9, 12-30, and 33-ongoing
Principal Investigator(s): ● Oleg M. Alifanov, PhD, Kosmos International Educational-
Scientific Center, Moscow, Russia
RESEARCH OBJECTIVES
Developing a Procedure for
Radiosounding of the Satellite
Coverage Area using a Network of
Ground Receivers (Ten-Mayak)
studies very high frequency (VHF)
radio reception and transmittal signal
conditions from an onboard radio
beacon located on the International
Space Station (ISS) using the world
radio amateur network and
determine the characteristics of the
radio signals broadcasting and
retransmitting using an onboard
transceiver.
EARTH BENEFITS
Ten-Mayak is used in practical classes
in schools, ie, for holding collective
sounding signal receipt sessions,
which can be applied particularly
successfully and effectively in non-
classroom activities in high schools.
SPACE BENEFITS
The sum total of the data and calculations obtained on the current reciprocal positions of a
satellite and a ground receiver is a final product of the experiment, with which the main
characteristics of the procedure for space-to-ground radio sounding can be determined using
the ground radio amateur network to monitor plasma irregularities in the satellite coverage
area. The initial results of the experiment confirmed the principle feasibility of using the multi-
beam method of the satellite coverage area radio sounding.
RESULTS
During the experiment, sounding packets from the on-station radio beacon in the form of time
tags were emitted and received by the ground reception network, which included amateur VHF
receivers, and the measuring results were broadcast on the Internet. Numerous reports on the
