RESEARCH OBJECTIVES
The Study of a High-Precision
System for Predicting ISS
Motion (Vektor-T) verifies the
International Space Station
(ISS) motion prediction
methodology that has been
developed for improving the
ISS motion determination and
prediction accuracy as
compared to the nominal
orbital determination and
prediction system currently in
operation. To accomplish this
task Vektor-T utilizes
navigational measurements of ISS motion using both the ground tracking station radar systems
and the Global Position System (GPS) and GLONASS navigation satellite system receivers.
SPACE BENEFITS
As a result of the Vektor-T experiment, a pilot high-precision system for predicting the ISS
motion will be developed. Operating this system will improve the ISS motion determination
accuracy and will provide precise navigational correlation for the results of the experimental
and research activities performed on the ISS, as well as for other station flight control tasks.
RESULTS
The phase of development testing of navigation satellite data processing methodologies to
address ISS motion determination tasks has currently been completed, and work has begun on
the task of configuring a high-precision system for predicting the ISS motion using the following
as a basis: the developed models of perturbations impacting the ISS; the motion determination
and prediction methodologies; and the experimentally refined ISS motion prediction model
parameters.
This investigation is ongoing and additional results are pending publication.
