KOREASAT 6A to embark a
satellite-based augmentation system (SBAS) payload
built
April 6, 2023
KT SAT Corporation Ltd. (KT
SAT), Korea, and Thales Alenia Space, are announcing
today that KOREASAT 6A will also embark a
satellite-based augmentation system (SBAS) payload
to improve the continuity and availability of the
Korea Augmentation Satellite System (KASS).
Developed since 2016 by Thales
Alenia Space jointly with the Aerospace Research
Institute (KARI), KASS is similar to the European
Geostationary Navigation Overlay Service (EGNOS). It
improves the positioning and navigation performance
provided by global navigation satellite systems
(GNSS) for a number of different sectors, especially
aviation. It has been developed to meet
international standards by International Civil
Aviation Organization (ICAO), improving the accuracy
and reliability of global positioning system (GPS)
signals and better ensure flight safety and
efficiency, while also reducing the environmental
impact of air travel.
KASS is expected to improve the
GPS position error to 1.0-1.6 meter from the current
15-33 meter level in real time to ensure positioning
reliability throughout the country. Also KASS has
been considered as a future technology as it could
be applied to various fields, mainly public safety,
transportation, defense and science.
