[CO-WoP'2025] CNES-ONERA Workshop on Earth-space radiowave Propagation
TSI - Signal and image processing
The
objective
of
this
workshop
is
to
present
research
activities
concerning
Earth-space
radiowave
propagation.
It
will
address
the
following
applications:
NTN
(Non
Terrestrial
Networks
including
mega-constellations),
mobile
communications
for
5G
and
6G,
GNSS
(Global
Navigation
Satellite
Systems),
remote
sensing
and
radio-occultation.
The
targeted
frequency
bands
range
from
HF
to
EHF,
that
is
from
3 MHz
to
300 GHz.
Issues
related
to
standardization,
e.g.
for
ITU-R
(International
Telecommunications
Union
–
Radiocommunications
sector)
and
new
frequency
