[CO-WoP'2025] CNES-ONERA Workshop on Earth-space radiowave Propagation
TSI - Traitement du Signal et des Images
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

The JUICE Lunar-Earth Gravity Assist: from Inception to Completion
ORB - Mécanique Orbitale
In
August
2024,
the
JUICE
spacecraft
performed
a
very
special
manoeuvre:
the
first-ever
Lunar-Earth
gravity
assist
(LEGA)
manoeuvre.
The
concept
was
invented
at
ESOC
in
Summer
2013.
In
a
first
phase,
the
potential
of
the
concept
was
analysed
in
detail
by
mission
analysis,
and
its
navigability
was
carefully
studied
to
ultimately
include
it
in
the
JUICE
baseline.
Once
in
flight,
the
key
was
accuracy
and
safety.
These
aspects
were
successfully
handled
by
the
