OPTICAL COMMUNICATIONS
& MODULAR PAYLOADS LASER LINKS
Data transmission via laser links offers higher throughput & security than radio-frequency.
A laser link terminal is made of 4 building blocks including a laser modem, a fine pointing device,
a beam expanding telescope, & a coarse pointing gimbal, and connects satellites
to the ground (feeder links) or to other satellites within a constellation.
Gimbal

FINE POINTING DEVICE
(UNDER DEVELOPEMENT)
An optical sensor is used to track the
received beams and actuate a fine steering
mirror to optimize the transmission.

COARSE POINTING GIMBAL (UNDER DEVELOPEMENT) High data
Its function is to point the larger beam on the other terminal according transmission
to its coarse position.
The gimbal has two axes of rotation in order to be able to reach any No interference
other satellites. Compact design
BEAM EXPANDER TELESCOPE (UNDER DEVELOPEMENT)
The function of the telescope is to expand the diameter of the laser.
A laser beam means that the laser energy is more concentrated by the emitting terminals, and more
energy is collected by the receiving terminals. The telescope is manufactured thanks to advanced
mirrors fabrication technologies and innovative integration methods.
OPTICAL SWITCH
(UNDER DEVELOPEMENT)
The switch matrix is an innovative solution to manage photonic signals
in a communication payload.
The switch enables remote interconnection of a large number of fiber
channels (up to 96 x 96) with very low insertion loss thereby providing
a high degree of flexibility to the payload architecture.

10EQUIPEMENT FOR SATELLITES
Our star trackers allow satellites and spacecraft to orient
themselves by detecting, identifying and measuring the
direction of the stars. Their role is thus essential to ensure
that the satellites function correctly. Our rendez-vous sensors
guide space vehicles to their destination in orbit, and make it possible
to meet and dock between celestial objects. Our optronic technologies
integrated into Earth observation satellites, contribute to our knowledge of
the climate, the ecosystem, the geography and the wonders of our planet.

INSTRUMENTS
We proudly participate in extraordinary programs
pushing the envelope of humanity’s scientific knowledge.
Examples include the PHARAO cesium atom clock which will be
installed on the International Space Station, the heart of NASA InSight’s
seismometer to study Martian seismology, and the Pockels cells for the
Megajoule Laser. These instruments perfectly exemplify Sodern’s technological
prowess and strong desire to innovate and seek solutions to challenging
problems. We have applied this creativity and tenacity to improve our internal
processes thereby revolutionizing our competitiveness and efficiency.
