06 07 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 (Under consideration) 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. Telescope Sodern leveraged its heritage with piezo Driving Electronic : (Under development) • Ampli mechanisms and optronic detection to • Laser Emitter & Pointing Acquisition & Tracking develop this device. Receiver (Under consideration)

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.

1550 nm 1.5 dB insertion loss Up to 96 x 96 ports

08 CAMERAS & FILTERS

ARAMIS (UNDER DEVELOPEMENT) The Approach and Rendez-vous Automated Multi-mission Integrated Sensor (ARAMIS) is a rendez-vous sensor that uses advanced algorithms for non-cooperative approach, proximity operation and docking.

Non-cooperative vision-based navigation with 6 degrees of freedom Autonomous from long distance detection to the final approach High-Performance & robustness Smart design

AURICAM (UNDER DEVELOPEMENT) Auricam is a compact, affordable camera designed spacecrafts’surroundings. Several field of views are possible depending on customers needs.

CMOS camera from 1 to 4 Mpixel Compact design 35 degree fields of view available

STRIP FILTERS Strip filters are designed to be assembled on detectors to form a multi-spectral detection module for Earth Observation missions. Sodern offers high radiometric and spectral performance, high flexibility (design, spectral characteristics, number of stripes), and very high precision assembly.
