Description
This abstract focuses on the Sodern Navigation Cameras for Jupiter Icy moon Explorer (JUICE) and Mars Sample Return Earth Return Orbiter (MSR-ERO). The Cameras are custom made with TRL FPGA inside to withstand constraints of radiation environment and high observation capabilities. The first one is named NAVCAM for Navigation Camera, the camera is a key instrument for the spacecraft navigation, it assesses the position of the moon and stars in its field of view in an inertial reference frame. The second one is named NAC for Narrow Angle Camera, the camera is dedicated for the rendezvous and the capture of a football-size object called the Orbiting Sample (OS) in Mars orbit. NAVCAM is based on Sodern HYDRA Star Tracker experience with the HAS2 sensor. Digital control is performed with a FPGA RTAX2000S driving the sensor, MRAM memory with correction parameters, and 1Gb SDRAM for image summation. NAC is based on Sodern HORUS Star Tracker experience with the Faintstar sensor. Digital control is performed with a ProASIC3L FPGA driving the sensor and 1Gb SDRAM memory for image storage.
