The Chinese-French mission SVOM due to be launched in 2023 is the next generation of missions fully dedicated to the survey of the transient sky thanks to an agile spacecraft embarking a multi-wavelength science payload associated with a network of ground robotic nIR/optical telescopes. The SVOM core instrument is the 4–150 keV 2-D coded mask camera ECLAIRs responsible for the autonomous search and trigger of transient events within its field of view. The flight model of ECLAIRs has been built by several French labs (IRAP, CEA, APC) under the supervision of the French Space Agency (CNES). In 2021, intensive on-ground calibration has been performed on the ECLAIRs camera. Here, we give an overview of the calibration sequences of the ECLAIRs flight model and we present an overview of the main instrument performances.

PHARAO (Projet d'Horloge Atomique par Refroidissement d'Atomes en Orbite), which has been developed by CNES, is the first primary frequency standard specially designed for operation in space. PHARAO is the main instrument of the ESA mission ACES (Atomic Clock Ensemble in Space). ACES payload will be installed on-board the International Space Station (ISS) to perform fundamental physics experiments. All the sub-systems of the Flight Model (FM) have now passed the qualification process and the whole FM of the cold cesium clock, PHARAO, is being assembled and will undergo extensive tests. The expected performances in space are frequency accuracy less than 3.10-16 (with a final goal at 10-16) and frequency stability of 10-13 τ-1/2. In this paper, we focus on the laser source performances and the main results on the cold atom manipulation.
