Picard was a CNES solar-observation microsatellite built around the Myriade platform. Its SODISM telescope measured solar images, diameter and limb shape; SOVAP and PREMOS measured total and spectral irradiance. Precise Sun pointing and thermal stability supported comparisons of brightness, geometry and solar oscillations. Common payload electronics handled command sequencing, telemetry formatting, thermal regulation and image compression.
