IAI Improved Multi Purpose Satellite bus

IAI Improved Multi Purpose Satellite bus is the Israeli micro-satellite bus associated with the VENuS Earth-observation spacecraft ^[1][2]. VENuS was a joint CNES and Israel Space Agency mission, with Israeli-side spacecraft responsibilities and IAI and Rafael manufacturing participation in public mission summaries ^[1][2]. The bus-family label is ambiguous between IMPS, Improved Multi Purpose Satellite, and OPSAT 3000 ^[2][1]. VENuS mission records give 260 kg launch mass and 800 W spacecraft power, placing the platform in the mini class ^[1]. The spacecraft carried the VSSC superspectral camera for high-resolution land observation in sun-synchronous orbit ^[1][2].
