40:(acronym for Reconfigurable Platform for Observation, Telecommunications and Scientific Uses) is a 3-axis stabilized platform designed for mini-satellites weighing approximately 500 kg operating in low Earth orbit. The platform is used by six scientific satellites developed as part of the space program of the

operation in low orbits as platforms for various science and applications. After an industrial consultation with the national prime contractors of the time, Aérospatiale (Cannes) was selected, in May 1996, as industrial prime contractor, with the system to be built in the Cannes-Mandelieu space center.
136:
The PROTEUS platform and command and control segment has been developed based on a partnership between CNES and Aérospatiale (now Thales). The integrated team carries out the design of the PROTEUS multi-mission bus, the industrial production of the platform and associated satellites of which is the

Attitude control: the satellite is stabilized on 3 axes with a pointing precision of 0.15° (Jason-3). The fine sensors used to determine the orientation of the satellite are two three-axis star finder and three two-axis gyrometers. The coarse sensors are three-axis magnetometers and 8 solar sensors
88:
In 1993, CNES decided to launch the development of the PROTEUS mini-satellite program in parallel and jointly with the Jason-1 satellite, the first user for the platform. Program goals including meeting recurring requirements for satellite solutions in the 500 kg-700 kg class intended for

PROTEUS is a 3-axis stabilized platform designed for missions in low earth orbit for satellites with a total mass of approximately 500 kg, including 270 kg for the platform excluding propellants. Its main features are as follows:
92:
By 2010, the PROTEUS platform accumulated 20 years of on-orbit success, with the five satellites that had been orbited: Jason-1, CALIPSO, CoRoT, Jason-2, and SMOS.
118:
Propulsion: liquid propellant rocket motors burning hydrazine with a Delta-v capacity of about 120 m/s. The mass of hydrazine carried is 28 kg (Jason-3).
