20110267229 | Distributed Distance Measurement System for Locating a Geostationary Satellite - A distance measurement system for locating a geostationary satellite equipped with a transponder includes: a central station emitting a distance measurement signal; and at least one measurement station receiving the emitted signal, including means for measuring the time of arrival of the emitted signal, and transmitted via the transponder of the satellite. The central and measurement stations, of known positions, include synchronization means with a common time base. The transponder is that of a satellite telecommunications system, and has a bandwidth B. The central station includes means for emitting a specific distance measurement signal, distinct from the telecommunications signals transmitted via the transponder, with periodic events and with spread spectrum, the bandwidth of which is included in B. | 11-03-2011 |
20130292516 | Propulsion System for Satellite Orbit Control and Attitude Control - A propulsion system for the orbit control of a satellite with terrestrial orbit having an angular momentum accumulation capacity comprises a propulsion unit able to deliver a force along an axis F having a component perpendicular to the orbit, and a motorized mechanism connected on the one hand to the propulsion unit and on the other hand to a structure of the satellite, the motorized mechanism being able to displace the propulsion unit along an axis V parallel to the velocity of the satellite, and able to orient the propulsion unit so as to make it possible to control: a component of the force along the axis V, for orbit control, an amplitude and a direction of couple in a plane perpendicular to the axis F, for control of the angular momentum. | 11-07-2013 |
20130313369 | PROPULSION SYSTEM FOR CONTROLLING THE ORBIT AND CONTROLLING THE ATTITUDE OF A SATELLITE - A propulsion system for controlling the orbit of a satellite in earth orbit comprises a thruster suitable for delivering a force along an axis F, and a motor-driven mechanism linked on the one hand to the thruster and on the other hand to a structure of the satellite, said motor-driven mechanism being suitable for displacing the thruster on either side of the plane of the orbit and suitable for orienting the thruster so as to make it possible to control a component perpendicular to the orbit of the force in two opposite directions, to control the inclination of the satellite, and in that said motor-driven mechanism is suitable for displacing the thruster along an axis V parallel to the velocity of the satellite, and suitable for orienting the thruster so as to make it possible to control a component of the force on the axis V, to control orbit. | 11-28-2013 |

20140097981 | SATELLITE WITH DEPLOYABLE PAYLOAD MODULES - A telecommunication satellite with geostationary orbit comprises an upper module, a lower module, and a lateral module, disposed in a storage configuration between the upper module and the lower module, and deployed to an operational configuration of the satellite in the orbit by a rotation in relation to an axis Z oriented towards the earth in the operational configuration. The lateral module comprises two substantially plane and mutually parallel main surfaces, termed dissipative surfaces, able to dissipate by radiation a quantity of heat generated by facilities of the satellite; the dissipative surfaces being, in the operational configuration, held in a manner substantially parallel to the plane of the orbit, making it possible to limit the solar flux received by the dissipative surfaces and to optimize the quantity of heat dissipated by the lateral module. | 04-10-2014 |
