    摘要: Ground stations 20, 21 receive any signal transmitted by a geostationary artificial satellite 10, and store the reception signal together with the reception time thereof. A difference Δt in reception time of a same signal between the ground station 20 and the ground station 21 is calculated by performing correlation processing of the reception signal of the ground station 20 and the reception signal of the ground station 21. A distance R20 between the ground station 20 and the geostationary artificial satellite 10 is measured by a distance measurement device. A distance R21 between the ground station 21 and the geostationary artificial satellite 10 is calculated on the basis of the distance R20 obtained by measurement and the difference Δt in reception times, as obtained by correlation processing.

    摘要: The invention concerns a method and a device for integrating satellites on a launcher. The method aims at simultaneously integrating several satellites (14) on a common launcher and consists in equipping the latter with a support (10) such as a mast. Each satellite (14) is linked to the mast by several fixing mechanisms (22), independent of one another. Each mechanism (22) comprises a first interface member fixed on the satellite and a second interface member linked to the first interface member through a linking device capable of being disconnected. When docking, a streamlined cowl covering the linking device is received in a corresponding slot (18) of the mast (10). The second interface member is then fixed on the mast (10), from inside the latter, and then the cowl is removed.

    摘要: An improved and simplified system for densifying a cryogenic liquid for space vehicles is provided, which includes a heat exchanger (102) having heat exchange tubes (104) therein for receiving a flow of liquid from a storage tank, for example a liquid propellant (22) in a vehicle storage tank (20). The heat exchanger (102) is filled around the exchange tubes (104) with a two-component bath (112), the volume of a primary component substantially exceeding the volume of a secondary component. The secondary component has a boiling temperature that is lower than the boiling temperature of the primary component, and both are lower than the boiling temperature of the cryogenic liquid. In one example, the liquid to be densified is oxygen, the primary component is liquid nitrogen, and a secondary component is liquid hydrogen. The secondary component is preferably injected into the heat exchanger (102) in separate flows to prevent localized freezing of the first component. A manifold having a plurality of injectors may be used for introducing the second component to the heat exchanger (102). A control system (116) receives inputs from one or more sensors within the heat exchanger (102) and operates valves that control the flow of the first and second components of the heat exchange bath (112).

    摘要: A self-contained fueling module (10) provides the exact amount of hydrazine necessary to fuel a satellite (50) prior to launch. The fueling module (10) includes a propellant tank (14), a vacuum tank (12) and a pressurant tank (16). The propellant tank (14), filled with hydrazine, is shipped to the launch site where it is installed in the fueling module (10). Prior to launch, the fueling module is connected to the satellite and hydrazine is driven with Helium pressurant into the satellite fuel tank (52). The Helium also pressurizes the satellite fuel tank (52) to flight pressure. Any remaining fuel is evacuated from connection (45) and fuel transfer lines (42) with the vacuum tank. Personnel do not have to wear self-contained atmospheric pressurized environment (SCAPE) suits because there is no risk of hydrazine exposure.
