Abstract:
Method and apparatus to efficiently launch spacecraft from underwater. Unfortunately, the prior art processes of launching spacecraft from sea either make no use of water buoyancy or waste use rocket fuel to overcome water resistance. As a result, payloads are smaller than are ideal. The instant invention however adds water buoyancy to increase the overall thrust of the spacecraft and therefore makes the spacecraft more efficient than if launched outside of water.
Abstract:
A spacecraft includes a plurality of deployable module elements, at least one of the deployable module elements including a robotic manipulator, the spacecraft being reconfigurable from a launch configuration to an on-orbit configuration. In the launch configuration, the deployable module elements are disposed in a launch vehicle in a first arrangement. In the on-orbit configuration, the deployable module elements are disposed in a second configuration. The spacecraft is self-assembled by the robotic manipulator reconfiguring the spacecraft from the launch configuration, through a transition configuration, to the on-orbit configuration. The deployable module elements may be in a stacked arrangement in the launch configuration and may be in a side-by-side arrangement in the on-orbit configuration.
Abstract:
A “black box” space vehicle solution may allow a payload developer to define the mission space and provide mission hardware within a predetermined volume and with predetermined connectivity. Components such as the power module, radios and boards, attitude determination and control system (ADCS), command and data handling (C&DH), etc. may all be provided as part of a “stock” (i.e., core) space vehicle. The payload provided by the payload developer may be plugged into the space vehicle payload section, tested, and launched without custom development of core space vehicle components by the payload developer. A docking station may facilitate convenient development and testing of the space vehicle while reducing handling thereof.
Abstract:
The present invention concerns a method for making a microsatellite, comprising providing: modules of a first type configured to house electronic boards of a microsatellite; modules of a second type configured to house devices and systems of a microsatellite; and modules of a third type comprising first and second interface means configured to be coupled to a launch vehicle and to external appendages of a microsatellite, respectively; said modules of a third type being designed to cause a body of a microsatellite to have a predefined height; wherein all the modules of the first, second and third types are configured to be stacked regardless of the type. The method further comprises making a body of a microsatellite by stacking modules of different types, wherein the stacked modules include at least one module of the second type and at least one module of the third type.
Abstract:
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.
Abstract:
A system and method for wirelessly communicating between a host bus of a spacecraft and a secondary payload. In one configuration, the host bus and secondary payload each include a wireless interface for establishing a radio or optical communications link thereby allowing for the elimination of a complex wiring harness connected between the host bus and the secondary payload.
Abstract:
The invention relates to a method for transferring a space payload from a first orbit to a second orbit. Said method is characterized in that the space payload, moving about the first orbit, is attached to a removable orbital towing assistance device including at least one fuel pouch. Said method includes the steps of: —attaching (E1) an orbital transfer vehicle to the removable orbital towing assistance device; and —transferring (E2) the space payload and the removable orbital towing assistance device to the second orbit by means of the orbital transfer vehicle. The invention also relates to a removable orbital towing assistance device intended for a space payload and an orbital transfer vehicle and enabling direct supply of fuel to the vehicle and/or the space payload.
Abstract:
A method of cooling spacecraft electronics by transferring fuel between two or more satlets is provided. Each satlet's electronics is thermally coupled to the satlet's fuel tank. A controller connected to a temperature sensor determines that a temperature of a first satlet's electronics is reaching, has reached, or exceeds a predetermined threshold. The controller connected to a second temperature sensor determines that a temperature of a second satlet's propellant is lower than the temperature of the first satlet's electronics. The controller then directs the flow of propellant from the second satlet's fuel tank to the first satlet's fuel tank to cool the first satlet's electronics.

A satellite system includes a chassis, an avionics package included within an upper portion of the chassis. The avionics package includes a main system board, a payload interface board, at least one daughter board and a battery board. The main system board, the payload interface board, the at least one daughter board, and the battery board reside in substantially parallel planes. The payload interface board, the at least one daughter board, and the battery board are coupled to the main system board through one or more stackable connectors. A method of operating a satellite is also described.
Abstract:
An artificial satellite system includes at least two panel type artificial satellites closely connected with a plurality kind of multi networks and the minimum necessary essential tools for one artificial satellite installed on a substrate of each panel type artificial satellite, wherein the multi networks are formed by a communicating network for communicating data among data processing tools installed on each of the panel type artificial satellites, a heat pipe for providing thermal energy among tools installed on each of the panel type artificial satellites and a battery supplying line for connecting battery controlling devices installed in the each panel type artificial satellite so that the artificial satellite system can maintain higher and various controlling performance with a back-up effect of the multi network in the case that any function tool is damaged in one of the panel type artificial satellite.
