Space vehicle chassis
A modular space vehicle chassis may facilitate convenient access to internal components of the space vehicle. Each module may be removable from the others such that each module may be worked on individually. Multiple panels of at least one of the modules may swing open or otherwise be removable, exposing large portions of the internal components of the space vehicle. Such chassis architectures may reduce the time required for and difficulty of performing maintenance or modifications, may allow multiple space vehicles to take advantage of a common chassis design, and may further allow for highly customizable space vehicles.
1. An apparatus, comprising:
a plurality of panels covering respective sides of a space vehicle; and
a plurality of modules comprising at least three modules, wherein
at least one of the plurality of panels is connected to another panel of the plurality of panels, one or more internal components of the space vehicle, or both, such that the at least one panel of the plurality of panels opens away from the one or more internal components of the space vehicle, allowing access to internal components on a respective side of the space vehicle, and
a first module comprises an antenna and a housing for radio frequency equipment, a second module comprises batteries, solar panels, charging circuitry, and at least one power supply, and a third module houses a backplane and circuit boards.
2. The apparatus of claim 1 , wherein the apparatus comprises four panels, each panel connected to at least one other panel via a hinge.
3. The apparatus of claim 2 , wherein one panel is connected to a backplane of the space vehicle, and the other three panels open to expose three sides of the one or more internal components of the space vehicle.
4. The apparatus of claim 2 , wherein all of the panels are connected to one another by at least one hinge.
5. The apparatus of claim 1 , wherein at least one panel of the plurality of panels provides radiation shielding, thermal mass, and a thermal control surface.
6. The apparatus of claim 1 , wherein
each module of the plurality of modules is connected to at least one other module of the plurality of modules and each module can be removed from the other modules so components of the removed module may be worked on without disturbing components of the other modules.
7. The apparatus of claim 1 , wherein each module plugs into at least one other module via at least one respective connector.
8. The apparatus of claim 1 , wherein the plurality of modules comprise a top module, a middle module, and a bottom module.
9. The apparatus of claim 1 , wherein the third module comprises at least one panel that opens to expose the one or more internal components.
10. The apparatus of claim 1 , wherein the third module comprises a panel, the panel comprising a plurality of open slots to access debugging connectors on individual circuit boards when the panel is closed.
11. The apparatus of claim 1 , wherein the third module comprises a panel, the panel comprising attached ballast masses for center of gravity symmetry.
12. The apparatus of claim 11 , wherein another panel attaches to the backplane, and yet another panel comprises an attached sun sensor.
13. The apparatus of claim 1 , wherein
the plurality of modules comprise a top module, a center module, and a bottom module, the top module is connected to the center module, and the center module is connected to the bottom module, and
each module may be removed from the other modules so components of the removed module may be worked on without disturbing components of the other modules.
