Problems solved by technology

Each joint adds an extra fastener and doubles the mass, and creates a potential soft joint that reduces overall structural rigidity
Furthermore, once a satellite has been assembled, it often requires post-assembly alignment and complex calibration procedures
[0004] Each step in such a process is an expensive and time-consuming
However, even more important than time and money, traditional designs lead to increased failure rates and misalignment problems when the satellite is in orbit
As can be appreciated, repairing a satellite can be extremely difficult when the satellite is already in orbit

Embodiment Construction

[0014] figure 1 A satellite 100 according to the present teachings is shown. figure 2 An "exploded" view of some salient features of satellite 100 is shown. now refer to figure 1 with figure 2 Both, the satellite 100 includes a unified payload module 102 , a propulsion module 114 , a payload antenna module 122 , a bus assembly module 132 and a solar array system 140 arranged as shown. It should be noted that figure 1 with figure 2 The orientation of the satellite 100 is "inverted" in the sense that, in use, the antenna 124 shown facing "up" will face "down" towards the Earth.

[0015] Unified payload module 102 includes panels 104 , 106 and 108 . In some embodiments, the panels are joined together in known manner using various connectors and the like. Brackets 109 provide structural reinforcement to the connecting panels.

[0016] Panels 104 , 106 , and 108 serve as radiators for radiating heat from satellite 102 , among other functions. In some embodiments, the pa...

Abstract

A satellite frame includes a one-piece integrated body defining a plurality of sides for attaching satellite components thereto. Use of the single integrated satellite body minimizes the amount of fasteners and alignment equipment and processes. Use of the single piece frame also allows for the maximum possible specific stiffness by greatly reducing the number of connections and structural interfaces.

Description

technical field [0001] The present invention relates to satellites, and in particular, to the structural design of LEO and MEO satellites. Background technique [0002] Traditional satellite structural designs typically consist of multiple panels, decks, stringers, ribs, and braces attached to each other to form a closed shape that defines a set of planar surfaces. Typical shapes will be rectangular or hexagonal prisms. [0003] A significant problem with this type of design is that it uses multiple parts and fasteners and requires extensive fixtures, support tooling and labor. Each joint adds an extra fastener and doubles the mass, and creates a potential soft joint that reduces overall structural rigidity. Furthermore, once a satellite has been assembled, it typically requires post-assembly alignment and complex calibration procedures. [0004] Each step in such processes is expensive and time-consuming. However, even more important than time and money, traditional des...
