The Micro-Satellite Modular Structure

The USUsat micro-satellite platform utilizes a novel patent pending versatile structure that can be configured to your needs and mission. This new structure is designed with a standard OrthoGrid bolt pattern with integrated components to reduce manufacturing and assembly operations. The 13x13x18.5” structure is developed to provide stiffness, packing volume and versatile configuration to welcome subsystems and additional payloads. The principal merits of the structure are modular configuration, simplicity and assembly friendly.


The USUsat structure is highly integrated and addresses not only versatile design but integration and test as well

Configuration

The USUsat II bus is mainly designed for a panel-mounted configuration, which has all the internal components directly attached to the side panels. However in order to increase mounting surface, the structure can accommodate light weight shelves with the same bolt pattern connected horizontally. The top panel of the structure can be removed to have an open high deck for your external instrument. Another possibility is to configure a side panel with a large access window that exposes internal instrument to the outside. Instruments can be bolted on either the inside or outside of the structure.

 


Additional shelves can be added for payloads or subsystem components if needed
