As traditional satellites have been successful in use of foldable or extensible structures, the way of space mission in nano-scale satellites can be greatly extended by having deployable structures. Especially for remote sensing, such structure makes it possible to get long focal length. In Intelligent Space Systems Laboratory (ISSL) of the Univers...

Topology optimization (TO) has been a useful engineering tool over the last decades. The benefits of this optimization method are several, such as the material and cost savings, the design inspiration, and the robustness of the final products. In addition, there are educational benefits. TO is a combination of mathematics, design, statics, and the...

... To date, PRISM is the only deployable telescope to be launched to orbit. However, the instrument did not achieve the required performance specification, as the deployed secondary mirror did not attain a stable position [17]. Secondary mirrors, once deployed to their intended position, have to be aligned to achieve the required focus position. ...
The total volume of a satellite in its launch configuration is constrained by the volume available within the payload fairing of the launch vehicle. This constrains the size of the payloads on the satellite. For a high-resolution Cassegrain optical payload, there is scope to save the empty space between the primary and secondary mirror by stowing the secondary mirror during launch and deploying it to the operational configuration once the satellite reaches orbit. Successful implementation of the concept to a flight conical deployable baffle is presented. Further, the concept is extended to a deployable telescope with a controlled deployment mechanism. This work follows the proposed passive mechanism, consisting of constant torque spring-driven wires to pull out the concentrically stowed cylindrical barrels of the telescope in a telescopic configuration. We present the configuration, design and development for an optical payload on a small satellite.
