Design and Prototyping of a Solar Panel Deployment
and Tracking System for PocketQube Nano-Satellite
Background• Modularised Nano-Satellite, such as the 5cm*5cm*15cm PocketQube,
have great potential, however are restricted by limit energy supply.
• Currently, only fixed solar panels available for PocketQube, for the
bigger Cubesats, the solar panels have no solar tracking feature.
• Our co-operator Alba Orbital (PocketQube Shop), is a Glasgow-
based aerospace start-up and world’s leading developer of PocketQube.
Objective• According to Alba Orbital’s requirement, the system should mount 6
deployable solar panels, and the mass should less than 200 grams.
• Alba Orbital wish to use feasible and verified technologies, to develop a
reliable product for launches in 2016. Therefore a prototype is
encouraged to build if possible. Compact is design is needed.
Result• Mass: 168±5g for the 3D printing ABS edition; 182±5g for the CNC alloy edition. Efficiency: 4 times compare to the fixed method, 5 times with add-on.

Gimbal Gearbox Design
and Rapid PrototypingVibration AnalysisStructural response spectrum for the panels are
made by Abaqus CAE finite element analysis.
Dynamics Analysis
• Gearbox reduction ratio (all gears in 0.5 mod):
Vertical 10-22 (1:2.2)
Horizontal 8-28=22-80 (1:12.7)
• A custom double crown-spur gear is utilized to
connect the pinion gear and internal gear
compactly, meeting the strict demand of space.
• By comparing the quotes globally, all custom
gears, bearings and high-accuracy 3D printing
structures for the gimbal prototype cost only
£52.7.

General Design
Analysis Methods• Trade-off analysis is done to meet the balance
of low weight, larger panel dimension, and
higher efficiency. Cost, manufacturability and
also reliability are considered from the first
phase, as commercial production is expected.
• Optimisation designs and comparisons are
made to continuously improving performance.
• Motion Analysis in both theoretical mechanics
and Solidworks motion analysis are attempted.
• Finite Element Analysis to test the vibration
response and stress analysis of the shaft hinge.
