Design Engineering and Construction
The design of KiwiSAT is based on the Microsat formula and is basically a system of trays clamped together in a box shape. Solar Cells cover exterior to charge the batteries which are the prime power source for all on-board systems.
Various antenna are mounted on the top and bottom of the satellite it such a way as to give an excellent radiation pattern thus reducing signal strength variations common in many small satellites.
The satellite systems have been broken down into, Linear Transponder, FM Transponder and Command System, Power Supply, On-board Computer (Integrated Housekeeping Unit - IHU), Science Package and Structure.
Separate teams are developing each part yet maintaining close contact.
Structure is complete through to flight status. Work is now centred on integration into final satellite form when some final adjustments will be made ready for launch.
The antenna configuration developed for best performance limits the choice of launch vehicles due to final release requirements. This does not significantly limit the launch opportunities neither does it limit the choice of a suitable orbit. (Video)
Construction of the final unit is in the hands of Fred kennedy, ZL1BYP who has prior experience in the satellite field by contributions to AO-40 and other projects.
Sub-assemblies have been assembled in various centres throughout New Zealand making this a truly nation-wide project.
