The technology of the UltraSPARC-1 is two-thirds Swedish, and a third American. The brain, controls the computer, comes from ÅAC in Uppsala.
The harsh space environment is a major challenge for teeny electronics. The Company AAC Microtec is known to reduce microelectronics and make sure it can handle rugged demands. When it comes to nano-satellite Sparc 1 you contribute with specialized knowledge and several key components.
– A major challenge is that the satellite is in orbit around the world have to cope with many large temperature changes. It passes the sunny side and the shadow side around 15 times a day and it can range from minus 20 to plus 55 degrees, said Robert Lindengren, Product Manager at AAC.
In addition, it must meet the cool showers with aggressive cosmic radiation in space and can knock out electronics, as well as the strong vibrations that occur in the atmosphere layers.
In the US contributes AFRL with components and expertise in a” plug-and-play technology “for space, but it also cooperates with AAC when it comes to satellite construction.
ÅAC, which is a spin-off from the Ångström Laboratory, will include the development of on-board computer that controls the entire satellite. Inside it is the central software controlling assignments, processor and RAM.
The power system includes solar panels from the US, lithium-ion batteries from a Nordic engineering and circuit boards for power distribution – also from AAC – which distributes and monitors the power supply of the components in the path around the Earth.
Robert Lindengren be ensure that satellite technology also works with the loads hung on Sparc-1.
The advanced optical camera (indicating position in space images) made by Swedish Defence Research Institute, along with AAC. FOI is also developing SIGINT receiver, while the software radio is used for data coming from the US.
