Cubesat Solar Panel Protection

The high power generation capabilities radiation and temperature resilience ensure smooth space operations.

Cubesat solar panel protection.

With standard size of solar cell strings it is not possible to construct a reliable solar panel for cubesat with redundant strings interconnection. The high power generation capabilities radiation and temperature resilience of the solar panel ensure smooth space operations. Modular solution multiple pc104 form factor board ideal for 3u platforms and up communication over two independent i2c or uart interfaces spi optional fram based mcus for improved radiation tolerance hardware over current protection and hardware based maximum power point tracking hardware supervisor including watchdog solar panel interface utilizes gan fets output load channels. The modern system has on board monitoring and logging features.

The isis single cubesat solar panels come in 1 2u size with sun and temperature sensors and other custom options available on request. The gtosat mission is a scientific mission developed by nasa gsfc the aerospace. Its space qualified cells are provided with extensive characterization and test reports. Nanoavionics cubesat electrical power system eps is highly standardized power conditioning and distribution unit designed to meet wide variety of customer requirements.

Good power management is also vital to maximise efficiency and safety on board. Solar panels are manufactured following the standard ecss e st 20 08c. Cubesat deployalbe solar panels power system nanospacecraft solar panel deployment testing modular design abstract one of the main cubesat bus limitations is the available on board power. Flight heritage since 2013.

The eps is compatible with different size and configuration of solar panels. The most common failure of cubesats is negative power budget. The maximum power obtained using body mounted solar panels and advanced triple junction solar cells on a triple unit cubesat is typically less than 10 w. The x y solar panel supports multiple integrated sensors and is fully compliant with the cubesat standard.

Dhv cs 10 products are solar arrays for 1u cubesats there are available top bottom and side versions. Cubesat picosatellites have a limited area of walls for solar cells assembling and the available area has to be effectively shared with other parts such as planar antennas optical sensors camera lens and access port. The solar cells are azur space 3g30c qualified solar cells for space applications with 30 efficiency using triple junction technology. Dhv technology has signed a contract with nasa goddard space flight center to provide the solar panels of the gtosat mission geostationary transfer orbit satellite.

It supports multiple integrated sensors and it is fully compliant with the cubesat standard. Tailored solar panel configuration to match orbit mission is more important than solar cell area.
