Software Development of M6P Nano-Satellite Bus

For Nano-Satellite missions, the software is like the glue which holds all the subsystems together and ensures that they effectively communicate with each other as well as mission control center. The development of M6P nano-satellite buse‘s software is happening entirely in-house, involves rigorous and complex processes, collaboration with all technical departments and testing the code in simulated and of course real life environment by uploading the code to a fully functioning satellite in orbit.

NanoAvionics clients‘ needs are at the center of innovations and we are glad to offer remote software testing opportunity for each client who is in the process of payload development. Every client project has a dedicated FlatSat of M6P satellite bus and a client can connect to it and do the tests from a convenient location, in real time, and get advices from our developers. Any latest software improvements made by NanoAvionics team immediately appear in all FlatSats to enable clients working with the latest cutting-edge technologies.

The user interface of M6P is built with user-friendliness in mind – that any client without deep technical knowledge could operate satellite with a set of high-level commands.

And last, but not the least, our software development team is proud to have a fully integrated Continuous Integration system into their development process – a practice that merges all latest code versions several times a day whenever any changes are made. Each check-in is then verified by an automated build ant tests suite, allowing the team to detect problems early. The system is like an invisible colleague doing code checks 24/7!

All of the M6P nano-satellite bus subsystems found to be radiation tolerant to 20krad, after the product qualification tests

Nanosatellites such as those based on the M6P satellite bus must be designed to survive the radiation environment in LEO for several years. Only a program of rigorous testing can make commercial satellite operators confident that their satellites will function throughout the mission lifecycle. At NanoAvionics we test our nanosatellite buses and their subsystems regularly, as part of the product qualification process.

Recently, we completed an all-systems radiation test of our M6P multipurpose nanosatellite bus – we simulated a 5-year mission by exposing the M6P’s subsystems to a Cobalt-60 radiation source. The gamma rays generated by the isotope’s decay produced a 20 kRad radiation dose – a worst-case scenario for the internal systems of a satellite that spends 5 years in LEO, at an altitude up to 1000km. The Flight Computer, Electrical Power System, Payload Controller and all other subsystems of the M6P remained fully functional after the tests. These updated test results imply that the expected in-orbit lifetime of M6P and its separate subsystems is minimum 5 years, and in nominal conditions – 10-20 years.

Such a long on-orbit lifespan was once only possible with much larger satellites. The 6U-sized M6P, with its payload volume up to 5U, can support such long-duration LEO missions thanks to its 20kRad radiation tolerant subsystems and integrated chemical propulsion system. Enabling Chemical Propulsion System (EPSS) uses a green monopropellant to perform high-impulse orbital maintenance maneuvers and atmospheric drag compensation maneuvers that extend the satellite’s on-orbit service life.

Manufacturing Electrical Power System of M6P Nano-Satellite Bus

We offer you to have a glimpse at how our Electrical Power System (EPS), the very heart of M6P (and every nano-satellite), is being manufactured. EPS is responsible for controlled supply, flow, and storage of energy for other subsystems and mission’s payload – critical functions, to say the least. This in-house designed, highly efficient and fail-safe subsystem is truly versatile – suitable for all types of payloads – the ones which require high average orbit power and the others – which functionality is based on high peak output power.

The EPS is just part of the whole set of M6P subsystems – every one of them designed with versatility in mind, and being the reason why our Customers choose M6P nano-satellite buses for their small payload missions – amazing performance, no hardware adjustments needed, and extreme cost-effectiveness.

Manufacturing Mechanical Parts of M6P Nano-Satellite Bus

NanoAvionics’ M6P nano-satellite buses have around 150 mechanical parts, which are being designed, analyzed and manufactured with the highest precision and advanced industrial technologies. Have a look at this sneak-peak video illustrating how we produce some of these mechanical parts at Ekstremalė.

Few highlights of the mechanical processing we bring into play:
– The highest quality age hardened aerospace grade aluminum alloys are being used
– Most of aluminum part surfaces are hard anodized to provide hard wearing and electrically isolating protective layer.
– We use most sophisticated industrial balancing technologies
– All the mechanical parts are weight and stiffness optimized using finite element analysis.
– Electrochemical etching is being used in the manufacturing of the propulsion system
– The sealing surfaces are being polished using precision electrolytic polishing
– Pressure vessels used in the propulsion system are checked with non-destructive testing techniques
