- Delivery includes electrical power systems, batteries, and solar panels for a growing constellation.
- The company underscores transparency by introducing online pricing for its subsystems, in addition to previously released satellite bus pricing.
Vilnius, Lithuania, 02 September 2025 — Kongsberg NanoAvionics (NanoAvionics), a leading small satellite bus manufacturer and mission integrator, has shipped more than 50 power system components to one of its repeat constellation customers. The delivery includes CubeSat electrical power systems (EPS), battery packs, and fixed and deployable solar panels.
The undisclosed constellation operator, building its spacecraft in-house, is using NanoAvionics’ flight-proven power systems to expand its growing fleet. Several satellites in the constellation are already operational in orbit, powered by NanoAvionics components.
and Battery Packs
NanoAvionics’ CubeSat EPS can deliver up to 175 W of output power, battery packs offer up to 161 Wh capacity, and solar panels generate up to 75 W per triple-deployable wing. NanoAvionics‘ EPS 2.0 – originally developed for microsatellites – has also been integrated into CubeSat buses previously, providing up to 660 W of output power and greater energy storage capacity. This modularity is beneficial for a range of satellite missions, including power-hungry payloads that require high duty cycles.
The CubeSat EPS and power components are compatible with 6U, 8U, 12U, and 16U buses and can be customised for specific mission power needs.
NanoAvionics designs and assembles up to 80% of its satellite bus components in-house. This vertical integration enables three distinct paths for customers building constellations:
- Subsystem kits and avionics packages for full in-house assembly.
- Pre-integrated buses allowing flexible payload integration and testing.
- Fully integrated, flight-ready satellites offering the most risk-averse route to orbit.
With over 50 satellites launched and thousands of subsystems supplied, NanoAvionics’ satellite components have extensive flight heritage and proven reliability. The company has already supported more than 10 constellation operators worldwide across applications, including Earth observation, broadband, IoT, and signals intelligence.
Atle Wøllo, CEO of Kongsberg NanoAvionics, said, “Our objective is to offer customers flexibility and reliability for their space business, research, or national security needs. Even when customers decide to build their constellations in-house, they can benefit from NanoAvionics’ flight heritage, radiation qualification, quality assurance, and serial manufacturing expertise, de-risking the most crucial parts of their mission. Seeing returning constellation customers speaks to our product maturity and cost-effectiveness.”
In addition to supplying thousands of subsystems for global operators, NanoAvionics is one of the few space companies to make satellite bus and component pricing available online, with bus pricing available via the online configurator tool. This transparency enables customers to compare options early in their mission planning and supports more predictable constellation cost modelling.
NanoAvionics’ subsystems are immune to destructive single-event effects – life-critical components are tested against heavy ions, and subsystem-level tests are performed against 200 MeV proton beams and total ionising dose, following tailored ESCC 22900 and ESCC 25100 procedures. This qualification ensures long-term reliability and availability for critical missions.
NanoAvionics also offers a broad portfolio of satellite subsystems, including reaction wheels, magnetorquers, on-board computers, payload controllers, UHF radios, antennas, and CubeSat frames, as well as microsatellite power and attitude control systems.
