MPBUS – Modular Power BUS for Space Vehicles


MPBUS is a decentralised power distribution architecture for spacecrafts, capable to transmit data over the same two power wires, allowing both weight reduction and cost reduction, due to harness design, assembly and integration tasks simplification.

The advantages:

  • Two front ends, for power sources and for consuming energy devices
  • No Power Distribution Unit (PDU), each device has its own power/load management
  • Smart Battery Management: on-board computer can decide which of the distributed batteries is active
  • MPBUS branches can be jettisoned (launchers stages)
  • Up to 3 Mbps per data comms









AZO: For those, who don’t know you yet – Tell us a bit about your company/project.

JMP was founded in 1992 by a team of professionals coming from the automotive industry and devoted to apply the most advanced technological solutions to the industrial sector. JMP is a SME officially certified as Private Research Center and located in the region of La Rioja (Spain). JMP is currently a multifunctional engineering company aiming to provide support and to contribute to those SMES that lack an R&D department, but need to develop new products or improve their manufacturing process through technology. Continuous investments on both technical equipment and qualified staff have provided our firm with the means to carry out worldwide projects in varied areas of leading-edge technology. Usually, we develop technology for strategic sectors, adapt and reuse that technology in basic industrial everyday sectors, but sometimes it is just the opposite case.


  • Highly motivated and experienced engineers.
  • Consolidated experience in industrial systems real implementations.
  • Dynamic response to evolving markets.
  • Reliable innovative solutions.
  • Fast direct complete attention to our clients.


  • ART.
  • PAPER.

The rapid growth of the private satellite launchers sector is leading the space race.

With the privatisation of the sector, all involved companies are racing for a more efficient and profitable way to bring satellites into orbit, bearing in mind the new industrial framework of the sector.

Now Volts, Amperes, Meters and Kilograms are immediately converted into money.

To achieve the profitable objective in terms of space, weight saving with reliability of more simple solutions is one of the best strategies, and this is one of the main results of the MPBUS project.

In spacecrafts, we can find devices that store and provide energy (e.g. batteries) and devices that consume energy (e.g. electronic, sensors, radios, etc…).

Traditional power distribution subsystems designed to connect all these devices, involve not only a big amount of power wires, but also much more wires for device data communications.

More wires implicate more weight and more complexity.

Frankly speaking, we need another solution for the future.

MPBUS represents a new architecture for power distribution in spacecrafts.

Of course, we cannot avoid the use of wires for powering devices.

For this reason MPBUS’ concept combines energy distribution and data communications functionalities between all devices in the same power wire.

To achieve this, we only need a small front-end circuit for the power sources and a different one for the rest of the devices.

MPBUS device connection scheme provides a clear, flexible and lighter layout:

  • Simple and distributed power bus with a big reduction of power harness
  • A multi power source with a smart management of energy transfers (several batteries with different natures connected in the same bus, and the possibility of the empty ones be jettisoned)
  • In addition, we have a bandwidth for data communications between all devices (up to 3 Mbits) without extra data harness

The actual development level of the project is Technology Readiness Level (TRL) 5 (demonstrator that simulates real Vega operation – components tested in space conditions at Liège Space Center).

Of course, MPBUS is a double use technology and can be developed regardless of International Traffic Arms Regulation (ITAR).

In this moment, some companies like Airbus – Safrane Launchers, Yuzhnoye and many more have a real interest in the results…

MPBUS means not only to reduce the cost per kilogram of the payload on each launch, but also to open a completely new range of possible missions with current or future next generation launch vehicles.

MPBUS’ work which developed into a 27 month project from the FP7 Space programme of the EU Commission, involving a consortium of four partners, three SMEs, JMP Ingenieros as Coordinator and Nájera Aerospace from Spain, Yamar from Israel and the Centre Spatial de Liège (CSL) from Belgium.

AZO: After the INNOspace Masters competition: What were the next big steps you have taken to bring your business to the next level?

We are speaking with ESA BIC in order to open a new company in the ESA BIC facilities and we are preparing a new proposal for the EU Framework Programme for Research and Innovation Horizon 2020 that will allow us to reach a higher TRL level for MPBUS.

And how did you benefit from working with the German Space Administration (operator), ESA BIC (challenge partner) and AZO (organiser)?

For us, it is very important to have specialists and advisors, such as the ones we meet in the INNOspace Awards Ceremony.

AZO: In your opinion, which technologies and trends will have the biggest impact on your industry within the next years?

We think that the future for smart factories in Europe will combine simpler manufacturing product solution designs, based on new technologies with sensitive and collaborative robots allowing humans and robots to share work tasks in the same physical space. Using all our experience in process and product design, we are working just now in several convergence processes, from traditional to smart factories and we combine new technologies for factory data harvest. The results allow us to re-design the process, using the ability and intuition of a human worker with the precision and the strength of a robot as a secure work space. Using some of our augmented reality and vision tools, we enable an easy dialog between humans and robots.

AZO: How will these trends in technologies affect your value proposition in the near future?

In the future, a simple and distributed power bus with a big reduction of power harness will be manufactured and installed by a team of one human and one robot in a more efficient, secure and profitable manner.

AZO: From your experience, do you have any advice for future participants?
