DOCKS is a C²ERES endeavour to provide everybody with free tools for mission design, in Earth vicinity or in deep space. Modules in DOCKS include:
- A carefully validated Deep-Space propagator with enough flexibility to simulate cruise trajectories or proximity operations at a non-sphérical asteroid; for Earth vicinity, user-friendly interfaces to STELA, free software by the French agency...
Classical way of calculating link budgets consists of considering static values of every parameter taken at their worst-case scenarios. This usually provides a good overview for mission analysis, sizing of the communication sub-system and preliminary link design. However, considering geometry, the worst-case scenario mainly concerns station visibility windows limits when the Free Space...
Software-defined radios (SDR) have become an integral part of many CubeSat missions. The availability of low cost, high-performance SDR hardware enables cost-effective solutions to complex telecommunication tasks, including unattended, interactive, and remote operations.
In this presentation, we take a look at recent developments in open-source SDR applications and demonstrate how they can be...
More than 60 years after the first orbiting human-made space object (1957), we’ve reached about 1800 satellites in Earth orbit (2018). They are currently operated by private corporations, governmental and multi-governmental space agencies. They orbit along with about 2600 other satellites, whether decommissioned, retired or non-functioning.
The recent trends in New Space involve space...
The SatNOGS network is a global network of open-source ground stations that allows users to track, monitor, receive telemetry, and command satellites without the need to build their own network of stations. This helps to reduce the costs and complexity of operating and communicating with a spacecraft, which is especially important for CubeSat missions which are usually run by small teams with...
The SDR Makerspace is an initiative of European Space Agency (ESA), implemented by
Libre Space Foundation (LSF). The goal of this program is to bring together makers,
open-source hackers, radio amateurs, and a passionate community for dealing with
challenges related with Software Defined Radios in space communications. This activity
consists from several sub-activities, covering a wide range...
Whilst there are examples in many software and some hardware business of the commercial success and sustainability of the open source approach, the philosophy is still very much in its infancy in the space domain.
The few examples of open source missions have been limited to very small satellites (PocketQubes and Cubesats), with a primary focus on technology demonstration within the academic...
Despite efforts, large quantities of space debris end up in various orbits threatening, not only current and future missions, but also space exploration as a whole. The addition of mega constellations will most likely only worsen the probability of collisions and visual exploration. Added to this, there is the fast-growing telecommunications industry, and with cube-sats becoming more in...
MetaSat, an open metadata schema in development, will function as a common way of describing hardware, software, and data across small satellite missions to improve interoperability between them. This new digital infrastructure will help missions learn from each other now, and help people share information about past missions with future generations.
Capturing the breadth of work being done...
The control and monitoring bus is the backbone for routing commands and telemetry among spacecraft subsystems. Typically, a central processing unit is commanding other intelligent nodes (such as the power system, communication system, and payloads) and collects status information from them. The data to be exchanged on this bus is of moderate volume but must be transmitted in a reliable...
In order to track a satellite you need to know its orbit. In most cases orbit is described by TLE (Two Line Elements) set which is a data format encoding a list of orbital elements. The main source of TLE sets for objects orbiting Earth is the United States Space Command (USSPACECOM) through the space-track.org website.
Soon after satellites deployment, tracked objects show up in...
In this work we present a Multiple Input Multiple Output (MIMO) Ground Station comprising of multiple Software Defined Radio devices (SDRs) and uses a novel approach to time-synchronize them. The array employs four receiving antennas and one transmit antenna which is used for device synchronization using the long training sequence of the IEEE 802.11 protocol. The antennas are mounted on four...
An overview of the SatNOGS project, a network of satellite ground stations around the world, optimized for modularity, built from readily available and affordable tools and resources.
Low Earth Orbit (LEO) satellite launches rate increases with the participation of old and new entities. In this growing environment SatNOGS provides a scalable and modular solution to track, receive telemetry,...
LibreCube – Open Source Space and Earth Exploration
LibreCube's vision is to enable everyone to get involved in building systems for exploration of near and remote locations using open source hardware and software. We believe that discovering new worlds and getting scientific insights should be a matter to all humankind.
This presentation reviews the various activities conducted in 2019....
We have initiated the development of a flexible, fully Open Source, flexible microsatellite platform, embracing an open source approach, to create an efficient fail-safe microsatellite platform that is performant, capable, modular and robust.
The platform can be readily tailored for different missions, can be upgraded and configured after launch and can operate with multiple ground station...

The FORESAIL project is a scientific Cubesat-satellite project by the Finnish Centre of Excellence in Research of Sustainable Space. The project is funded by the Academy of Finland and it focuses on research of the solar wind interactions in the Earth’s magnetosphere in high temporal resolution [1] and investigates new sustainable methods for space technology and research. The project aims to...
Plans for the return of humans to the Moon and the imminent manned exploration of Mars drive an increased need for research in the fields of space physiology and biology. This need can be fulfilled with low cost solutions such as CubeSats, by obtaining results from experiments which were previously possible only on crewed spacecraft such as the International Space Station and required...
Free-space optical communications for CubeSats
Abstract
The TeideSat project was born as an initiative of students from the University of La Laguna with the desire to know more about satellites and space, which led to constitute a team whose objective is the design, construction, placement in orbit and operation of a nanosatellite based on the CubeSat ESA standard.
It is the first...
Libre Space Foundation in collaboration with ESA is developing a novel versatile Cubesat communication system. The product will support UHF and S-band frequency configurations and shall be part of an end to end (E2E) turnkey solution for satellite communications. The proposed solution covers the CubeSat onboard transceiver, the ground segment for Command and Control as well as analysis of the...
Do you need to create a link budget? If so, chances are high you download Jan King's Excel spreadsheet, fill in your numbers, and take the result from there.
But that is a cumbersome, manual process that only outputs one result per case.
Now there is LinkPredict!
LinkPredict is a Python3 library for defining radio links in a generic and modular way and provides time-dependent outputs of the...

A round table discussion on the future of Open Source Cubesat Workshop, its audience, possible directions, broader ecosystem and format considerations.
In this presentation, an overview and update of a compact laser setup for generating Single Event Effects (SEE) of cosmic radiation is presented. After my talk at OSCW'17, many new features were developed and will be addressed. Especially the Laser-Scanning-Microscope functionality opens the door for generating SEE with a known absolute position on the chip. The attached pictures show a...
