SatNOGS-Client development team member Vasillis, using PiGen and Gitlab CI, created a SatNOGS Client Raspbian image to use with your Raspberry Pi 3 for your SatNOGS ground-station. To install and setup the image you can follow the Raspbian sector in the Raspberry Pi 3 SatNOGS wiki page. Following the instructions will get you to the SatNOGS Client configuration screen, from there you can add your ground-station’s details via the basic setup.
If you already created a ground-station in the SatNOGS Network website (or it’s stage environment) you should provide the relevant data for your Raspberry Pi and soon you will see your ground-station on-line.
If you haven’t created a ground-station in the SatNOGS Network yet, you can create an account in the SatNOGS Network stage environment, and create a new ground station (Note: as soon as you are satisfied with your ground-station’s performance you will be able to migrate to the production instance of the SatNOGS Network).
If you don’t have a ground-station you can either start building a SatNOGS Rotator, buy a commercial rotator using a commercial controller or even our ardushield, or simply use a no-rotator setup using a turnstile antenna, an LNA, an RTL-SDR, and your RaspberryPi 3 which is ideal as an introduction to SatNOGS and satellite hunting!
Since SatNOGS is not only a set of open source technologies but also a community effort don’t hesitate to reach out to the community, and our active channels IRC #satnogs at the Freenode server or the SatNOGS Matrix channel reachable by riot.im (both channels are bridged and riot keeps an archive of previous messages).
SatNOGS community has been busy over the last couple of months, with many exciting updates on projects to share with you!
First and foremost, the 3.1 version of the SatNOGS rotator is soon to be finalized. If you are already working with a v3 keep in mind that upgrading to 3.1 is pretty straightforward, on the meantime feel free to share your build progress or finished ground stations with our community We got have some stickers to send to SatNOGS ground station operators. We really hope that lot’s of people get to install their own v3.1 rotator and hook up to the SatNOGS network, and we are working on a way to get the v3.1 rotator design to as many people as possible.
Our crowd-sourced satellite database, SatNOGS DB, is expanding and will soon be powering Csete’s gpredict through it’s API. In the meantime we deployed new functionality that allows SatNOGS DB to visualize telemetry data captured using the SatNOGS Network of ground stations.
We really appreciate people participating in the SatNOGS project, either in our community website, our IRC/Matrix chatroom, the SatNOGS Wiki, populating the SatNOGS database and our source code repositories but we also enjoy meeting people interested in SatNOGS in person.
Last week on Linux.conf.au taking place in Hobart,Australia, Scott Bragg’s gave a great talk titled “Decoding Satellites With SatNOGS“. It was a great overview of the SatNOGS project and the ways you can get involved.
Since most of the core SatNOGS team lives in Europe most of us will attend FOSDEM in Brussels,Belgium this February. There Manolis Surligas is giving a talk “SDR for Space the Open Way” focusing on the Software Defined Radio RF frontend and the GNU Radio module operating it and will be introduced in the coming versions of the SatNOGS client.
Stay tuned for more detailed updates, and as always … keep hunting satellites!
Although quite some time has passed since our last update the SatNOGS team and the community was busy working on it’s software and hardware components allowing modular setups.
A large amount of focus has being the SatNOGS client software. Allowing the user to not only use RTL-SDR based dongles but a far greater variety of SDR solutions using GnuRadio. In conjunction with that SatNOGS client is able to use Amateur Radios that are supported by hamlib (we’ve already tested on Yaesu and Kenwood radios). Such functionality paired with our new ground station hardware design, and further tests on after market designs such us Yaesu Az/El rotator would allow the SatNOGS network to not only receive but transmit data via the network to satellites.
Since a few months now Libre Space Foundation, the organization that assists the development, and operation of the SatNOGS networks is has being working together with the University of Patras on developing and manufacturing the first satellite with most of it’s components based open hardware and using free software, UPSat.
An open hardware and software satellite especially one build by Libre Space Foundation would be a great chance for the SatNOGS network to implement command and control features on it’s SatNOGS client, allowing a fully open Low Earth Orbiting satellite communication stack from earth to orbit and back.
Communications with the satellite are implemented through ECSS Standard Commands as described in ECSS-E-70-41A standard (CCSDS). You can checkout the code of the client on GitHub and the ecss services implemented on the satellite here. There has been a lot of effort to make sure that we implement all needed functionality on the SatNOGS client, while in parallel maintaining modularity and extensibility for future satellites and other protocols.
Do you have a satellite in the works and want to use SatNOGS client as command and control? Let us know and we will be happy to work with you expanding our client!
Emilio Martínez is a Spanish Telecommunication Engineering (MSc) student at
University of Granada. He defines himself as an enthusiast of space-related technology and he would like to focus his professional career on the space industry when he finishes his studies.
He is enrolled in an aerospace developing group at University of Granada called GranaSAT. This group isformed by students and professors with the goal of designing and developing a Cubesat mission. Currently, Emilio is developing his master’s thesis about the Communications System of the Granasat Cubesat and the satellite-earth link: designing the Cubesat communication hardware, defining the link budget and improving their ground station capabilities in order to reach a reliable communication.
The SatNOGS team is looking forward for the expertise and know-how Emilio brings to our project.
We welcome all contributors that would like to be involved in the SatNOGS project and we would like to encourage all parties interested in satellite communications to join our community of developers.
Since the conception of the SatNOGS one of our design mantras was modularity, not only we believe that the SatNOGS stack should be able use a wide variety of components but also that components should be able to used in a wide variety of applications.
This Sunday May 1oth 2015 the SatNOGS team had the chance to test how versatile our SatNOGS rotator and control software was by tracking the Aeolus-2way High Altitude Balloon.
Tracking was made possible by receiving APRS data from the Aeolus-2way High Altitude Balloon and converting them using a specialized script as azimuth and elevation coordinates.
The balloon launched from the center of the Peloponisos peninsula of Greece in the city of Megalopolis at Plaka airstrip at around 11:10.
The SatNOGS team was positioned 35 km (~21.7 miles) West – NorthWest of the launch site on the Antenna park near the Ano Dolianna village of Mt Parnon. An inverter was used to power two laptops sever ham radio transceivers and our SatNOGS rotator and provide sufficient power for the team’s needs
The balloon began it’s descent at 34.660 meters and it’s payload was successfully retrieved.
We would like to congratulate and thank all parties involved in this high altitude balloon launch for the great team work and cooperation and especially the Aeolus team for their commitment.
ESA’s Summer Of Code In Space (also known as SOCIS) is an open source development program specifically for students run by the European Space Agency Under this program. ESA funds students to write space-related code for open source projects during the northern hemisphere’s summer.
Having access to an awesome 3D printer is certainly crucial for the SatNOGS project but the SatNOGS hardware is much more than 3D printed parts. To push the development of the ground station forward the core development team decided to acquire an oscilloscope, a programmable power supply and a Vector Network Analyzer
Following our ideal of sharing resources with the community, sharing it with the local hackerspace, we decided to install our instruments to it’s lab and share them with anyone interested.
In the future we plan to include to our instruments among other things a frequency generator and a signal analyzer.
We consider having access to a complete electromechanical lab/workspace is crucial not only for SatNOGS but for any community driven open hardware initiative.
To cover our needs we communicated with AlephObject in order to purchase a LulzBot TAZ4 3D printer. LulzBot didn’t only provided us with a superb open hardware 3D printer as usual but also they donated it to the SatNOGS project!
We are really excited by their offer, and stay true to the spirit of sharing that characterizes our project from the very beginning we decided to share our new 3D printer with the awesome community of the local hackerspace of Athens Greece a physical space dedicated to open hardware and software hacking.
To celebrate the occasion members of our team and the local hackerspace gave a welcoming event, and our 3D printing expert showcased TAZ4 and it’s awesome capabilities. He gave a hands-on introduction in 3D printing in general, TAZ4 and PrintRun (the free -as in freedom- software controlling LulzBot). Members and visitors of the hackerspace had the chance to print their own stuff (from Rocktopus figures to OpenBCI electrodes).
