Introducing the brand new SatNOGS DB!

Quetzal-1 Information

Today, we are thrilled to announce the launching of the newly-redesigned and updated SatNOGS DB. We have put a lot of hard work into it and we are thrilled to present it to you.

A New UI for SatNOGS DB

The brand new SatNOGS DB focuses on providing an improved experience to users. It has a clearer and more efficient design, a more user-friendly interface and a more efficient and functional DB.

To start with, the design of the welcoming page has changed featuring three main fields. The first field is the New Satellites field. It contains the names of the latest satellite entries. The second field is the Latest Data and lists the names of the satellites receiving the latest data. The third field is the Recent Contributors field. It features the long list of the names of the contributors collecting data in the last 24 hours. Perched next to the names is the number of data frames they have contributed to the SatNOGS DB.

Old SatNOGS DB

As with the old DB, the new SatNOGS DB sports an “All Satellites” tab from which you can navigate and scroll through the long list of satellites (400+) tracked by the network. A new feature added is the ability to see the status of a satellite. What is more, there is a recently-added “All Transmitters” tab listing all the transmitters (900+) in the network. This is a separate and distinct tab, under the “All Satellites” tab on the left of the screen.

For each satellite, there are dedicated views with additional information for the mission and its operational status.

There is also a Statistics tab. By clicking on it you can land on a page offering you a more spherical view of the numbers making up SatNOGS. Indicating the number of satellites, transmitters, data frames, frequency bands and modes of transmission.

From a technical point of view, the DB is built based on the Django Python framework. You can find the code here and if you have any suggestions or ideas on how we can further improve SatNOGS DB feel free to create an issue! We would love to read your suggestions!

The work of SatNOGS DB redesign was headed by our core contributor Corey Shields, with additional work from Julien Flawinne and Pierros Papadeas.

Future Work

SatNOGS DB has exciting new things in the pipeline, which are currently under development. Integration with Metasat Schema, Orbital Data tab per satellite with extended view and analysis, more satellite attributes and information, additional artifacts from observations, are just some of the new features coming soon!

About the SatNOGS DB

SatNOGS DB is an integral part of the SatNOGS project counting over 360+ satellite ground stations worldwide. It is an open-source, participatory initiative, fueled by the contributions and efforts of its devoted and diverse community of space enthusiasts, radio amateurs and satellite observers. SatNOGS DB is an attempt to create and maintain an up-to-date global Database of all artificial objects in space (of satellites and spacecrafts too). It is machine-readable and open to everyone who needs to have access to the data obtained. You can even connect your application to it using the available API.

This crowd-sourced, open-development and fully-transparent approach we apply to the SatNOGS project is a great example of how we operate and manage projects at the Libre Space Foundation. Everything we do adheres to the beliefs and the principles fueled by the Libre Space Manifesto. You can find out more about the Libre Space Manifesto and its principles and you can even show your support if you agree with it.

Care to join us?

If you have been intrigued by what you have read so far, have in mind that you can always join the SatNOGS project. Whether you are a space enthusiast wishing to build a SatNOGS ground station or you are fluent in Python and/or JS and you wish to contribute to the SaNOGS-DB web application. Everyone is welcome and you can start by reading how you can Get started with SatNOGS. You are also more than welcome to join our community forums and our riot/matrix channels. Reach out to us and be part of our community. We would love to hear from you!

Reaching a new Milestone: Celebrating the 2,000,000th SatNOGS Observation!

We are excited and thrilled to announce that the SatNOGS network has reached its 2.000.000th observation on the 9th of April!

Observation #2000000 got uploaded on the SatNOGS Network by station #6-Apomahon in Nea Filadelfia , Athens, Greece, operated by Dimitris Papadeas receiving data from SOKRAT satellite.

The 2.000.000th observation is a result of an amazing network of ground stations and it marks the continuous efforts of hundreds of ground station owners! The SatNOGS community boasts a booming number of 200+ fully operational ground stations and 100+ in testing mode. The observations come from 400+ satellites and 880+ transmitters and over 64.800.000 data frames.

Do you want to join the next millions of observations? Do you want to be part of this community? Check out the SatNOGS knowledge-base wiki, and don’t hesitate to reach out to the community forums and chat. We would love to have you onboard the SatNOGS network and community. Join us now

SatNOGS client March 2020 update

The time has come for a brand new update! We would like to announce that a new upgrade is available for the SatNOGS Client software. You are advised to check the SatNOGS Client Setup wiki page to find out more about how to upgrade and configure your station.

A few words on the new update

You will find that in the new version, Ansible has been updated to include all the latest stable SatNOGS Client, Radio and Setup Software. This new version sees a major shift towards new technologies and new architecture.

Advanced Configuration Settings

One of the most significant changes that this new release delivers is gr-soapy and the transition from the OsmoSDR library to the SoapySDR Library. This inclusion brings forth numerous performance improvements and expands support to include new, upcoming software-defined radio devices. As far as gr-soapy is concerned, it is a sub-activity of SDR Makerspace; an initiative brought on by ESA and Libre Space Foundation. The aim of this initiative is to develop several open-source, Software Defined Radio projects to enable, facilitate and support satellite communications. The latest SatNOGS update delivers to you this technology.

What is more, this new release comes with more sensitive decoders allowing a wider range of data to be collected by the network. With each satellite pass, more valuable data is collected, enhancing observation results. Note that contributions have been made easier as the GNU Radio flowgraphs have been removed from gr-satnogs and have been granted a separate, dedicated repository satnogs-flowgraphs.  Lastly, satnogs-config, the SatNOGS client configuration utility, has been rewritten in Python allowing for rapid development of new configuration features.

SatNOGS

SatNOGS constitutes an amazing open-sourced project comprised of a global network of satellite ground stations. It is a participatory project which allows for satellite information and data to be available to any observer and enthusiast. Not only can individuals utilize all available ground stations, as they have free access to those, but they can even communicate with the satellites. The data and the results of the observations carried out are distributed freely.

This aligns with our values as they are expressed in detail, in the Libre Space Manifesto. We firmly believe in the power of information and how it can drastically contribute to allowing humanity to explore new horizons. Free access to information can help develop and use knowledge differently, and even thrive in different ways while overall changing life for the better.  For this, we work hard towards expanding the network of ground stations as well as providing updates (like the one we released) for the SatNOGS software. We wish this project to run on the most up-to-date technology and architecture, offering improvements and making observations more accurate and efficient.

The latest update facilitates improvements in performance, technology, and architecture for a network of 200+ fully operational ground stations and 100+ in testing mode. These have delivered over 1.900.000 observations (and counting), from 400+ satellites and 880+ transmitters and over 64.800.000 data frames. With the latest release, we aim at improving this whole network of free information and knowledge and making it more accurate for the observer.
