Data from space, the libre way

SatNOGS is maintained by the Libre Space Foundation, a non-profit built to develop and promote open source space technologies and open access to space-related data. The passion we have for space and open source is what drives us, and we are proud of the community that has been built around SatNOGS. Over the past four years of development, the SatNOGS community has grown to more than 100 ground stations around the world with more than 2000 satellite observations per day.

On November 27th, Amazon announced the AWS Ground Station service. Like other companies who are currently operating ground stations as a service, this will allow satellite operators to receive their data using proprietary and closed-source technologies. The SatNOGS community is focused on building a ground station network that provides downlinked satellite data to researchers and operators worldwide, in an open way and free of charge. As we have for four years, SatNOGS will continue to serve organizations and missions that value the openness of science and data.

With Amazon and other companies entering this space, our vision for SatNOGS remains the same: to advance open technologies and open data for space by creating the best and largest open source satellite ground station network.

We will continue to develop in the open, and invite all space and satellite enthusiasts to join us!

SatNOGS #1 in Athens, Greece

10 days ago we deployed a SatNOGS v2 on top of hackerspace.gr in Athens, Greece. This is the first SatNOGS deployed on the field and we couldn’t help but thinking that this is a huge milestone and brings great pride to the team!

SatNOGS #1

(obviously the front cap is closed at the finished deployment)

The deployment was pretty straightforward, with one UHF helical antenna (our VHF is still up for matching) and no SatNOGS client controlling it (still under development for connection to Network). We simply controlled it with gPredict and Gqrx. POE for powering it up and minimal weather shielding (just some silicone on and around the bolts of the box)

We were able to track and record many different satellite passes and we encountered some software issues with our arduino homing code (see our post on community forum for details) which we hotfixed.

Congratulations to the whole SatNOGS team for the first deployment!
