This marks the continuous efforts of hundreds of owners of SatNOGS ground-stations operating numerous ground-stations globally (more than 170 stations on-line, more than 90 in testing and more soon to come) while continuously enhancing the network software and hardware solutions.
LightSail2 solar-sail deployment
On our previous post we mentioned making a data dashboard based on data retrieved from LightSail2. Among this telemetry data are date stating the status of the solar sail on-obard LightSail2, the Planetary Society shares lots of info about this deployment.
The are lots of information on our wiki on how to create a decoder and how to make a telemetry dashboard while you can always get help from our active community forum. Since we mentioned LightSail2, the Planetary Society on the look-out (literally) for optical verification of its solar-sail deployment so don’t hesitate to look at the night skies.
The Space Library and SatNOGS
If you are following updates from the Libre Space Foundation’s websites work has started on the Space Library, a collaborative project of the Wolbach Library at the Center of Astrophysics | Harvard & Smithsonian and & the Libre Space Foundation funded my the Alfred P. Sloan Foundation.
The aim of the Space Library project is to assist new communities participate in satellite missions, engender public engagement in space science, and to fuel new research by improving access to scientific research artifacts and supporting their reuse.
Amongst its sub-projects will be MetaSat & LSTN. MetaSat will develop and prototype an open metadata schema to link data, software, and hardware from small-satellite missions. The schema will be designed with the small-satellite community and piloted on SatNOGS, LSTN (Library Space Technology Network), aims to engage novices, and for them to assess their capacity to use these technologies we are installing SatNOGS on public libraries.
SSTV (slow scan TV) events and automation
During the week of June-to-August Inter MAI and ARISS were transmitting SSTV images from the International Space Station. These images are uploaded on the network in most cases by a custom script but users are already implementing a GNU-radio out-of-tree module to facilitate the automatic decoding of such images in the future.
Dr Lucy Rogers write-up at RS-DesignSpark on building a SatNOGS station
Dr Lucy Rogers has set-up her own SatNOGS ground-station at her back garden inspired by Jo Hinchliffe’s article on a previous issue of Hackspace magazine, and she put together a great write-up on RS-DesignSpark documenting her installation.

A Busy Few Weeks for New Satellites, Observations and Dashboards!
Between Rocketlab’s “make it rain”, Space X’s Falcon Heavy and the Soyuz launches over the last few weeks we have seen a lot of new satellites launched. Our community has been really busy scheduling observations, helping identify objects from early TLE and, of course, returning data and creating dashboards for them. Notably it has been fantastic that the community have been able to hear and create a dashboard for the Planetary Society’s LightSail 2 mission and it’s fabulous we have had mentions and praise from their channels.
Finally to keep track of all this particular batch of launches and their status regarding SatNOGS observations/TLE/Dashboards and more check out the following two posts on the Libre Space Foundation Community forum.
LA1K SatNOGS Antenna Build
The amazing crew over at the Akademisk Radioklubb have been busy once again making more improvements to their SatNOGS station set up. Their latest blog has an update on their antenna builds. It’s great to see this thriving radio club’s activities and we are proud to have them on board!
Open Source Cubesat Workshop, Spread the word
We’ve talking a lot about OSCW on our social media channels this last week and its really exciting to see abstracts/submissions for talks start to arrive! We have (hopefully!) been reminding everyone why its an excellent idea (in our opinion) to come and join us at OSCW with some quotes from previous attendees like the one above from Daina Bouquin who is the Head Librarian at Center for Astrophysics. Harvard & Smithsonian. If you are working on something space related using open source methodologies we would love to hear from you and you can send the OSCW team an abstract via this link.
NepaliSat-1 received by Nepal SatNOGS ground station
The SatNOGS network is beginning to receive transmissions from some new satellites deployed from the International Space Station earlier this week. Amongst them it was wonderful to see our Nepali friends at Orion Space receive a signal from NepaliSat-1, Nepal’s first Satellite. The successful observation was received via their SatNOGS ground station. Orion Space use SatNOGS as a teaching tool in their programs that enable students in Nepal to have experiences of space related technologies. We are proud to be a part of their toolkit.
A Busy ARISS Week
It’s been a busy week for ARISS with June 19th seeing a contact between King Island District High School in Currie, TAS, Australia and Astronaut David St-Jacques. Then yesterday, June 20th, a contact between Rowan Preparatory School in Claygate, UK and astronaut Nick Hague.
Both ARISS contacts were observed by numerous SatNOGS ground stations and example observations can be found and listened too via these links.
LSF Team at Ham Radio Friedrickshafen
Finally a massive shout out to all the LSF crew who are attending Ham Radio Friedrichshafen. They are displaying and talking about the range of Libre Space projects including of course SatNOGS. If you are attending the event do go and chat to them and find out more about our activities and how you can get involved. They are at stand A1-562.
Observations of the ISS Spacewalk Captured
On the 29th May cosmonauts, Oleg Kononenko and Flight Alexey Ovchinin, undertook an EVA (spacewalk) outside the ISS to retrieve science experiments, install some new handrails and conduct some other routine maintenance. Numerous successful observations of the EVA were captured by ground stations on the network and you can listen to the EVA communications. This post on the Libre Space community forum has links to all the observations.
Antenna Types Comparison
SatNOGS legend Corey Shields has begun some comparative work on antennas. Corey is using the same location and the same observations to test directional ax/el yagi, a fixed low-gain yagi and finally a discone. It’s interesting work and Corey is posting his results and discussion here.

Links to posts on the libre space community forum for each of these ISS SSTV events can be found here;
A little late with this update but many SatNOGS contributors and team members made the trip to FOSDEM 2019 and got an opportunity to promote SatNOGS and also work together on various projects. A couple of posts on the Libre Space site and the SDR Makerspace site cover the trip and the varied events and activities well. Interest in SatNOGS was, as ever, high and we have seen people we talked to on the booth registering on the Libre Space forum which is great to see.
Akademisk Radioklubb Repair LA1NGS Ground Station
This week a story from Trondheim Norway. We love this story because it shows the fabulous co-operative nature of the SatNOGS community. Established in 1923 Akademisk Radioklubb is the oldest amateur radio group in Norway. The group has been using the LA1NGS SatNOGS station to schedule observations. Owned by NTNU Small Satellite Lab and Orbit NTNU they noticed that the rotator on LA1NGS had stopped working. Keen to help members of the Akademisk Radioklubb reached out and helped them replace the worn Yaesu G-5500 rotor with a new SPID SPX-02 . As reward they were given the G-5500 which they hope to refurbish and build their own station. More detail and lots of pictures on the Akademisk Radioklub blog.
Ground Station Hardware Report
Fabulous contributor Azisi has produced a useful report over on the Libre Space Foundation Community discussion forum. It collates the various hardware projects relating to creating ground station hardware and gives links to the repositories and to documentation. There is a real range of projects here from the rotator assembly through to small PCB notch filter to remove unwanted FM bands. Check out the post and get building here!
ARISS Contact Ashbury College Junior School, Ottawa Canada
Once again ground stations on the SatNOGS network captured a great ARISS conversation between a junior school and the international space station. For details of the contact and also to hear the observations themselves, be sure to check out the post on the Libre Space Foundation discussion forum.
Over 300 data contributors to SatNOGS Database
That’s right! Over 300 stations are now supplying data to the SatNOGS database. This group comprises of the ground stations on the SatNOGS network and also those stations that chose to add data manually. Huge thanks to everyone in the community working hard to achieve this. For statistics about the SatNOGS database visit this page.
Dashboard Development Continues
The team have been working hard to refine and redevelop the SatNOGS dashboard project. Major changes have taken place and with that, you may have noticed some satellites and dashboards not currently updating. To help follow progress, there’s a dashboard that shows daily decoded frames per satellite here. To follow updates and discussion on the dashboard project check out this thread on the Libre Space community page.
SatNOGS Demo Display from 35c3
Fabulous community member ar3itrary set up a great SatNOGS demo display at 35c3. A python script rendering the waterfall of the latest SatNOGS observation, to a nice info graphic is set to update every minute as a cron job. The python script is available here.
