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.

As mentioned the community has been busy and numerous new dashboard are appearing including Lightsail 2 (above) and ACRUX-1 (below) and many more. Check out all our available dashboards here.

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.

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.
