SatNOGS Activity Update 2019-06-03

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.

SatNOGS articles in Hackspace Magazine

This months Hackspace Magazine has a large feature around space and makers. The article features SatNOGS Libre Space, UPsat and much more. There is a complete tutorial on how to set up a ground station and even a short tutorial on a DIY Slim Jim antenna. Hackspace magazine is part of the Raspberry Pi group and as such the SatNOGS tutorial was reproduced on the main Raspberry Pi site. The issue is available to order a print copy or to download a free PDF via this page.

French Language SatNOGS Presentation

SatNOGS community member Jujun has delivered a talk to the ADRI 38 audience about SatNOGS. Whilst my french is not strong, it’s apparent from the video he gives lots of detail about different types of SatNOGS ground station setups and presents lots of antenna ideas. Many thanks Jujun.

SatNOGS at Hamvention and Other Upcoming Events

Very pleased that SatNOGS will be represented at Hamvention 2019 which takes place between May 17th-19th in Ohio, USA. If you are attending do make sure to come and see us at booth 1006. We have a lot of events globally coming up with a SatNOGS or Libre Space presence and a full list can be found on this post over on the Libre Space Page.

SatNOGS Community Help Kicksat Mission

Our fabulous community and in particular Cees Bassa helped out Zac Manchester in tracking down his Sprite satellites (a single PCB satellite that is around 35mm x 35mm) after they were deployed in a low earth orbit from the Kicksat2 cubesat mothership. Cees has been working on the Dwingeloo radio observatory and used this large dish to help track down these tiny craft. Exciting stuff.

Akademisk Radioklubb LA1K Station now online!

sdr

Our friends at the Akademisk RadioKlubb in Norway (who have been featured before here having helped a neighbouring station replace a rotator) have been busy and have commissioned another station. Named LA1K (which is the oldest operating call sign in Norway) we look forward to seeing lots of successful observations being returned by this great installation.

MySat-1 First Received On SatNOGS network

Excellent work by Mark Jessop scheduling this observation resulted in the first results from the MYSAT-1 via station 232 on this observation. He passed the observation back to MYSAT-1 via their twitter feed and they were thrilled to say he was the first to hear and expressed their thanks.

Dashboard for MYSAT-1

Following on from the above story our fabulous contributor Patrick DL4DP has put together a dashboard for the MYSAT-1 mission which is publicly available here

Decoding eshail 2 go using gr-satellites

Its been a busy week for Patrick! He has also put together this great tutorial post on how he has used gr-satellites to decode the BSPK 400bps beacon on the EsHail-2 QO-100 transponder based on some ideas he had seen from Dani EA4GPZ. Check out this post here on the libre space community forum.

FOSDEM 2019

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.

SatNOGS Activity Update 2019-01-27

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.

SatNOGS Activity Update 2019-01-05

SatNOGS Dashboard

The SatNOGS dashboard is now live! Decoded telemetry data from SatNOGS db is pulled into a new database built using influxdb, in turn Grafana is then deployed to visualise the data. This tool will be useful for mission monitoring and also for outreach events. Documentation about the dashboard is available here.

GNU Radio Conference 2018 Keynote Uploaded

Videos from last years GNU Radio Convention 2018 (GRcon18) have now been published. Manolis did an excellent job delivering the keynote focusing on SatNOGS, whilst also covering wider aspects of the Libre Space Foundation. Check out the video above.

AutoScheduling

Over on the SatNOGS section of the Libre Space Foundation Forum there is activity and discussion around the development of an auto scheduling tool for stations. To facilitate the upcoming needs of the auto-scheduler some small updates have been pushed to the Network API and the SatNOGS database . Follow the progress and discussion on the forum here.

SatNOGS Activity Update 2018-12-20

db.satnogs.org migration

So this week the team migrated the SatNOGS database to its new platform. This operation was crucial and ensures that we have a stable and well scalable database. Whilst the total data held on the database might not be huge, it contains a very large number of files.  Overall, the migration went well and downtime was kept to a minimum.  We would like to thank the team for their hard work making this a flawless process. 

How to Schedule an Observation blogpost

This week a blog appeared with a walk through of screenshots explaining how a ground station owner schedules observations on the SatNOGS network. This aspect of the SatNOGS network is accessible only once someone has a station set up therefore it’s helpful  to show people  how easy they are to use once they do! Check out the blog here. 

ARISS Contact Kenilworth, UK

On the 14th December many SatNOGS stations were able to hear an ARISS contact scheduled between Kenilworth School and Sixth form College and the International Space Station. The scheduled astronaut was Serena Aunon-Chancellor KG5TMT. As usual, you can find the list of successful observations and can listen to them via this post on the Libre Space Community page.

 Single Sign On for all Sites, Auth0.

This week members of the team made changes enabling us to have a single user database across our websites. This means users can log in to one site in the ecosystem and authenticate across the rest with just one-click. This now applies to community.libre.spacenetwork.satnogs.orgdb.satnogs.org, network-dev.satnogs.orgdb-dev.satnogs.org, and dashboard-dev.satnogs.org.  As a result, there’s no more need to create individual accounts across those 6 sites, one account now works on all! In conclusion, massive thanks and respect to Auth0 who provide this as a service through their Open Source program.

Rocketlab Electron Curie Launch and Hunting Satellites!

This week Rocketlab successfully launched their Electron ELaNA-19 mission succefully and deployed some satellites to orbit. As with every new launch, the SatNOGS team and community have been trying to hunt the satellites. Currently 5 satellites TLE’s and information have been made available and one satellite has been heard! Additionally, track the development of this over at this post on the Libre Space community page.

SatNOGS Weekly Activity 11.12.18

Networked to History!

This week the Dwingelooradio Observatory tested their 25 meter dish as a SatNOGS station! Although not set up as a permanent SatNOGS station it is great to see this historic observatory linked to the network. Dwingeloo radio observatory was built between 1954 and 1956 near the village of Dwingeloo in the Netherlands. Since 2009 this single 25 meter dish has been a national heritage site. 

New Station on Crete

Also this week, To Labaki Hackspace and the University of Crete have joined forces and have set up a SatNOGS station in Crete. With some support from the Libre Space Foundation, we welcome them to the network!

Weekly Meetings Re-established

This week we resumed the SatNOGS weekly update meeting on the IRC channel. There was a lot of activity and discussion with a large group of attendees. The meetings are planned for Thursdays at 18:00 UTC on the #satnogs channel @FreeNode IRC network which is also available via riot.im. Keep an eye on the SatNOGS section of the Libre Space Foundation forum for agenda details. It will routinely include news, updates, status of projects and discussion of outstanding issues.

As ever, it’s inspiring to see everyone working hard not just on these stations and meetings, but all over the network. Keeping us on track and helping us democratise space the libre way. 

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!
