New users welcome

Hi folks, my name is John and I’m looking to get back into ham radio and this seems like it might be a good fit for my interests. Looking forward to learning more!

Hello everyone,
I am Jayant Bhakar, a lover of space science. I was glad seeing this project and would love to contribute the best I can.

Hi

I am Graham G4NMD and just getting into rpi and satellites. Finding it a steep learning curve and trying to work out why my rpi and satnogs only briefly shows up on the dashboard and then reverts to setup mode.

Hey @driscollta @g4nmd @jayant @johnedens @sathisbdst welcome to the community. Do look in on the riot/IRC groups as well.

Hi, I am Mir H. S. Quadri and I am a new member of the Libre Space community. I am a software engineer, currently in the process of getting a master’s degree in Artificial Intelligence. I came across the Libre Space Foundation as I was scrolling through the GSoC 2019 archives. I found the mission and the projects of this organisation very compelling and instantly wanted to contribute. Space research has always been extremely fascinating to me and I am super excited to get started here.

I had some project proposals in mind for GSoC 2020 and wanted to know if Libre Space is planning to participate in GSoC 2020? Can someone please confirm this for me?

Much Thanks!

So, we do plan on participating in this year’s GSoC and applied to do so. As soon as we get news about the status of our application we will be updating the relevant forum post.

Here is a primer on participating on GSoC 2020 with Libre Space Foundation.

All are welcome to dive in our source code, this community forum and our chat-rooms to get a feel of what we do. You don’t have to be a participant on GSoC to contribute on our source code so feel free to start right away.

Hej all,

finally time i introduce myself. Already heard about SatNOGS before but first really discovered it last December at SDRMaker in Payerne, Switzerland, where 2 people from SatNOGS had a stand.

Quickly set up an initial base station (#1207) in test mode with a rtl-sdr dongle and a RPi3 that was lying around with a small dual band magmount antenna. That was already enough to see some weak signals.

In the meantime i upgraded the station to

  • Stanislav Palo crossed UHF dipole
  • Nooelec LaNA LNA
  • Nooelec NESDR SMArTee v2 SDR

currently the antenna is still badly placed on the balcony. Living in a 1st floor flat with balcony in a houlse with several floors it is not easy to have a decent antenna placement but i’ll try to improve it. Currently mostly West opening (with some low houses in front), should be able to get South + West opening.
The other planned improvement is to put the LNA, Tuner and Raspberry in a metal box outside on the balcony close to the antenna.

I hope with a better antenna placement i’ll be able not only to see weak signals, but also to decode some telemetry.

For the rest i am a software engineer, mostly C++, but i don’t mind doing Python so i might take some looks around some SatNOGS code when i have some time.

I would be keeping the Raspberry Pi away from the antenna. They are noisy little buggers. Put it in a metal box. Some switched mode 5V power-supplies can produce a lot of noise too. USB cables radiate noise too. Clip on ferrite cores can help there. Put the LNA close to the antenna. I have been experimenting for a while and found the antenna is everything and I finally settled on a home made QFH antenna. (Google it)

Yes, doing QRP QRSS reception with raspberries ans rtl sdr dongles i learnt that the raspberries and the usb cables are transmitters and antennas on their own and there are definitively 50Hz intermodulations coming from cheap power supplies. So a correct power supply will also be part of the setup.
Maybe i’ll put the raspberry out of the case. But in any case it will have its own shielded metal box even if inside a bigger metal box.

Go space fans! Good luck to all ground station builders.

Hi all. I’m from Open Lunar Foundation. Unfortunately, we’re still in stealth, so I’m a bit limited about what I can say, but you can probably glean a bit about us from looking at our website and Googling some.

I’m also formerly the org admin for SciRuby as a GSoC participant org, and I’ve mentored GSoC for multiple years.

OLF applied but didn’t get into GSoC this year. We have a bunch of projects and mentors, however, and I wondered if we might join forces with Libre Space for some of these. It seems like we have a lot in common.

Anyway, hi! And glad to be here.

Pardon my stupid question, but I see a glaring conflict with your opening statement. I went to Open Lunar Foundation and can find no information. Is this an “open” foundation?

We’re a 501c(3) public charity. I’m not quite sure I understand the conflict.

If OLF is an “open” foundation, why can you not tell us of the work you are doing?

Hi @autumnsault

you can an add idea for GSOC 2020 of LSF with opening a new issue here. Please in the new issue choose the “Idea” template.

In the issue tracker there are some old and new ideas, and especially for GSOC 2020 there are some more info in this link.

cc’ing @elkos just in case he wants to add anything more.

@autumnsault Hi JW, welcome, don’t hesitate to share the projects you work and their repositories

I do think that @K3RLD 's point is that it would be extra helpful for the open-source community if OLF had more info about their projects, links to repositories, and bylaws available.
There are several ways people describe openness in a technological context. I would say that the minimum would be that the software created would be compliant with Open Source Initiative’s Open Source Definition and open-hardware (the TAPR and CERN OHL are pretty good examples on that).
To further elaborate on openness, I believe the Libre Space Manifesto would be a sound basis for any open space technologies organization to undersign.

As for GSoC, as @fredy said, the process described here would allow the community to discuss the further technical details of each idea.

We are compliant with OSI’s open source definition. I will investigate about the open-hardware standards (I’m not a hardware person), and where our bylaws can be obtained.

We do have a github: http://github.com/openlunar/

We also have our own ideas page here: https://github.com/openlunar/gsoc/wiki/GSoC-ideas

I’ll start working on getting these into your process. Things are a bit delayed here in SF due to COVID-19.

I can recommend the article “On Creative Commons and Open Source” by the Open Source Hardware Alliance (OSHWA).

edit: The following section handles about the OpenLuna Foundation, Inc. (A) not Open Lunar Foundation (B).
It also explains why the license under which you published your latest blog post, where you wrote:
> please respect our Open Source Creative Commons license. That is one of our founding principles: https://creativecommons.org/licenses/by-nc-sa/3.0/

, is not OSI-compliant.

CC-BY-NC-SA 3.0, your “founding principles” (according to the blog post), is not OSI-compliant. It directly breaks with the 6th OSD-criterion:

  1. No Discrimination Against Fields of Endeavor
    The license must not restrict anyone from making use of the program in a specific field of endeavor. For example, it may not restrict the program from being used in a business, or from being used for genetic research.

I’m very happy to see that the four projects with OpenLunar copyright in your github org, openlunar/trajectory (BSD-3-Clause), openlunar/orbdet (Apache-2.0), openlunar/nav (BSD-3-Clause) and openlunar/lincov (BSD-3-Clause), are published under OSI-compliant licenses though.

Welcome, and thanks for reaching out! :full_moon: :rocket: :tada:

Ah, thanks so much for bringing this up, and for the feedback. I’ll take this back to the team and discuss it with them.

I’m not actually seeing this anywhere on our website. Are you sure you aren’t looking at OpenLuna instead?
