@fredy and @elkos from the core team
Pierros here indeed :) Also
(apart from @cshields)
OK, great - hard to keep track sometimes. Welcome all! Can we start off with a little introduction on what SatNOGS is for those who don't know?
SatNOGS is an open source stack of technologies for tracking, communicating and gathering data about satellites
What is the technology behind ?
That includes Ground station designs, (antennas, rotators etc), Client software, Radio software, and then on the server side many applications to orchestrate this data gathering (network, db, dashboards and others)
So the intention is data sharing, and the hardware side is the enabler?
What is the motivation behind ?
with a goal of improving access to data coming from space (mostly in the ham radio bands)
@manaschhabra depends on the part of the stack ;) For client running the satellite observations locally it is C/GNuradio and Python, for server side it is mostly Django
how is the business sustained? like a charity?
How are users getting benefitted ?
And isn't it a niche area
@manaschhabra motivation is to have open data for everything space (check our foundation : Libre Space Foundation) and to promote usage of open source technologies in the space domain
Let me set a little background/context,
@Hexastorm Non profit foundation behind it (Libre Space Foundation), we do have grants for development and do provide services, also winning prizes (hackaday 2014) helped kickstart this!
typical satellite operators doing low-cost LEO (cubesats, etc) are often universities or research groups who may see their satellite overhead a couple of times a day. There's a lot of data they may miss out on inbetween. SatNOGS is building a global network of receivers (and the network software) to automate the collection of data for these satellites using SDR devices and raspberry pi, thus increasing the amount of data *collected* from these satellites
What about from "regular" satellites - images, datasets, etc?
we have hundreds of ground stations contributing now, and an automated path to go from RF to telemetry dashboards (dashboard.satnogs.org)
Would you say satnogs/libre space is at production state, or "beta", or well before that?
Is satnogs, rx only?
@ted I would say in production for most Telemetry oriented usages, and alpha on other.
@ted for Libre Space projects some are well in production (or proven in space) (check UPSat mission and others in https://libre.space )
@anfractuosity It's Network side yes. Locally client can TX as well. but we are trying to sort out the legal constrains around TX'ing though the Network
(It is a deliverable for us for an ESA project to do TX to, so it should be solved by end of 2020 any case ;) )
Is Satnogs in any way associated to AWS Ground Station?
consider it the "free tier", open source alternative ;)
@RichardCollins What do you mean by regular? NOAA, ISS METEOR etc... ?
there seems very little information on the hardware of the AWS ground station stuff
at least that i could find
AWS ground station is focused on their commercial...
