<p>You can use Blockstream satellite as part of a system to conduct transactions, but it can't send transactions on its own.
You can create the entire process of sending and receiving transactions (running a node), without a personal internet connection, by combining the Blockstream satellite hardware to receive blocks, offline wifi for local transactions, and localized mesh networks or SMS for broadcasting.
Excellent breakdown of process here:

Hello, @BTC_FTW, that's a nice link, but your post didn't answer the question of the asker, paraphrasing: Can you only receive or also send using the satellite? Any chance you could edit your answer to include an answer to that main question and perhaps a couple sentences of what was great about the linked article?

<p>No, communication is unidirectional, you can only receive the data which is broadcast by the system. The satellites <a href="https://en.wikipedia.org/wiki/Eutelsat_113_West_A" rel="noreferrer">being used</a> are TV relays, the uplink essentially being amplified and re-broadcast without any knowledge of the content.Transaction broadcast needs to happen by terrestrial services like a cellphone network, dialup modem, or just the regular internet. </p>

<p>Noob question here. Is it possible to send bitcoin transactions using Blockstream Satellite node or is it used only for receiving blocks?</p>

Not your question, but you **can** send bitcoin transactions via SMS.  This combined with the satellite download could build a bitcoin system for those without highspeed internet.
