FAQs: How long does a cubesat stay up there? How long is a single cubesat reachable during an orbit?
With COTS parts, operational life is predicted at 2-3 years, possibly years longer.

I'd like an interactive screen saver... click on a satellite and watch it go round and round.
The satellites can communicate with each other (P2P!). There will be multiple ground stations in multiple countries around the world.
That's the answer I was hoping for. So if the entire planet goes dark, the blockchain is swirling around us and continuing to exist. (mining would be a different issue)
How many satellites will there be? From the ad, it seems there will be 18 to 24 cubesats? Each one connected to a ground station or each other?
How many satellites depends on funding:
- 4 - a demo, with coverage gaps, high latencies
- 16 - adequate, with some periods/areas of high latency
- 24 - ideal target
- 32 - super duper

sweet ... got a view that shows southern hemisphere ground stations (e.g. australasian)?
That's all I can release for the moment. Every landmass except Antarctica should have full coverage.
With space, you get much higher latencies than on the ground.
To get full coverage over populated areas of Earth, one requires multiple orbital planes, resulting in something like this:

Is it going to be bootstrapped as high as possible before launch, or will it have to download the entire blockchain while in orbit? LOL
heh, definitely loading the chain prior to launch. That's part of the pre-flight tests in fact.Of course! Right?
I mean, the day before launch, copy over all the blocks*.dat and other files needed. Then turn it on while it's still here, keeping it running as long as possible until right before launching to sync up the last possible minute.
Then when it's in space, uh, ... well, I don't know how it works, but I guess it's already turned on while it's flying there.

I made this picture in Paint.
Let me know if I understand this or not. The lines are supposed to be, well, line of sight communication between ground stations and each other.
Could someone post info about the required equipment to recieve the BitSat broadcast in a average laptop?
If possible post links to amazon for the equipment.

Particularly, whether the BitSat would carry the full blockchain or hashed UTXO with a confirmed depth only?
As revealed at June's Bitcoin Beltway conference, the BitSat satellites will carry the full blockchain, and fully validate every block sent to it.
This is in contrast with other systems that simply broadcast a datastream without validation, and therefore require much higher levels of trust than with BitSat.

Also some of these ideas are worth discussing as they have implications for significantly changing the computational resources required for a fully-validating bitcoin node ... and thus h/ware requirements for the BitSat cubes most likely.

In case the goverment goes nuts about Bitcoin and decides to shut down the entire internet, satilletes launched by fat Bitcoin whales could be what saves the day.
lets first settle bitcoin on earth...
Kryptoradio are broadcasting blockchain data in a 7.5kbps channel on the UHF band using the DVB-T1(or possibly)T2 codec in Finland. Using the Digital Radio Mondiale codec you could broadcast =>7.1kbps over a 5kHz channel on SW/MW/LW. Although renting SW transmitter broadcast time costs around $25k per month for 24/7/365 broadcasts. 5kHZ though is about a quarter of the bandwidth that current AM radio broadcast stations use on MW or LW.
Another idea to look at terrestrial broadcasts although this time with full duplex is UHF IEEE 802.11ah meshnetworks. With a good external antenna you could get very good local range at 900Mhz so it could really work well for mesh-networking. The first IEEE 802.11ah chips are supposed to come out next year while the protocol should be finalised by 2016. Plus it's an unlicensed band so no one would need a ham license to set up a low power node.

What kind of data rates are you hoping to achieve with your cubesat? I think small satellites definitely have their place, but we are currently running a broadcast data service over all of North America, Europe, and MENA and have a minimum continuously bitrate of 56 kbps. We'll soon have access to a 50 Mbps channel and will be fully global. It's tough to get those kinds of numbers with small satellites, mostly due to power and heat issues.
Of course, we need a lot more bandwidth because we are a general platform for broadcast data; bitcoin blockchain broadcasting will only be a small slice of the overall data carousel.

Currently stuck in ITAR queue, waiting for US State Dept. to clear things which non-US people already known about and have access to...
