That's binary for the ASCII "SOS" which means Save Our Ship, it's the universal distress code.
It would take you 24 days to send that message. On day one, your first bit is a 0, so you use a black tile. On day two, the second bit is a 1, so you use a white tile.
The satellite imaging system photographs your house and sees alternating tile colors on different days. You try to find the signal of these tiles among the noise of everything else changing in the satellite photo.
It's a completely impractical way to send messages. :(
