Giving the victims of oppression, aggression, and brutality a video camera with a satellite uplink changes the adage that history is written by the victors, and therefore ultimately may change the world towards peace.
I imagine maybe thousands of such cameras being air dropped to a place like Congo. Perhaps there is genocide going on there. Instead of sending in troops to stop the genocide, we send cameras to document what is going on, changing the incentives and rewards of the genociders even if they succeed.
There are some difficult technical problems that must be solved. How low-power can one make such a camcorder? The live satellite uplink may consume a lot of power, too, though that may be compensated for by a larger antenna on the satellites and error-correcting codes. Yes, satellites plural because probably a constellation in low earth orbit will be needed because of the low power requirement of the transmitting cameras.
The cameras must transmit over an open protocol so that no one entity that controls a constellation may censor the broadcast. There may be several constellations controlled by different, perhaps competing entities. Spread spectrum must also be employed so that the enemy cannot jam the transmission. These two requirements may contradict each other.
In certain hot zones balloons or mesh networks may be effective for broadcasting and receiving the transmissions.
Cameras should have GPS in order to location stamp and time stamp the transmissions, but must have the ability to turn the GPS off. GPS also consumes a lot of power.
Upon receipt of the broadcast the video must be immediately pushed into a censorship resistant medium like Freenet.
The storage requirements of all these videos is staggering.
