The Wall Street Journal reports that Google intends to launch a fleet of 180 satellites. The sources for this report were people.

That’s right: people.

Apparently the paper’s reporters have yet to master the skill of picking up useful tips from dogs or migratory birds.

My hunch is that the sources here work for Google — but that’s just a hunch.

Google plans to spend more than $1 billion on a fleet of satellites to extend Internet access to unwired regions of the globe, people familiar with the project said, hoping to overcome financial and technical problems that thwarted previous efforts.

Details remain in flux, the people said, but the project will start with 180 small, high-capacity satellites orbiting the earth at lower altitudes than traditional satellites, and then could expand.

Google’s satellite venture is led by Greg Wyler, founder of satellite-communications startup O3b Networks Ltd., who recently joined Google with O3b’s former chief technology officer, the people said. Google has also been hiring engineers from satellite company Space Systems/Loral LLC to work on the project, according to another person familiar with the hiring initiative.

Mr. Wyler has between 10 and 20 people working for him at Google and reports to Craig Barratt, who reports to Chief Executive Larry Page, one of the people said. Mr. Wyler couldn’t be reached.
