Google Inc. (Nasdaq: GOOG) is acquiring satellite company Skybox Imaging Inc. for $500 million as it works to bolster its mapping services and improve Internet access.

The all-cash deal is subject to adjustments, the Mountain View, California-based company said on its website today. Skybox has designed satellites to capture images and deliver them to customers with details down to less than a meter.

“Skybox’s satellites will help keep Google Maps accurate with up-to-date imagery,” Google said on its website. “Over time, we also hope that Skybox’s team and technology will be able to help improve Internet access and disaster relief -- areas Google has long been interested in.”

Google is scouring the technology universe for deals that push into new markets and bolster its traditional services, including mapping and search. The company is also looking for new ways to offer online services to users through Project Loon, which it unveiled last year to help connect people in rural or remote areas to the Web using balloons and other machinery. In April, Google said it bought Titan Aerospace, a maker of high- altitude, solar-powered satellites that provides access to data services around the world.
