Sometimes we forget exactly what Sirius satellite entails but the most recent story to come from the corporation brings the nature of their business back to the forefront.

Sirius XM Radio is planning the launch of another satellite, the Sirius FM-5 satellite, to accompany the three existing satellites currently providing radio signals to subscribers.

The new geostationary satellite will improve reception after it reaches its fixed position in orbit above North America, remaining in one place while the other units stay in constant motion over the continent.

The Sirius FM-5 satellite is planned for launch on June 29th, 2009. Stay tuned for more news as we get closer to the date.
