The Iowa State Patrol has bought a GPS system that lets a trooper track a suspect vehicle instead of giving dangerous chase. Currently only one State Patrol car is equipped with the StarChase system but more could be coming. Sgt. Scott Bright says the system is a new technology that will protect alot of people. The trooper pushes a button to launch a GPS tracking projectile from the patrol vehicle's grille. The projectile sticks to the fleeing vehicle, allowing the trooper to back off. When the fleeing vehicle slows or stops, troopers can close in and make an arrest.
