Born of the satellite solutions provider Globalstar Inc, the SPOT Assist roadside GPS safety network is positioned to give OnStar a run for its money.

The company says that it is the world's first satellite-based roadside GPS safety service. Unlike OnStar -- a cellular based emergency system offered electively on GM models -- the SPOT Assist relies on GPS tracking and satellite communications. Its Track Progress feature even sends and saves locations and allows emergency contacts to track progress using Google Maps.

There is only one problem: Though the scheme transcends cellular limitations, it does not seem to have been designed strictly with automobiles in mind. Using SPOT Assist means taking a bulky-looking hand-held GPS unit along for the ride. OnStar, on the other hand, is a vehicle-integrated module, located right above the driver and activated at the touch of a button.

Showcasing the service at this year's CES, Tom Colby, COO of Globalstar and President of SPOT LLC, summed it up perfectly: "Our customers have been using SPOT primarily off-road and outside of cellular range to check-in with loved ones or to get help in a real emergency resulting in increased safety and security for outdoor enthusiasts."
