Researchers from Sandia National Laboratories and Ohio State University are taking experimental navigation technology to the skies.

They are pioneering a backup system to keep an airplane on course when it cannot rely on global positioning system satellites.

The idea is to use these alternative signals to calculate a vehicle's position and velocity.

The research is supported by Sandia's Laboratory Directed Research and Development program.

Satellite signals are expected to be strong, but there may be dead zones due to the cone-shaped transmission pattern that narrows closer to the source.

Satellite coverage over rural areas, like much of New Mexico , may be too sporadic to be useful.

Eventually, a functional navigation system will need to match signals to their transmitters in real-time.
