A cyclone monitoring project has used these techniques to disseminate warnings and positional data to a wide array of users.

Much work on reliable fusion of positional data from multiple sensors remains to be done.

There are two basic entities that need to be taught (or programmed): positional data and procedure.

A communication network or satellite network is then used to transfer this positional data to a centralised collection point.

But the positional data had come with an admonition to strict secrecy-and nothing else.

Used to report the basic positional data of a track.

The implications of the positional data hit the officers with full impact.

This is due to physical properties within the system, be it mechanical or laser guided, that corrupt positional data.

These systems can use a tilt, pressure or other sensor carried by the probe to collect positional data.

Fast neutrons can also be made into a beam to provide accurate positional data.
