Trident missiles (a type of ICBM currently being carried aboard US submarines) do just that.

Once launched a Trident, using a camera, gets a fix on a single specific star. It then uses the data on that star's position to correct for any errors in its internal guidance system.

There are also star trackers in use by spacecrafts.
