Three Russian satellites have failed to enter orbit after they were launched on a rocket from the Baikonur cosmodrome in Kazakhstan.

Russian aerospace experts said the Glonass spacecraft and the upper-stage booster carrying them probably fell into the Pacific Ocean near Hawaii.

The satellites were to be part of a navigation system meant to rival GPS.

Russia has already successfully launched a number of the Glonass satellites this year.
