3. Read the following text: Navy’s omega Navigation System

Four stations for the Navy-developed navigation system have been approved for operational use to facilitate operational evaluation.

The OMEGA system consists of 8 transmitters strategically located around the world. Four of these are already in operation.

The stations located in Bratland, Norway; Port of Spain, Trinidad; Haiku, Hawaii; and Forestport, New-York, will provide navigation coverage to an area of more than one-fourth of the world.

When the world-wide network is in full operation there will be transmitters in Minnesota, Hawaii, Norway, Trinidad, Japan, either New Zealand or Australia, Chile or Argentina, and La Reunion Island off the coast of Madagascar.

OMEGA, which has been under development by the Navy for some time, is an all-weather, general purpose navigational aid. The system provides navigation for aircraft, ships and submerged submarines.

The system continuously provides a position to a navigator in any weather. The operation of the receiver is quick, simple and reliable.

The transmitting stations transmit signals on 10.2, 11.3 and 13.5 kilohertzes (kilocycles). The lowest frequency and the one most generally used in OMEGA is 10.2 kilohertz.

OMEGA has a potential of providing continuous world-wide position information, accurate to one mile during the daytime and two miles at night, and will be evaluated together with other existing navigation systems as well as those in an advanced state of development in connection with the formulation of a National Navigation Plan.

The responsibility for the development of this plan was assigned to the Department of Transportation by Vice-President at the July Meeting of the National Council for Marine Resources and Engineering Development. The Department of Defence will participate in the development of the plan.
