Abstract:	IT IS EVIDENT that the volume of polar and tram-polar air traffic will increase. The northern polar region must already be recognized as an important military operations area. It could also become very important from a commercial standpoint. In the south polar region further exploration is still to be done; much of this work will be accomplished through aerial surveys. For whatever reason, navigation remains a problem of particular import in polar flying. It may be that radio aids will eventually provide sufficient coverage to serve as the primary navigation facility. In any case, a requirement will continue to exist for a selfcontained secondary capability. This secondary system should probably be at least semi-automatic in view of present aircraft speeds. A Doppler unit combined with a dead-reckoning computer of the analog type would fulfill such a requirement by providing a position computing function. It is with these thoughts in mind that the following material is presented.
