Acceleration Errors in Astro-navigation

Published online by Cambridge University Press:  18 January 2010

Extract

Squadron Leader Bower gives some data regarding the accuracy of astronomical navigation in high-speed aircraft. No attempt was made to assess the absolute accuracy of astro-navigation, but the distance, when plotted on the chart, between pairs of sights taken on the same star was measured, with the following results.

The average spread between beam shots is consistently greater than that between fore and aft shots, and it is possible that acceleration errors, which can be sizable for high-speed aircraft, are responsible for this.

Errors Due To Aircraft Accelerations. Errors due to the combined effect of the aircraft's movement and the Earth's rotation give rise to errors in the position line.
