1. A system mounted on a movable object for controlling an indicator, comprising:
- a) a controller connected to an indicator, the controller controlling activation and deactivation of the indicator;
b) a position locator, locating position of said object with respect to planet Earth, said position locator supplying data concerning each said position, while said object is moving, to a sunrise/sunset calculator;
c) said sunrise/sunset calculator programmed with data concerning at least one daily sunrise and sunset time for every geographic location on planet Earth;
d) said sunrise/sunset calculator supplying said data concerning daily sunrise and sunset times to said controller, said data corresponding to a geographic location of an antenna of said position locator with respect to planet Earth; and
e) upon stoppage of said object, said controller activating said indicator at a first time at or spaced from a sunrise time received from said calculator for a particular location where said stoppage has occurred, on a particular day and deactivating said indicator at a second time at or spaced from a sunset time received from said calculator for said particular location and day.

Abstract
A system monitors geographical information for location of an aircraft and supplies that information to a sunrise/sunset calculator that feeds location and sunrise/sunset data to a controller. The controller controls operation of a pinger, limiting its hours of operation to save battery power and extend the time period within which the pinger is audible. The hours of operation are pre-programmed to consist of a time range from sunrise to sunset or from a time after sunrise to a time before sunset.
