A method and apparatus are provided to control artificial lighting using accurate geographical location, date and time, in order to activate such electrical activity only during needed periods of actual terrestrial darkness related to sun elevation. Accurate, real-time calculation of sun elevation relative to geographical location and date/time allow natural lighting characteristics such as natural light spectrum and intensity to be matched to artificial lighting, in order to provide a smooth transition in ambient lighting and to save energy. An apparatus according to the invention comprises a global positioning system (GPS) element for determining latitude, longitude, altitude, date and time and a calculation element for determining sun elevation angle accurately. A specific embodiment requires only desired sun elevation angle inputs from the user for controlling electrical switches in a control system.

In a GPS-equipped device such as a smart phone or a tablet computer with a compatible operating system, a useful dynamic display of directional and timing information is provided based on GPS data obtained through conventional means processed according to computational modules or applications stored on the device. These displays include a solar timer, a compass dial and other date, time and location-based information. Underlying the displayable information is a database of information that is processed with input from an accurate compass employing a calculated reference line based on two time-separated GPS readings and a direction parameter.

A method uses a smart phone having SMS text and location (GPS) capability for automatically generating messages and contacting emergency services through SMS messaging capability rather a verbal communication along with the vital information related to the caller in an emergency situation. The emergency response center uses the information to parse standardized emergency SMS messages to quickly yield critical information related to the number, priority and the geographical distribution of the emergency cases for planning of the most efficient response with available resources. The data and prioritizing may take into account time of day or night by position of the sun and moon relative to current location of the smart phone.
