Why we are using old fashioned radio transmitters versus G.P.S (global positioning systems)?
We have been asked several times the question of why we are using old fashioned radio transmitters versus G.P.S (global positioning systems), the short answer is this. Global Positioning System (GPS) equipment in a emergency search situation is less durable, the battery has to be changed too frequently, it is bulky to be worn, can fail in bad weather, and it’s signal is often unde-tected indoors, under trees, and in any area that blocks sunlight. Another major reliability factor is the power source(s). GPS detection and notification systems for the wandering individual rely on AC power while their personal GPS equipment relies on batteries that last hours or 1-2 days. The Project Lifesaver battery pro-vides a continuous signal for 30-45 days.
