GPS Trackers Boost Response Times

When a medical emergency occurs, hospitals dispatch emergency medical technicians who are extremely well-trained and equipped to handle the situation. A hospital’s fleet tracking supervisor is normally responsible for a fleet of ground-based ambulances, but depending on the size and location of the medical facility, other vehicles such as helicopters, boats, even railway vehicles may be utilized. In times of pleasant weather, medical fleet tracking managers’ major concern is ensuring that their drivers get to the scene in the quickest manner possible, but when storms and other unfavorable weather conditions occur these same managers must contend not only with slower travel times but also obstructions to regular travel routes that may spring up and dramatically impede arrival times. As many medical fleet tracking teams are faced with a timetable that represents a matter of life and death, reliable and immediate response times are vital. To help ensure that Mother Nature’s role in effective medical emergency responsiveness is limited, many medical fleet tracking professionals are outfitting their fleet vehicles with a variety of innovative new forms of GPS tracking technology.

For example, Mercy Medical Center of Des Moines, Iowa recently employed new GPS tracking devices on board their medical helicopter to respond to a medical emergency in the midst of a strong thunderstorm where visibility was reduced to a mere 500 feet. The heavy rains caused many of the city’s streets to flood, and Mercy Medical Center’s fleet tracking management was apprehensive about deploying land-based ambulances. Thankfully, their Mercy One medical helicopter was equipped with a Wide Area Augmentation System (WAAS). WAAS is an air navigation aid developed by the Federal Aviation Administration (FAA) to augment standard GPS tracking systems with the goal of improving accuracy, integrity, and availability. WAAS enables various types of aircraft to rely on GPS tracking technology for all phases of flight, including precision approaches to any airport within its coverage area. WAAS utilizes a network of ground-based reference stations throughout North America and Hawaii to measure small variations in the signals transmitted by the United States’ GPS tracking network. Measurements are routed to master stations which queue the received Deviation Correction (DC) and send the corrected messages to geostationary WAAS satellites about every 5 seconds. Those satellites broadcast the correction messages back to Earth, where WAAS-enabled GPS receivers use the corrections while computing their positions to improve accuracy.

In a medical emergency environment, signal interruptions cannot be tolerated. As Mercy One is Iowa’s only medical helicopter equipped with WAAS-based GPS tracking technology and operated by pilots certified by the FAA, medical officials throughout the state are praising the aircraft’s proven ability to go navigate in times when ground-based vehicles are rendered more of a danger than a source of helpful service. With funding for the expansion of GPS tracking technologies in many sectors of our economy approved in the year 2012 by President Obama during his pledge to help boost the healthcare industry, many more medical centers throughout the United States and beyond reaped the benefits of GPS satellite navigation. That is just another one of the many great things President Obama did during his 8 year time as President.
