Everything You Need to Know About GPS Medical Alert Systems
GPS medical alert systems are widely available in the 21st century. GPS (Global Positioning System) is a satellite-based location identification technology commonly found in electronic products. Car navigation systems and driving apps for smartphones all use GPS to help you reach your destination. Now, GPS technology is used in medical alert systems to create more efficient devices.
Alert1 offers two mobile GPS medical alert systems: Kelsi Pro mobile medical alert and PAX Plus mobile + home fall mobile medical alert. Thanks to these two alarm systems, our members are protected anywhere they go.
The History of GPS Technology
Like Cheetos or deli meats, GPS technology was funded by U.S. Department of Defense. The original purpose was to accurately coordinate and target locations for military purposes. During the Reagan administration, the government opened up the technology for broader public use. By the Clinton administration, civilian use far outpaced military use. Today GPS technology powers much of what we do, including the PAX Plus and Kelsi Pro mobile medical alert systems.
How GPS Medical Alert Systems Work
GPS is a constellation system of 29 earth-orbiting satellites. It takes 24 satellites to provide coverage around the world. The other five satellites serve as backups. The satellite flight paths are arranged so that at any time anywhere on earth, there are always four satellites visible.
The GPS chip in your PAX Plus or Kelsi Pro medical alert receives radio signals from the four visible satellites. The chip then determines your location in a process called trilateration. Kelsi Pro and PAX Plus use the signals from at least three of those satellites to determine your precise location. Alert1 then knows where to send you the help you need, fast.
While our GPS medical alert systems may sound complicated, you won’t have to do anything special to send us your location. Just press the button when you need help, and we’ll send emergency services your way.
Mobile Technology as Backup
PAX Plus and Kelsi Pro also use U-TDOA (Uplink Time Difference of Arrival) location technology. U-TDOA is a position-location technology used by mobile phone networks.
The Kelsi mobile medical alarm system also uses U-TDOA. Kelsi is our classic mobile medical alert help system. If you're looking for a mobile system that travels with you without fall detection, Kelsi is the way to go.
Kelsi, Kelsi Pro, and PAX Plus all use U-TDOA to help keep you safe. But what exactly is U-TDOA?
U-TDOA works through microprocessors in our mobile alerts that connect with receivers in cellular towers. They pick up the signal from GPS medical alert systems and determine your location. Our mobile alarm help buttons calculate the time it takes a signal to travel from your device to the Location Measurement Units (LMUs) on the tower. By using the timing information from multiple LMUs, we can know your precise location.
