Mobile Personal Emergency Response (mPERS) requires a number of providers and complex technologies to work as well and as simply as we all expect. Here is a quick summary of what happens when an mPERS emergency locator is activated (i.e., SOS button is pushed).
- First, the emergency locator initiates a connection to the GPS network to determine its current location. This connection is complete rapidly because a local database is maintained on the device that identifies the address of each satellite in the constellation. This enables a very quick “fix” and also enables what is called a 3D fix where up to 4 satellites work together to triangulate the device and provide a very precise location. A basic rule of statistics, the larger the sample size, the more precise result.
- Second, while the location is identified, the proprietary SecuraTrac platform called ReliaTrac, uses a number of algorithms to rationalize the data being returned from the GPS module. This enables our platform to smooth-out or improve the results returned from GPS.
- Third, at the same time the location is being calculated, a call is being made to the target programmed into the device. This can be a 24 x 7 professional emergency response center in the United States, Australia, Canada or any of the 120 countries we serve. Or, this can be a friend or family member. In the case of a family-monitored solution, SecuraTrac devices can call up to 4 numbers in succession such that if the first number is not answered, the second will be called and so forth.
- Fourth, once a call is answered the location of the caller is sent and seen on a map so that the emergency responder can see where the caller is located and can talk to them to get them the help that they need.
