![]() But JPL senior research technologist Darmindra Arumugam helped work out a mathematical and technological framework to enable their practical application by using lower frequencies to extend the range of this technology while ensuring highly accurate location data. A type of electromagnetic field, MQS fields have been largely overlooked by researchers as a viable positioning tool because of rapid drop-off as a function of distance. POINTER removes that unpredictability by harnessing magnetoquasistatic (MQS) fields. This may be a minor annoyance when trying to find the location of an appointment, but it could be a life-or-death situation when trying to locate firefighters in a burning building. Though radio waves offer a reliable means to determine your location in a relatively open space, they can become unpredictable if you go indoors or find yourself surrounded by high buildings. Unlike positioning technologies such as GPS or radio-frequency identification, POINTER doesn’t use radio waves. POINTER is one of those life-saving solutions.” “We want them to know that we have their backs, that we are working to give them the tools they need to ensure their own safety. “Even with all of the advances made in firefighting technology, we still lose far too many firefighters each year,” said Greg Price, who leads S&T’s first responder research-and-development programs.
