A New Technique Makes GPS Accurate to an Inch

GPS is an utterly permeative and wonderful technology , but it ’s increasingly not accurate enough for innovative demands . Now a team of researchers can make it accurate right down to an column inch .

Regular GPS registers your location and velocity by measuring the sentence it takes to receive signal from four or more satellites , that were send into quad by the military . Alone , it can assure you where you are to within 30 feet . More of late a technique called Differential GPS ( DGPS ) improved on that resolution by adding primer coat - found reference station — increase accuracy to within 3 metrical unit .

Now , a squad from the University of California , Riverside , has developed a technique that augments the even GPS data point with on - board inertial mensuration from a sensor . in reality , that ’s been tried before , but in the past it ’s want large computers to immix the two data point stream , rendering it ineffective for utilization in cars or mobile devices . Instead what the University of California team has done is create a set of new algorithms which , it lay claim , slenderize the complexity of the calculation by several order of magnitude .

In turn , that let GPS organisation in a mobile gadget to calculate position with an truth of just an column inch . The research ispublished inIEEE Transactions on Control Systems Technology .

The squad hopes that the fresh GPS building block could be used where truth is far more important that it was in the past . Autonomous vehicles is an obvious software , where knowing exactly where the fomite is on the route is absolutely crucial — but it could be include in your phone , too .
