GPS Improved Accuracy
Research conducted by Universidad Carlos III de Madrid (also known as UC3M) have found they can boost conventional standard GPS devices by a magnitude of 90% and significantly decrease the margin of error to improve positioning and location. UC3M see an objective to integrate their system into smartphones. This could assist the emergency services to improve pinpointing in emergency cases, in addition to added capability where handsets have modules included using existing conventional GPS capability.
