Date posted: 27/02/2010 Satellite navigation is having an enormous impact on our daily lives. In practical terms it means the only place left to get lost is indoors, where satnav signals fail to reach. But one ESA project is changing that. With initial results presented at last week's Techno/Innovation Days, the DINGPOS (Demonstrator for Indoor GNSS Positioning) project combines a highly-sensitive receiver capable of picking up GPS and Galileo signals indoors with additional positioning methods. These include accelerometer and gyroscope sensors, local WiFi-based positioning and ?map-matching? - associating available location data of its user in terms of a computer model of the building concerned, like a character moving through a video game. ?Global Navigation Satellite System (GNSS) signals are intended for outdoor use of course,? said David Jimenez-Ba?os, overseeing one of two DINGPOS contracts for ESA. ?They can pass through windows and walls however - depending on the material used - though the signals are hugely attenuated. Our receiver is 10 decibels more sensitive than the best commercially available equipment, meaning it can detect GNSS signals that are 10 times weaker.?
