Japanese telco NTT DOCOMO has selected Finland-based Nokia Solutions and Networks’ (NSN’s) advanced location system, which supports Assisted Global Navigation Satellite System (A-GLONASS) positioning technology, in order to improve its location-based services, such as navigation, local information services and concierge services. According to a press release, in urban areas with high-rise buildings it is challenging to acquire enough visible GPS satellites needed for positioning; by adopting A-GLONASS technology, the number of visible GPS satellites can be supplemented with GLONASS satellites, thus improving the positioning success rate. Hiroshi Nakamura, managing director of NTT DOCOMO’s core network development department, said: ‘Location-based services are clearly important to customers… In future, our customers will be able to enjoy location-based services even in places where buildings are packed closely together.’
