According to O2, operators and manufacturers remain uncertain over the deployment schedule for Galileo and the likely quality of its signal.
Although the mobile industry wants to put some form of global navigation satellite system (GNSS) functionality into phones, some companies within it are hesitant about which system to use.
The only GNSS currently in action is GPS, the American system designed and run by the US military. Already familiar to many people as the technology behind vehicle satellite navigation and fleet tracking, a server-assisted version called assisted GPS or A-GPS — which promises quicker location-finding — is set to be used in handsets around the world.
However, Galileo — which should be fully operational by the end of 2008 — will supposedly provide greater accuracy, leaving some in the industry wondering whether they should invest in compatibility with GPS, Galileo or both (a path that appears to have been taken by the UK-based chipset manufacturer CSR). This indecision, said O2, is slowing things down.
