1 Second Fix With New GPS Ublox-5 Chip
By D Dunbar in GPS. February 3, 2007
u-blox have announced a new GPS chip, called u-blox 5, which will be launched at the 3GSM later this month. This new chip boasts an amazing 1 second TTFF (Time to first fix), high sensitivity at -160 dBm and very low power consumption at under 50mW.
The 1 second TTFF is of particular interest as it is much quicker than the current fastest, the SiRf Star III at around 30 seconds.
Possibly even more exciting than the speedy TTFF is that the u-blox will be Galileo compatible from day one.
"As soon as Galileo signals become available, our receivers will be able to simultaneously receive and track these signals too, via a simple software upgrade."
The benefits that Galileo signals will bring are as follows:
* Better coverage from more satellites
* Higher positioning accuracy
* Better multipath mitigation
* Higher overall reliability and availability
* Software upgrade upon deployment of Galileo system by the EU
Galileo is the EU and the European Space Agency's alternative to the US run GPS and promises to provide a higher precision to all users than is currently available.
