INFO:

We have evaluated about dozen of different GPS receivers before selectiong this one and we found this to be the most sensitive and with the least power consumption of all devices we tested (Mstar, Skytraq etc), we found that SIRF STAR III chipset allow satelite tracking even withing buildings and with the only 38mA power consumption this device beats all other we have tested.
