Citat:
The SiRFprima consists of an ARM11 processing unit, a high-performance location engine that supports both GPS and Galileo satellite systems and an on-chip DSP. This new chipset can do positioning via both the GPS and upcoming Galileo system with great accuracy. The new European Galileo grid should be operational by 2013.
Citat:
The SiRFprima promises to get a satellite fix even faster than its predecessor could, now needing less than five seconds on average. While the SiRF Star III only had 20 channels, the SiRFprima has 64 to work with. SiRF also enhanced the sensitivity of the receiver from -159dBm to -161dBm.

Predvidoma v drugi polovici 2008
Žal o zmanjšani porabi nič ne piše

Verjetno jih rabi več, da lahko sprejema signale iz GPS in Galileo satelitov hkrati, drugače res nima smisla.
