SiRFstarIIe/LP still uses 1,920 corrolators and 12 channels to provide fast acquisition and re-
aquisition times, while keeping peak current to under 65 mA. TricklePower extends battery
life even further by reducing average current to under 20mA. Now superior performance
features like SingleSat, SnapLock, and FoliageLock are available using less power.
processing power and the GRF2i/LP, a lower power version of the GRF2i integrated front end.
The GSW2 software completes the package providing flexible system architechture for stand-
alone GPS based products. The SiRFstarIIe/LP also supports SiRF's high sensitivity stand
alone software, SiRFXtrac and mult-mode software,SiRFLoc. When low power, low cost, and
high performance matter SiRFstarIIe/LP is the best solution.
