LEA-5T GPS IC资料
u-blox 5 GPS and GALILEO Receiver Module with Precision TIming
The LEA-5T supports precision GPS TIming for demanding
posiTIoning applicaTIons such as Femto cells and WiMAX basestations.
It features a Time Mode function whereby the GPS
receiver assumes a stationary 3D position, whether programmed
manually or determined by an initial self-survey. Stationary
operation enables GPS timing with only one visible satellite and
eliminates timing errors which otherwise result in positioning
errors. An accuracy of up to 15 ns is achievable by using the
quantization error information to compensate the granularity of
the time pulse. A built-in time mark and counter unit provide
precise time measurement of external event inputs.
