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.
