u-blox 6 ROM-based GPS receiver

LEA-6T precision timing moduleThe LEA-6T supports precision GPS timing for demanding positioning applications such as 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. LEA-6T is supported by the easy-to-use EVK-6T Precision Timing Evaluation Kit.
