The UBX-G6010-ST-TM provides precision GPS timing for demanding positioning applications such as femto cells and WiMAX basestations. This GPS chip features user configurable frequency output and timepulse. An accuracy of up to 15 ns is achievable by using the quantization error information to compensate the granularity of the time pulse. The UBX-G6010-STTM features a time mode function whereby the GPS receiver assumes a stationary 3D position, whether programmed manually or determined by an initial self-survey. During stationary operation GPS timing is possible with only one visible satellite. This means that time can be output even under adverse signal conditions or in environments with poor sky visibility. A built-in time mark and counter unit provide precise time measurement of external event inputs. T-RAIM (Timing Receiver Autonomous Integrity Monitoring) is available to detect faulty GPS measurements. Raw data is also provided. The UBX-G6010-ST-TM is the ideal GPS chip solution for high-volume timing applications.
