... General The Fastrax UC530 is an OEM GPS Antenna Module with the Mediatek MT3339 receiver. The module has ultra small form factor 9.6x14 mm, height is 1.95 mm nominal (2.25 mm max) and can be assembled with SMT reflow soldering. The Fastrax UC530 receiver provides extremely low power and very fast TTFF together with weak signal acquisition and tracking capability to meet even the most stringent performance expectations ...

... The UC530 module supports embedded logger function called LOCUS and when enabled it can log position information to internal flash memory; default log interval is 15 seconds that provides typically > log capacity. The LOCUS can be enabled by NMEA command $PMTK185,0*22. Contact Fastrax support for details on Locus usage. ...

... Power supply The Fastrax UC530 module requires two separate power supplies: VDD_B for non-volatile back up block (RTC/Backup RAM) and the VDD for digital parts and I/O. VDD can be switched off when navigation is not needed but if possible keep the backup supply VDD_B active all the time in order to keep the non-volatile RTC & RAM active for fastest possible TTFF ...
