antenna input of the module) should not exceed 30 dB. The noise figure should be ≤
1.5dB.
3.3 Serial Port Settings
In UART operation (defined by the external pull-up resistor as outlined in Minimum
Configuration) the default settings are:
 NMEA, 4800 baud, 8 data bits, no parity, 1 stop bit, no flow control
3.4 Improved TTFF
In order to improve the TTFF (Time To First Fix), it is recommended to keep Vcc
supplied at all times. This will allow taking advantage of sophisticated low power
mode features of the SiRFstarIV ROM chip set.
