Macros

#define NRF_MODEM_GNSS_TIMING_SOURCE_RTC   0
 Real time clock (RTC).
 
#define NRF_MODEM_GNSS_TIMING_SOURCE_TCXO   1
 Temperature compensated crystal oscillator (TCXO).
 

Detailed Description

Used to select which sleep timing source GNSS uses.

Using TCXO instead of RTC during GNSS sleep periods might be beneficial when used with 1PPS. When GNSS is not running all the time (periodic navigation or duty-cycling is used), 1PPS accuracy can be improved by using TCXO. It may also improve sensitivity for periodic navigation when the fix interval is short.

Note
Use of TCXO significantly raises the idle current consumption.
