Function nrfxlib_sys::nrf_modem_gnss_timing_source_set

pub unsafe extern "C" fn nrf_modem_gnss_timing_source_set(
    timing_source: u8
) -> i32

Sets the used timing source during GNSS sleep.

@details 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.

Default value: #NRF_MODEM_GNSS_TIMING_SOURCE_RTC

@note Use of TCXO significantly raises the idle current consumption.

@note This feature is only supported by modem firmware v1.3.0 or later.
