acquire!(
    acq_plan,
    signal,
    prns;
    interm_freq,
    doppler_offset,
    noise_power
)

This acquisition function uses a predefined acquisition plan to accelerate the computing time. This will be useful, if you have to calculate the acquisition multiple time in a row.

acquire(
    system,
    signal,
    sampling_freq,
    prns;
    interm_freq,
    max_doppler,
    dopplers
)

Perform the aquisition of multiple satellites with prns in system system with signal signal sampled at rate sampling_freq. Optional arguments are the intermediate frequency interm_freq (default 0Hz), the maximum expected Doppler max_doppler (default 7000Hz). If the maximum Doppler is too unspecific you can instead pass a Doppler range with with your individual step size using the argument dopplers.

    system,
    signal,
    sampling_freq,
    prn;
    interm_freq,
    max_doppler,
    dopplers
)

Perform the aquisition of a single satellite prn in system system with signal signal sampled at rate sampling_freq. Optional arguments are the intermediate frequency interm_freq (default 0Hz), the maximum expected Doppler max_doppler (default 7000Hz). If the maximum Doppler is too unspecific you can instead pass a Doppler range with with your individual step size using the argument dopplers.

    signal,
    sampling_freq,
    prns;
    interm_freq,
    max_doppler,
    coarse_step,
    fine_step
)

Performs a coarse aquisition and fine acquisition of multiple satellites prns in system system with signal signal sampled at rate sampling_freq. The aquisition is performed as parallel code phase search using the Doppler frequencies with coarse step size coarse_step and fine step size fine_step.

)

Performs a coarse aquisition and fine acquisition of a single satellite with PRN prn in system system with signal signal sampled at rate sampling_freq. The aquisition is performed as parallel code phase search using the Doppler frequencies with coarse step size coarse_step and fine step size fine_step.
