	This function is used with two purposes: 1 -> To set the gnss_synchro 2 -> A set_gnss_synchro command with a valid PRN is received when the system is going to run acquisition with that PRN. We can use this command to pre-initialize tracking parameters and variables before the actual acquisition process takes place. In this way we minimize the latency between acquisition and tracking once the acquisition has been made.

	This function starts the tracking process.

	This function sets a flag that makes general_work to stop in order to finish the tracking process.

	This function disables the HW multicorrelator in the FPGA in order to stop the tracking process.

general_work()

		gr_vector_int &	ninput_items,
		gr_vector_const_void_star &	input_items,
		gr_vector_void_star &	output_items )

General Work.

reset()

void dll_pll_veml_tracking_fpga::reset

(

)

This function disables the HW multicorrelator in the FPGA in order to stop the tracking process.

set_channel()

void dll_pll_veml_tracking_fpga::set_channel	(	uint32_t	channel,
		const std::string &	device_io_name )

Set the channel number and configure some multicorrelator parameters.

set_gnss_synchro()

void dll_pll_veml_tracking_fpga::set_gnss_synchro

(

Gnss_Synchro *

p_gnss_synchro

)

This function is used with two purposes: 1 -> To set the gnss_synchro 2 -> A set_gnss_synchro command with a valid PRN is received when the system is going to run acquisition with that PRN. We can use this command to pre-initialize tracking parameters and variables before the actual acquisition process takes place.

start_tracking()

void dll_pll_veml_tracking_fpga::start_tracking

(

)

This function starts the tracking process.

stop_tracking()

void dll_pll_veml_tracking_fpga::stop_tracking

(

)

This function sets a flag that makes general_work to stop in order to finish the tracking process.
