Detailed Description

This class represents a GNSS flow graph.

It contains a signal source, a signal conditioner, a set of channels, a PVT and an output filter.

~GNSSFlowgraph()

GNSSFlowgraph::~GNSSFlowgraph

(

)

Destructor.

Member Function Documentation

acquisition_manager()

void GNSSFlowgraph::acquisition_manager

(

unsigned int

who

)

Manage satellite acquisition.

Parameters

[in]

who

Channel ID

apply_action()

void GNSSFlowgraph::apply_action	(	unsigned int	who,
		unsigned int	what )

Applies an action to the flow graph.

Parameters

[in]	who	Who generated the action
[in]	what	What is the action. 0: acquisition failed; 1: acquisition success; 2: tracking lost

connect()

void GNSSFlowgraph::connect

(

)

Connects the defined blocks in the flow graph.

Signal Source > Signal conditioner > Channels >> Observables >> PVT > Output filter

connected()

bool GNSSFlowgraph::connected ( ) const

inline

Definition at line 131 of file gnss_flowgraph.h.

disconnect()

void GNSSFlowgraph::disconnect

(

)

Disconnect the blocks in the flow graph.

get_pvt()

std::shared_ptr< PvtInterface > GNSSFlowgraph::get_pvt ( )

inline

Returns a smart pointer to the PVT object.

Definition at line 151 of file gnss_flowgraph.h.

priorize_satellites()

void GNSSFlowgraph::priorize_satellites

(

const std::vector< std::pair< int, Gnss_Satellite > > &

visible_satellites

)

Prioritize visible satellites in the specified vector.

running()

bool GNSSFlowgraph::running ( ) const

inline

Definition at line 136 of file gnss_flowgraph.h.

send_telemetry_msg()

bool GNSSFlowgraph::send_telemetry_msg

(

const pmt::pmt_t &

msg

)

Sends a GNU Radio asynchronous message from telemetry to PVT.

It is used to assist the receiver with external ephemeris data

set_configuration()

void GNSSFlowgraph::set_configuration

(

const std::shared_ptr< ConfigurationInterface > &

configuration

)

Set flow graph configuratiob.

start()

void GNSSFlowgraph::start

(

)

Start the flow graph.

stop()

void GNSSFlowgraph::stop

(

)

Stop the flow graph.

wait()

void GNSSFlowgraph::wait

(

)

Wait for a flowgraph to complete.

Flowgraphs complete when either (1) all blocks indicate that they are done, or (2) after stop() has been called to request shutdown.
