Detailed Description

Extended position fix information.

This class provides position and navigation data that may come from various sources:

GNSS receiver (primary source)
Last known position (when GNSS signal is lost)
User-defined position (when manually moved on map)
Dead reckoning (calculated from last known position and movement)

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Member Data Documentation

◆ Cog

double PlugIn_Position_Fix_Ex::Cog

Course over ground in degrees.

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 261 of file ocpn_plugin.h.

◆ FixTime

time_t PlugIn_Position_Fix_Ex::FixTime

UTC time of fix.

If GNSS available: Time from most recent GNSS message
If GNSS watchdog expired: Current system time

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 290 of file ocpn_plugin.h.

◆ Hdm

double PlugIn_Position_Fix_Ex::Hdm

Heading magnetic in degrees.

May be NaN if heading sensor data is not available.

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 276 of file ocpn_plugin.h.

◆ Hdt

double PlugIn_Position_Fix_Ex::Hdt

Heading true in degrees.

May be NaN if true heading cannot be calculated (requires both magnetic heading and variation).

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 283 of file ocpn_plugin.h.

◆ Lat

double PlugIn_Position_Fix_Ex::Lat

Latitude in decimal degrees.

May represent last known position rather than current true position if:

GNSS signal is lost
Position has been manually set by user on map

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 250 of file ocpn_plugin.h.

◆ Lon

double PlugIn_Position_Fix_Ex::Lon

Longitude in decimal degrees.

May represent last known position rather than current true position if:

GNSS signal is lost
Position has been manually set by user on map

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 258 of file ocpn_plugin.h.

◆ nSats

int PlugIn_Position_Fix_Ex::nSats

Number of satellites used in the fix.

Will be 0 if:

GNSS watchdog has expired
Position is not from GNSS

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 298 of file ocpn_plugin.h.

◆ Sog

double PlugIn_Position_Fix_Ex::Sog

Speed over ground in knots.

May be NaN if speed cannot be determined.

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 267 of file ocpn_plugin.h.

◆ Var

double PlugIn_Position_Fix_Ex::Var

Magnetic variation in degrees, typically from RMC message.

Examples: /home/runner/work/main/main/opencpn/include/ocpn_plugin.h.

Definition at line 270 of file ocpn_plugin.h.
