GPS base class

The GPS class is a base class for nonvisual objects that can read and process global positioning system information. The SerialGPS object implements all the methods and properties of this base class.

Properties

GPS property	Datatype	Description
ClassDefinition	PowerObject	An object of type PowerObject containing information about the class definition of the object or control.
ConfigParams	String	Customization property that is currently undefined.
DeviceHandle	UnsignedLong	Read-only value containing a device-specific handle.
RawData	String	Read-only, raw, NMEA-formatted data without any parsing for validity.
Vendor	String	Customization property that is currently undefined.

Events

GPS event	Occurs
Constructor	When the object is created
Destructor	When the object is destroyed

Functions

GPS function	Datatype returned	Description
Close	Integer	Closes a GPS communications channel if one is open and deactivates the data handlers.
GetFix	GPSFix	Populates the GPSFix structure with values from the current fix.
GetHeading	GPSHeading	Populates the GPSHeading structure with values from the current heading.
GetSatellitesInView	GPSSatellitesInView	Populates the GPSSatellitePosition and GPSSatellitesInView structures with position information from the current satellites in view.
Open	Integer	Initializes GPS data handlers and opens a communications channel. You can use an optional string argument to force-feed a single set of GPS data without opening a communications channel. If this argument is used, the data acquisition behavior of derived classes (SerialGPS) remains undefined.
