ZylGPSReceiver 3.89
Delphi &
C++Builder Component
ZylGPSReceiver
is a Delphi & C++Builder component collection that communicates
with a GPS receiver (Global Positioning System).
It returns latitude, longitude, altitude, speed, course, heading
and many other useful parameters of the current position and the
parameters of the satellites in view. The component is extended
to calculate distances and make conversions between different measurement
units.
This component works with any NMEA 0183 compilant GPS receiver connected
to one of the serial ports. NMEA 0183 (or NMEA for short) is a combined
electrical and data specification for communication between marine
electronic devices such as echo sounder, sonars, Anemometer (winds
speed and direction), gyrocompass, autopilot, GPS receivers and
many other types of instruments. It has been defined by, and is
controlled by, the US-based National Marine Electronics Association.
The component supports GPS (USA), GLONASS (Russia), BeiDou (China),
Quasi-Zenith (Japan) and Galileo (EU) satellites, but theoretically
you can use for any other satellite as well.
You can use it also with USB, IrDA and Bluetooth devices, because
these devices have a driver that redirects the input from the USB,
IrDA or Bluetooth port to a virtual serial port (you can check it
in System/Device Manager/Ports). If your USB device is not provided
with such a driver, then use a USB controller whose vendor provides
a virtual serial port driver, such as FTDI
or use a USB/RS-232 adapter. For Garmin receivers you have to install
Spanner
software.
To connect to
an Android smartphone's GPS, you can download GPS2Bluetooth application
from playstore and connect your phone to your PC through bluetooth
(GPS2BT service).
The component
collection contains more components. The following image displays
the object model:
ZylCustomGPSReceiver
is a custom Delphi & C++Builder component, which is designed
to be the base class of any kind of GPS receivers. This component
contains an NMEA decoder engine and it works with any NMEA compatible
GPS receiver.
You can extend this class easily to process NMEA data from any kind
of sources as files, sockets, web services and so on.
Supported NMEA sentences: GPGLL, GPGGA, GPGNS,
GPVTG, GPRMC, GPGSA, GPGSV, GPZDA, GPMSS, GPAAM,
GPRMB, GPBWC, GPWPL, GPRTE, GPXTE, GPHDG, GPHDT, GPHDM, GPGST
ZylGPSReceiver
(ZylSerialGPSReceiver) is
an extension of ZylCustomGPSReceiver,
which processes NMEA data from serial, USB or Bluetooth ports. It's
thread based, which means that the reading process is handled by
a different thread.
ZylUdpGPSReceiver
is an extension of ZylCustomGPSReceiver,
which processes NMEA data from an UDP socket. It uses Indy 9 socket
components (http://www.indyproject.org),
which is preinstalled in Delphi 6 and later. You can find the full
source code of this component in the download package.
Indy
9 is usually used with Delphi 4, Delphi 5, Delphi 6, Delphi
7, C++ Builder 4, C++ Builder 5, C++ Builder 6, later versions using
Indy 10.
ZylUdp10GPSReceiver
is an extension of ZylCustomGPSReceiver,
which processes NMEA data from an UDP socket. It uses Indy
10 socket components (http://www.indyproject.org),
which is preinstalled in Delphi 2005 and later. You can find the
full source code of this component in the download package.
ZylFileGPSReceiver
is an extension of ZylCustomGPSReceiver,
which processes NMEA data from a text file.
ZylGpxGPSReceiver
is an extension of ZylCustomGPSReceiver, which processes data from
GPX files.
ZylNMEADecoder
is an extension of ZylCustomGPSReceiver,
which decodes NMEA data from any source, but you have to feed it
with NMEA sentences programatically from the Decode method.
ZylNMEAEncoder
is a class to encodes position data to NMEA format.
With
this components you will be able to develop robust GPS Delphi or
C++Builder applications. Possible applications can be:
*
Vehicle Navigation
* Marine Navigation
* Fleet Management
* Emergency Locator
* Geographic Surveying
* AVL and Locating-Based Services
* Personal Navigation or touring devices
* Tracking devices
* Sporting and Recreation
* Farming
* Time synchronization
With ZylGPSReceiver
you can also create web distributed applications.
The main idea behind is very simple:
*
Create a desktop application or a Windows service that will run
locally on the server, collecting gps-data from the receiver and
saving them in the database.
*Create
a web service that will provide the requested gps-data from the
database to the webpages.
The Global Positioning
System (GPS) is a worldwide radio-navigation system formed from
a constellation of 24 satellites and their ground stations.
GPS uses these satellites as reference points to calculate positions
accurate to a matter of meters. In fact, with advanced forms of
GPS you can make measurements to better than a centimeter!
In a sense it's like giving every square meter on the planet a unique
address.
GPS receivers have been miniaturized to just a few integrated circuits
and so are becoming very economical. And that makes the technology
accessible to virtually everyone.
These days GPS is finding its way into cars, boats, planes, construction
equipment, movie making gear, farm machinery, even laptop computers,
tablets, mobile phones or smart watches.
GPS technology has matured into a resource that goes far beyond
its original design goals. These days scientists, sportsmen, farmers,
soldiers, pilots, surveyors, hikers, delivery drivers, sailors,
dispatchers, lumberjacks, fire-fighters, and people from many other
walks of life are using GPS in ways that make their work more productive,
safer, and sometimes even easier.
The
demo version is fully functional in Delphi and C++Builder IDE, but
it displays a nag dialog (the licensed version will, of course,
not have a nag dialog and will not be limited to the IDE). The package
includes demo programs for Delphi and C++Builder and a help file
with the description of the component.
