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.

ZylGPSReceiver is an award-winning Delphi & C++Builder component collection that communicates with a GPS receiver (Global Positioning System).
It returns latitude, longitude, altitude, speed, 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. 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.

ExpertGPS is the ultimate GPS map software for planning outdoor adventures. View GPS waypoints and tracklogs from any handheld GPS receiver over aerial photos and US topographic maps. Plan your next outdoor adventure over scanned USGS topo maps and send a route directly to your GPS receiver to guide you in the field. View your GPS tracklog over an aerial photo to see exactly where you went.

ZylGPSReceiver Mobile is an event driven Compact Framework.NET component that communicates with a GPS receiver. It is designed for mobile devices such as Pocket PCs and smart phones, which run on Windows Mobile operating systems.
It returns latitude, longitude, altitude, speed, 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 compatible receiver, integrated or connected through USB, IrDA or Bluetooth, because these devices have a driver that redirects the input from the USB, IrDA or Bluetooth port to a virtual serial port.
