ZylGPSReceiverAX is an an award-winning ActiveX control that communicates with a serial GPS receiver. It returns latitude, longitude, altitude, speed, heading and many other parameters of the position. This control works with any NMEA compatible receiver connected to one of the serial ports. You can use it also with USB devices, because these devices usually have a driver that redirects the input from the USB port to a virtual serial port. If your 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. The component supports US (GPS), Russian (GLONASS) and Chinese (BEIDOU) global positioning systems and GALILEO (EU) support is coming soon. The component is extended to calculate distances and make conversions between different measurement units. With this control you will be able to develop robust GPS applications in any ActiveX supporting development environment. 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
