GPS ToolKit Pro is an ActiveX object that makes it easy to add GPS support to any Visual Basic, Visual C++, Delphi, Excel, or scripting project that supports ActiveX controls. GPS data (including lat/lon, speed, course, altitude, and dozens of other datasets) can be accessed through GPS ToolKit's properties, and GPS ToolKit's multithreaded event-based architecture notifies your application when data has been updated, saving you from having to write messy polling routines.

GPS ToolKit Pro:

Works with all GPS units that support NMEA 0183 output (that's just about all of them!)
Provides an intuitive interface that makes GPS data availible through straightforward properties.
Can playback NMEA 0183 input files in various speeds, including real-time playback.
Notifies your application when fix, naviagation, or status has been updated.
Reports position, altitude, speed, and distance in a number of formats and units.
Requires only one file to be distributed along with your application.
Works with development environments such as Visual C++, Visual Basic, and Delphi, as well as scripting environments like Microsoft Word and Excel.
Can be redistributed royalty-free (as part of your application).
Does not require knowledge of COM or ATL to use.
Supports Windows NT 4.0, Windows 98, Windows ME, Windows 2000, and Windows XP.
Is written in Visual C++ 6.0 using ATL 3.0 so that it is small and fast.
