GPS.NET and GIS.NET are built upon a common assembly known as the "GeoFramework Core" which contains several common objects such as Position, Distance, Angle, Speed and so on. The objects contain methods you can use to calculate distance and bearing. You can also calculate the minimum travel time to a destination, total length of a route, and several other calculations. With GPS.NET, you will not need to write code for trigonemtric functions because they are already built-in for you.

The Compass control is a user control which can help you navigate to any destination. You can rotate the entire control for "track-up" navigation, and turn the needle to either the current real-time bearing, or the bearing to the next destination. The Compass can automatically utilize real-time GPS data or display a custom value that you set manually. The Compass uses the same multithreaded, double-buffered rendering technology as GIS.NET to deliver liquid-smooth animation effects. The GPS Control Toolbox is sold separately from GPS.NET.

The Speedometer control is a user control which can help you display the current speed. You can set the control to any maximum speed and change the units to any Metric or Imperial unit type. You can also instruct the control to automatically display real-time speed from a GPS device, or set the control to a manual value. The Speedometer uses the same multithreaded, double-buffered rendering technology as GIS.NET to deliver liquid-smooth animation effects. The GPS Control Toolbox is sold separately from GPS.NET.

The Altimeter control is a user control which can help you display either the current altitude above sea level, or depth underwater. You can set the control to any value and change the units to any Metric or Imperial unit type. The Altimeter can be set to automatically display the real-time GPS altitude, or you can set the control to a manual value. The Altimeter uses the same multithreaded, double-buffered rendering technology as GIS.NET to deliver liquid-smooth animation effects. The GPS Control Toolbox is sold separately from GPS.NET.

The SatelliteViewer and SatelliteSignalBar controls are the most popular controls in the GPS Control Toolbox. These controls can help you quickly determine where GPS satellites can be found relative to your current location. You can also easily determine whether radio signals are being received strongly enough to calculate your location. These controls can be customized to use any color or pattern, and can also pick up special WAAS, EGNOS and MSAS corrective satellites. These controls use the same multithreaded, double-buffered rendering technology as GIS.NET to deliver liquid-smooth animation effects. The GPS Control Toolbox is sold separately from GPS.NET.

The GPS Control Toolbox can be customized to blend with any user interface. You can change the outline color, fill color, texture, or background of any part of any control. You can resize the controls to any shape, and have controls partially overlap one another. You can enable or disable the special Vista-like smoked glass effect for super-smooth animation. You can also control whether rendering for controls takes place on a separate thread to maximize performance of your user interfaces.
