GPS 3.3.8

  by Chip Orange This app has not been rated. XML Feed for GPS 3.3.8

a shared object library which is an interface to GPS receivers which use (or simulate) a standard COM port, for app developers. It also provides the same positional information via the Windows 7/8 Location Sensor API if a GPS receiver isn't available.It allows development of apps which have location-based capabilities, without having to understand the difficulties of interfacing with a GPS receiver (similar in concept to the Windows 7 location-sensor, however it works with all versions of Windows). it allows you to determine your current position, heading and speed from a GPS receiver linked to your pc. It also optionally plays various sound files for events such as aquisition of signal, obtaining a fix, losing a fix, loss of signal, changing quality of fix, etc. More than one app can interface with the GPS concurrently.Includes a sample app which inserts your current latitude/longitude into your active window when you press a hotkey.It also includes several lat/lon related classes and routines; useful even when no GPS receiver is connected. These provide the distance between two points, the bearing from one point to a second, or the relative bearing from a current heading to a specified point.
