Welcome to the VisualGPSXP multipurpose GPS utility. Please note that VisualGPSXP uses specific NMEA sentences to display data graphically.

VisualGPSXP is a general purpose utility for monitoring the output of a GPS receiver. Using the NMEA data from the GPS receiver, VisualGPSXP will display various statuses graphically. Tools such as a survey utility average the position and shows accuracy of the GPS receiver in a static application. Other features such as analog gauges show altitude, speed, vertical speed and direction. One additional feature is the capability to connect and share a GPS receivers data over the Internet.
