![]() ![]() The clock can be especially useful to verify that ExpertGPS is receiving data from your GPS, because the seconds hand will update once a second if the GPS is connected properly, even if your GPS doesn't have a lock on enough satellites to start sending position data yet. You can toggle on or off each of the Tracking Displays (Current Position, Satellites, Clock, Course). ![]() The Enable Tracking command (on the GPS menu, under Real-Time GPS Tracking) toggles real-time tracking on and off. Consult your Garmin manual for assistance with this software. ![]() On some older USB-based Garmin GPS receivers, you'll need to install the Garmin Spanner software on your computer. Click No on the GPS, and then enable Tracking in ExpertGPS to start the flow of position, velocity, and time (PVT) data from your GPS to ExpertGPS. Your GPS will recognize the connection to the computer, and ask if you want to switch to Mass Storage Mode. Instead, you can set the Interface mode on your GPS to Garmin Spanner or Garmin PVT, and then plug your GPS into the USB cable connected to your computer. Most modern Garmin GPS receivers use a USB connection, and no longer support serial NMEA. If you have a modern Windows laptop with an integrated GPS antenna, or if you are running another GPS program which is feeding location data to the Windows Location API, you can use this tracking protocol with ExpertGPS. Older Magellan and Lowrance GPS receivers had a Simulator or In-Store Demo mode, which you can use as an input to ExpertGPS if you can't take your GPS outside to get a lock on enough satellites to use the regular NMEA - GPS Active protocol. It's important that any hardware that creates a virtual COM port be fully installed, connected, and running before you start ExpertGPS, so that the virtual COM port is detected by ExpertGPS. The Serial Port list in the Tracking dialog will show every active, working COM port on your computer, including physical RS-232 ports (rare these days), and virtual COM ports created by your USB-to-Serial adapter or Bluetooth GPS. If you have a Bluetooth GPS receiver, it will also have a driver that creates a virtual COM port for ExpertGPS to use. Select that virtual COM port as the Serial Port in ExpertGPS. This adapter will come with its own driver software which will create a virtual COM port on your computer. Very few modern computers still have serial ports, so if your GPS or marine electronics output NMEA to a serial port, you will probably need a Serial-to-USB adapter to connect to your laptop. The NMEA protocol is a serial data protocol supported by almost all marine equipment, and by almost all older GPS receivers.
