How to Remove a Heading Error From Gyroscope
- 1). Dock the vessel. Tie the vessel to the pier.
- 2). Instruct the vessel's engineer to open the breakers for the inertial guidance system. Disconnect the system's battery backup.
- 3). Read the vessel's location from a global positioning system (GPS). The GPS system uses an artificial constellation of satellites to establish the latitude, longitude and elevation of the GPS receiver.
- 4). Reboot the inertial guidance system. Enter the GPS coordinates in the system's computer terminal.
