In Database Setup the Time Synchronization system can be defined in a wizard with two pages: the first page will set up what type of time tag is used (e.g. because all timing critical sensor data is already UTC time tagged in the system itself or when no multibeam sounders are used. Surveying without the Time Synchronization Adapter should only be done when the timing requirements are not so strict, e.g. If this is not used, an averaging of incoming time tags is used this will be less accurate but stable. Time synchronization can be very accurate (better than 0.5 milliseconds) when using a Qinsy Time Synchronization Adapter which interfaces a TTL 1 pulse per second (Time Synchronization) signal from a GPS receiver into the computer. Only a single Time Synchronization system is allowed per template. Naming background: PPS is a slightly old fashioned name there are many more possible ways to synchronize the Qinsy clock, e.g. In Qinsy the name PPS (Pulse Per Second) was commonly used to refer to time synchronization of the internal Qinsy clock to UTC.Īll the incoming data that does not have its own UTC timetag is timestamped in the driver, based on this internal Qinsy clock.

GeneralĪ Time Synchronization System is used to synchronize the internal Qinsy clock and the Microsoft Windows system clock to UTC time. This How-to describes the Time Synchronization functionality.
