The default local reference coordinate system is East-North-Up (ENU). In addition, the MTi 1-s
module has predefined output options for North-East-Down (NED) and North-West-Up (NWU).
Orientation resets have an effect on all outputs that are by default output with an ENU reference
coordinate system.
For the MTi-7/8, the Local Tangent Plane (LTP) is a local linearization of the Ellipsoidal
Coordinates (Latitude, Longitude, Altitude) in the WGS-84 Ellipsoid. Velocity data calculated by
the sensor fusion algorithm is provided in the same coordinate system as the orientation data,
and thus adopts orientation resets as well. For the MTi-3, the Latitude, Longitude and Altitude
can be stored in the non-volatile memory of the MTi. Refer to the
MT Low-level Communication
Protocol Document for more information. The default location stored in memory is that of the
calibration setup in Enschede, the Netherlands.
Triggering and Synchronization
The MTi 1-series supports a limited set of synchronization options. Please refer to BASE for
