• On slow moving vehicles, where a lack of speed means errors in the GPS
velocity are relatively large in proportion to the vehicle speed.
• On heavy vehicles like trains and plant equipment that can’t accelerate quickly
enough (while above the initialisation threshold) to trigger dynamic
initialisation.
• Where it is difficult to ensure the vehicle travels in straight line during dynamic
initialisation—airborne and waterborne applications.
Real-time output during initialisation
During the initialisation process the INS does not output measurements in real-time. Instead,
the system runs one second behind, allowing GNSS information to be compared to
information from the inertial sensors. However, once initialisation occurs, the system reduces
this lag to zero. It does this in a linear way over a period of 10 seconds after initialisation. The
Status LED indicates whether the system is outputting in real-time or not.
