Q1. The vertical reference unit of a three-axis data generator is equipped with a gyro with :
2 degrees of freedom and vertical spin axis
Q2. While inertial platform system is operating on board an aircraft, it is necessary to use a device with the following characteristics, in order to keep the vertical line with a pendulous system:
with damping and a period of about 84 minutes.
Q3. In an Inertial Navigation System (INS), the main causes of Cumulative Distance errors are:
wander in the levelling gyros and integrator errors in the second stage of integration.
Q4. What is known as the “Schuler Period” has a length of:
84.4 minutes
Q5. In an Inertial Navigation System (INS), the main causes of Cumulative Track errors are:
initial azimuth misalignment of the platform and wander of the azimuth gyro.
