ADVANCED FUNCTIONS
5.1
MAGNETIC COMPASS (HEADING)
Magnetic compass (HEADING) shows directions related to the magnetic north.
It is made with solid state sensors along the 3 axes, ensuring correct functionality even if not fully leveled.
5.2
G-METER
The G-meter is made of solid state G-sensors along the 3 axes; its value (G-METER) shows the number of “G” at
which we are subjected (1G = an acceleration of 9.8m/s
2
or 32.174ft/s
2
).
5.3
INERTIAL PLATFORM (AHRS)
The inertial platform (AHRS) produces data
regarding space location: pitch, roll and yaw.
Made by a data acquisition system with a complex
processing algorithm and 9 solid state sensors: 3
accelerometer sensors, 3 magnetometers and 3
gyroscope sensors.
Note : Keep in mind that the position in which you
are holding your instrument as you turn it on, will
self calibrate the inertial platform.
5.3.1
PITCH
Points out the angle of rotation compared to the lateral axis.
5.3.2
ROLL
Points out the angle of rotation compared to the longitudinal axis.
5.3.3
YAW
Points out the angle of rotation compared to the perpendicular axis.
Note: All three values (pitch, roll and yaw) can be found on the "STANDARD”
layout of PAGE 11.
