5 Hardware

5.1 MVN Link

The standard MVN System consists of a combination of hardware and software. The previous section

described how to install the software. The following will provide an overview of the hardware, which

includes the MTx’s, Body Pack, Sync Station and Access Point; and how to assemble the devices into

the mounting system (Lycra suit or MVN Mounting straps).

5.2 Motion Trackers (MTx)

The MTx is a complete miniature inertial measurement unit with integrated 3D rate gyroscopes

measuring angular velocities 3D linear accelerometers measuring accelerations including gravitational

acceleration, 3D magnetometers measuring the (earth) magnetic field, and a barometer to enable

measurement of atmospheric pressure.

Two types of motion trackers are integrated in the suit, the MTx, and MTx-STR. These are identical on

the inside but have different connectors, as can be seen in Figure 2 and Figure 3.

The back of the MTx displays various regulatory notices and 2D

barcodes used by Xsens for quality control and tracking, as well

as the MTx product code (MTx2-4A7G6) and serial number

(SN).

A Velcro strip is attached to the back of the MTx tracker around

the sticker in order to allow for easy mounting of trackers onto

the suit.
