Position Requirement of Installing Satellite Navigation
Antenna
Two satellite navigation antennas should be installed just above the rear axle of the
vehicle as far as possible along the longitudinal direction of the vehicle, as shown in
the figure below. If this is impossible due to the geometry of the top of driving cab or
other structural constraints, the longitudinal distance from the satellite navigation
antenna to the rear axle center of the vehicle should be accurately measured during the
subsequent equipment commissioning process.
Figure 18 Electro-mechanical connection drawing of AG960 (open center system)
In the transverse direction, two satellite navigation antennas should be symmetrically
installed to the edge of the driving cab top, as shown in the figure below. It is required
that the distance between two antennas should be as large as possible, at least 1m. If
1m distance is not available at the driving cab top, antenna installation bracket should
be fabricated.
