GPS reception and satellite navigation equipment
Install the transmitting part in a flat, dry area, separate from the electronic components of the vehicle, away from humidity and
vibrations. If the transmission is impulsive it must be at a distance of at least one meter away from other devices.
The GPS antenna must be installed so as to have the maximum visibility possible of the sky.
In fact, as the signals received from the satellite are at very low power (approximately 136 dBm), almost any obstacle can influence
the quality and performance of the receiver.
The following should therefore be guaranteed:
● an absolute minimum angle of vision of the sky of 90°
● a distance no less than 30 cm from any other antenna
● a horizontal position and never underneath any metal which makes up part of the cab structure.
Moreover:
● the ROS value (Stationary Wave Ratio) must be as close as possible to the unit (the recommended value is 1.5), while the
maximum must never be greater than 2 in the GPS frequency range (1575.42 ± 1.023 MHz).
● the ANTENNA GAIN values must be as high as possible and guarantee a sufficient level of spatial uniformity, characterised by
deviations in relation to the average value to the order of 1.5 dB in the 1575.42 ± 1.023 MHz band.
Radio installation
Refer to the information contained in the Use and Maintenance Manual
Additional equipment
Power for the equipment, when the voltage required is different to that for the system, must be obtained using a suitable DC/DC
12-24V converter if not already provided. The power cables must be as short as possible, avoiding any twists (coils) and maintaining
the minimum distance from the reference plane.
Note
If devices are fitted which could interact with the electronic systems already present (retarders, additional heaters, power take-offs,
air conditioners, automatic gearboxes, telematics and speed limiters) please contact IVECO in order to establish the compatibility
checks.
▶ The use of non approved transmitters or supplementary amplifiers could seriously impede the
correct functioning of the electrical/electronic devices normally supplied, with negative effects
for the safety of the vehicle and/or the driver.
▶ Any damage caused by the use of non-certified transceivers or by the application of additional
amplifiers is not covered by the warranty.
The vehicle system is set up to supply the necessary power to the equipment provided, for each of which, as part of their function,
the specific protection is assured as well as the correct sizing of cables.
The installation of additional equipment must include suitable protections and should not overload the vehicle system.
The connection of the added users to ground must be made with an adequately sectioned cable, as short as possible and made to
allow for any movements of the added equipment with respect to the chassis of the vehicle.
Having the need for higher capacity batteries, due to added loads, it is appropriate to request the optional with increased batteries
and alternators.
