GPS reception and satellite navigation equipment
The transmitter part of the equipment must be installed in a flat, dry area, separate from the vehicle’s electronic components
and away from damp and vibrations.
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 (around 136dBm), 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 that is never underneath any metal making up part of the cab structure.
Moreover:
•
the SWR ratio (Standing Wave Ratio) must be as close as possible to the unit (1.5 is recommended) while the maximum must
not 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 of the order of 1.5 dB in the 1575.42 ± 1.023 MHz band.
