Description of the Sensors
This chapter describes the characteristics of the sensors that are
used in the PCAN-GPS in short form and gives instructions for use.
For additional information about the sensors, see the technical
specifications (on page 27) and the data sheets of the respective
manufacturers (Appendix D on page 38).
2.1
Receiver for Navigation Satellites
(GNSS)
The u-blox MAX-7W receiver is designed for the following global
navigation satellite systems (GNSS):
GPS (USA)
GLONASS (Russia)
Galileo (Europe)
QZSS (Japan)
SBAS (supplementary)
To receive a satellite signal, an external antenna must be connected
to the SMA socket . Both passive and active antennas are suitable.
An active antenna is included.
The use of GPS and GLONASS cannot happen simultaneously. On
the one hand, the external antenna must match the respective
system (the supplied one can receive both), on the other hand, the
GNSS receiver must be switched.
For a faster position fix after turning on the PCAN-GPS, the internal
RTC and the internal backup RAM can be supplied by the button
