5.2

GNSS Antenna Interface

In addition to the RF antenna interface PVS8 also has a GNSS antenna interface. The GNSS 
antenna installation and connector are the same as for the RF antenna interface (see 

Section 

5.1.1

). For use with GPS and GLONASS it is recommended to use a GPS and GLONASS ca-

pable antenna.

It is possible to connect active or passive GNSS antennas. In either case they must have 50 
Ohm impedance. The simultaneous operation of CDMA and GNSS has been implemented. 

PVS8 provides the supply voltage VGNSS for the GNSS active antenna (3.05V). It has to be 
enabled by software when the GNSS receiver shall becomes active, otherwise VGNSS should 
be off (power saving). VGNSS is not short circuit protected. This will have to be provided for by 
an external application. The DC voltage should be fed back via ANT_GNSS_DC for coupling 
into the GNSS antenna path. 

Figure 5

 shows the flexibility in realizing the power supply for an 

active GNSS antenna by giving two sample circuits realizing the supply voltage for an active 
GNSS antenna - one with short circuit protection and one with an external LDO employed.
