When WB
I
mitigation is enabled, the e
ff
ect of the interference is dramatically reduced to the
extent that, the small signal bump at the GPS L1 central frequency of 1575 MHz is clearly
visible as Figure 7-6 shows.
I
n this particular test, the interference signal caused the receiver to fall back to the less
precise DGNSS or standalone positioning modes. With WB
I
mitigation enabled however,
the receiver was able to maintain an RTK
fi
x position throughout.

Enabling WB
I
interference mitigation greatly reduces the e
ff
ect of the
interference caused by the chirp jammer.
