Shielding

Shielding the RF circuitry generally is ineffective because the interference is received by

the GNSS antenna itself, the most sensitive portion of the RF path. The antenna cannot

be shielded because then it could not receive the GNSS signals.

There are two solutions, one is to move the antenna away from the source of interference,

and the other is to shield the digital interference source to prevent it from getting to the

antenna.
