NEWARK, N.J. — A New Jersey man faces tens of thousands of dollars in fines after regulators say he interfered with a satellite system at one of the nation's busiest airports while masking his whereabouts from his employer.

The Federal Communications Commission says Gary Bojczak admitted he installed a jamming device in his company-owned pickup to thwart his employer's GPS.

The FCC says the jamming device interfered with a satellite system that enhanced navigation signals that used GPS data to aid aircraft approaching, departing and on the ground at Newark Liberty International Airport.

Officials say Bojczak surrendered the jamming device after his vehicle was stopped at the airport in 2012.

His faces nearly $32,000 in fines after the FCC found he unlawfully operated an illegal GPS jammer and interfered with authorized communications.
