Liquor experts are working hard to raise awareness of the potential interference with GPS devices in order to prepare for the inevitable users. When users know they are facing traffic jams, they can take steps to reduce the impact.
"GPS interference depends largely on the line of sight," Buensel explained. "Knowing that there is GPS jammer nearby is useful, so you can move the antenna." He said that other solutions might include a holding system like an oscillator or a supplementary system like Loran.
Military system designers can often use techniques such as beam steering or antenna nulling to prevent GPS signal blocking. "There is a solution, depending on what you want to do and what the precise positioning is to you," Buensel said.
