The GPS receiver measures how long it takes a certain   radio signal to travel from the GPS satellite(s) to itself, and from   that, the receiver calcu â¦ lates the distance.

For other uses, see Popcorn (disambiguation). Popcorn is a type of corn that expands from the kernel and puffs up when heated. Popcorn is able to pop like amaranth grain, sorghum, quinoa, and millet. When heated, pressure builds within the kernel, and a small explosion (or pop) is the end result. Some strains of corn are now cultivated specifically as popping corns.
