The Magellan Systems Corporation produced some of the earliest handheld GPS units for civilian use. In 1986 company engineers began experimenting with electronic mockups. This is the earliest “breadboard” receiver. Together with a keyboard (2010.0154.02) and power supply (2010.0154.03), this object was used to test circuitry and components at Magellan while developing the first civilian GPS receivers.
