content: Subseries 5 consists of technical notes, design notes, memoranda, drawings, and blueprints documenting the development of the first generation (primarily the NAV 1000/NAV 1200), handheld GPS unit produced by Magellan. The first generation of GPS were single channel receivers and were quite simple. The NAV 1000 was 8.75" x 3.5" x 2.25" and weighed only 1.5 pounds. The NAV 1000 converted GPS satellite information into a satellite/navigation (sat/nav) positioning.  It used Gallium arsenide (GaAs) a compound of the elements gallium and arsenic, and monolithic microwave integrated circuit (MMIC) technology to reduce its size and power consumption. GaAs is a semiconductor used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows. The device sold for approximately $3,000 dollars.
