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.
Subseries 6, Second Generation, 1988-1996, consists of technical notes, design notes, memorandums, drawings, and blueprints documenting the development of the second generation (primarily the NAV 5000) handheld GPS unit produced by Magellan. The NAV 5000 used five channels working simultaneously to locate and collect data from GPS satellites. The units GaAs circuitry rapidly processed the data received from the satellites to compute current location, altitude, velocity and navigation in under one minute. The NAV 5000 was designed primarily for marine use. Other second generation products included: OEM Brain, OEM 1/2 Brain, Nav 500 Pro, NAV 100M5, Skaynav, Fieldpro, NAV 5200 PM, NAV 5000A, NAV 5000D, DX, DLX, Pro mark V, and the Map 7000.
Subseries 7, Third Generation, 1986-1994, consists of technical notes for the development of the third generation (primarily Meridian and Trailblazer models) of Magellan GPS devices. Third generation models were intended for the lower end of the GPS market and were compact hand-held (size, weight, battery life) and a retail price that was reasonable. Other third generation devices included: the meridian, Trailblazer, AIV10 OEM, Skatblazer, NAV 6500 PM, Meridian/TB/SB XL, NAV 1200 Pm, NAV 1200 XL PM, NAV DLX 10, Promark X, and the Pro Mark X-CM.
Subseries 8, Swiss Army Chip (SAC) Development, 1987-1995, consists of technical notes, diagrams and drawings, and specifications for the development of a digital chip used in Magellan GPS products. Don Rea and Norm Hunt of Magellan are credited with naming the chip. The chip combined several elements--GPS DPS channels, correalators, real time clock, alarm timer, interval timer, keyboard interface, display interface, precise timing, power sequencing, memory decoding, code generators, and beeper driver, to name a few--which allowed the development team reduce the overall power, size, and cost of the chip. Magellan outsourced the manufacture of the SAC.
Subseries 9, Technical Products Development Seminars, 1997-1998, consists of documentation for nine seminars in a series of technology seminars initiated by the product develpment group at Magellan. The seminars were created to keep all staff up to date on past, present, and future technology developments at Magellan. The nine seminars cover the history of Magellan GPS technology and address specific areas of development such as antennas, circuits, signal processing, software, navigation needs, and radio frequency. Other information includes tables providing comparisons for the first, second, and third generations, timelines, SAC chip characteristics, and product shipping dates. The seminars provide a good foundation for understanding what the product development staff accomplished. Researchers should consult Series 8 which documents some of the technical seminars.
Subseries 10, Specifications, 1992-1994, consists of preliminary, functional, and system requirements describing technical characteristics for several Magellan products.
Subseries 11, TriQuint Semiconductor Materials, 1986-1992, consists of materials documenting TriQuint Semiconductor, Inc.'s work. TriQuint was a division of Tektroninix, Inc., a manufacturer of analog and mixed signal gallium arsenide (GaAs) integrated circuit products. TriQuint supplied custom radio frequency (RF) and Gallium arsenide (GaAs) chips for Magellan's hand-held GPS systems and tested its chips. Documentation includes trip summaries and observations to TriQuint by Don Rea, a Magellan engineer as well as technical drawings, memorandums, development schedules, invoices, purchase orders, and tests results, production quantity and costs, and specifications. In 1986, Don Rea met Gary Barta, then principal engineer at TriQuint through his frequent visits to the company. Barta led the engineeering development of the an integrated circuit which combined the GPS L-band low-noise pre-amplifier, UHF local oscillator, down converter and high speed digital divisers on a single gallium-arsenide chip. Nothing like this had been done before for a cost senstive commerical application. Barta later joined Magellan in November 1988 as Vice President of Engineering and made the chip he had designed actually work in the environment of a hand-held product.
Series 4, Marketing and Promotional Materials, 1985-1997, is divided into six subseries: Subseries 1, Market Research, 1985-1993 and undated; Subseries 2, Product Literature, circa 1990s; Subseries 3, Advertisements, 1988-1995 and undated; Subseries 4, Press Releases, 1988-1996; Subseries 5, Presentation Materials, 1990-[1997?] and undated; and Subseries 6, Newspaper and Magazine Clippings, 1988-1996 and undated.

Biographical / Historical:
Ed Tuck of the Boundary Fund, a venture capital firm specializing in technologies founded the Magellan Systems Corporation in 1986 and served as its director from 1986 to 1993. Tuck assembled the initial team of Norm Hunt, Larry Weill, Val Wong, and Sab Ifune to conduct a feasibility study in early 1986 to pursue commercial markets for products based on global positioning system (GPS) technology. Magellan introduced the first handheld commercial GPS receiver in 1989 and was the first company to make GPS devices affordable to consumers. Magellan introduced the first handheld commercial GPS receiver in 1989 and was the first company to make GPS devices affordable to consumers. The company successfully introduced GPS products into the marine, professional, military and automotive and general aviation markets.
The Global Positioning System (GPS) began as a United States Department of Defense Program in the 1960s with a navy system known as Transit (first satellite navigation system). Two other projects soon followed, Timation (satellite to broadcast accurate time reference) and Air Force Project 612B, which began in the 1970s. In 1973, the development of the Navigation Signal Timing and Ranging Global Positioning System (NAVSTAR) began under the management of the Air Force. Designed by the military, the system provided twenty-four positioning satellites under all- weather conditions using passive (non-transmitting) receivers. This kept a user's presence from being detected as a result of the receiver. Although primarily for military use, the system also offered a less-precise coded signal for civilian use.
GPS uses a group of twenty-four earth-orbiting satellites which broadcast continuously. The data being broadcast can be processed by a portable receiver to determine a user's position, velocity and time. GPS has three parts: 1) space part with twenty-four satellites; 2) ground part with monitor and 3) user part with receivers that process the signals and calculate position.
In the spring of 1986, the Magellan team published a specification for a custom mixed signal RF (radio frequency) integrated circuit and by fall 1986, had a breadboard (used in prototyping of electronics) and began software development and testing. Magellan focused its research, product engineering, and design activities on the development of GPS receivers that were application-specific, software-intensive, reliable, lower power, easy to use, and affordable.
From 1986 to 1988, the Boundary Fund provided the venture capital for feasibility studies and the initital product design. By 1988, the company occupied its first stand-alone facility in Monrovia, California with thirty-five employees. In May 1989, the company's first product, the NAV 1000, shipped, and in that same year, the company entered the military market with the NAV 1000M. The company entered the professional market in January 1990 with the NAV 1000 PRO, the world's first hand-held GPS product. By 1991, Magellan moved to a new facility in Dimas, California and introduced advanced five-channel technology. It also incorporated in the United Kingdom (UK) as Magellan Systems to handle product distribution in the rest of the UK and Europe.
The SkyNAV 5000 was introduced in 1992 for the general aviation market, and in the same year, hand-held differential GPS technology for the marine market appeared. Magellan was purchased by Orbital Sciences Corporation in 1994. In 2001, Thales Group purchased the Magellan division of Orbital Sciences, and the company became known as Thales Navigation. In 2006, a private equity firm, Shah Capital Partners, and other investors purchased Thales Navigation, and the company was officially renamed Magellan Navigation. Magellan (also known as MiTAC Digital Corporation) is a wholly-owned subsidiary of MiTAC International Corporation and promotes and sells products and services under the Magellan brand name. Magellan is headquartered in Santa Clara, California.
The Division of Work and Industry holds related artifacts (GPS receivers, computer electronics boards, computer chips, antennas, packaging, components, circuit boards, keyboards, a Swiss Army Chip (SAC), and receiver brackets).
