There may now be a way for your business to build tightly-coupled GPS/INS systems. It used to be that only large
aerospace companies had that capability. A new approach makes the systems vastly easier to design, assemble,
test and modify. The approach has been worked through, published, proved in field trials, and made available in the
form of a software package called GINI. Small and medium-sized businesses are successfully using the package.

Welcome to Knight Systems, a leader in the creation of navigation software and navigation systems concepts.
Please have a look around the web site.
Company Mission
The vision of Knight Systems is to bring tightly-coupled GPS/INS within reach of small enterprises serving niche
markets, by making it possible for the enterprises to build their own tightly-coupled systems.
Company Profile
Established in 1991, Knight Systems is a small, entrepreneurial business owned and operated by Donald T. Knight.
Knight Systems is in business to transform navigation systems from hope to reality, by providing conceptual
innovation, analysis, simulation, R&D support, and software. Knight Systems serves a variety of companies ranging
from large civilian and defense contractors to small startup companies, as well as government and university labs.
Mr. Knight brings in-depth GPS, INS, and Kalman filtering expertise, having worked on GPS for 35 years, having
participated in several GPS/INS projects, and having successfully implemented and field tested tightly-coupled
GPS/INS systems of his own design. He helped design the first GPS navigation system and first tightly-coupled
GPS/INS ever built, the Magnavox X-Set. Most recently, he developed GINI®, a concept that vastly simplifies and
speeds the development of tightly-coupled GPS/INS systems.
Mr. Knight has been consulting for the last 24 years to Stanford Telecom, Trimble, Allen Osborne Associates, the
U.S. Navy, and others. For 12 years prior to that, he was a Senior Staff Engineer/Scientist at Magnavox Research
Laboratory, the original prime contractor for GPS user equipment .
At Jet Propulsion Laboratory, he wrote the Functional Requirements Document for the Voyager Spacecraft Radio, the
one that flew to Neptune. He also wrote computer simulations of radio nonlinear effects that predicted lab
measurements accurate to 0.1 dB.
His solution for GPS carrier ambiguity resolution is known in the industry as the "Knight Method."
Member of IEEE and ION.
He holds a B.S. with High Honors and with Distinction in Physics from San Diego State University and an M.S. in
Engineering from UCLA.
