Inertial navigation has had a relatively short but intense history of development, much of it during the half‐century of the Cold War, with contributions from thousands of engineers and scientists. An outline of developments in the United States is given.
There is no single, all‐encompassing design for INS/GPS integration, because there is no standard design for an INS. There may be minor differences between generations of GPS satellites, but the differences between INS types are anything but minor. There are some broad INS design types (e.g., gimbaled vs. strapdown), but there are literally thousands of different inertial sensor designs that can be used for each INS type.
What matters most from the standpoint of GPS/INS integration are the mathematical models for the different types of error sources. We present here a variety of inertial sensor error models, which will be sufficient for many of the sensors in common use but perhaps not for every conceivable inertial sensor. For applications with sensor characteristics different from those used here, the use of these error models in GPS/INS integration will serve to illustrate the general integration methodology, so that users can apply the same methodology to GPS/INS integration with other sensor error models as well.
