Analytic models of computational errors (truncation, word length, integration scheme, integration interval, and sensor output resolution) presented were developed through digital simulation of navigation sensors and different data processing schemes; error models demonstrate techniques by which computational processes can be properly designed for different applications and magnitude of computational errors controlled; test data obtained during centrifuge testing of strapdown system are presented showing good agreement with attitude computational error models.
