The study describes a mathematical error model of a platformless inertial navigation system and focuses on using Allan variance as a method for estimating such instrumental errors of sensors, such as zero signal bias instability, angle random walk and rate random walk. The paper shows the results of the work of the mathematical error model, the model being constructed using the estimated instrumental errors of a sample of sensor assembly which consists of three ring laser gyroscopes and a three-axis accelerometer unit.
