Abstract:
A digital data acquisition system was developed to obtain data from a Sperry laser gyroscope strapdown inertial measurement unit for error model verification. The system consisted of a laboratory test set-up with the inertial measurement unit IMU on the Genisco rate table and inputoutput interfaces such that meaningful IMU sensor data was recorded on magnetic tape with absence of a microprocessor. The recorded data was processed on the CDC 6600 digital computer by a specially developed program which formats the data in accordance to desired specifications. The calibration sequence for error model verification was a 6-position dynamic test for the laser gyros and a 6-position static test for the accelerometers. The result is a reliable and flexible system that can obtain data from the IMU in the laboratory for analysis. Author
