Review of the gyroscope free strap-down inertial navigation system

摘要

With domestic and international literature on the topic viewed, the study on GFSINS is summarized in this paper. Two important aspects of GFSINS have been discussed, namely the accelerometer allocation scheme and calculation method of angular velocity, meanwhile the error and precision issues of GFSINS are also briefly analyzed. In the end, possible research topics on GFSINS are discussed for further investigation.
