Abstract:
In this research the problem is the development and simulation of Transfer Alignment algorithm for an aerial launch space launch vehicle. In the references there is no complete study on development of this algorithm for the case space launch vehicle. In order to develop the algorithm, the carrying airplane and the space launch navigation systems are considered as the Master INS and Slave INS respectively. First a 6DOF simulation of the airplane is presented. Then the desired inputs for simulation of Master and Slave INS are generated. Also the differences of the inputs of Slave INS caused by the distance between the Master and Slave INS is considered. Master INS performs as an ideal INS and the error parameters of IMUs is added to Slave INS inputs. Next inorder to calibrate the Slave INS outputs before the launch, the Transfer Alignment algorithm is developed. The effect of the airplane maneuver on the convergence rate of the algorithm during the calibration process is presented too. Finally the simulation of space launch vehicle flight to target orbit checks the quality and accuracy of the algorithm
