Reduced Order Strapdown Terrestrial INS Algorithm


Aِِbstract:Strapdown system algorithms are the mathematical definition of processes whichconvert the measured outputs of Inertial Navigation System (INS) sensors that are fixed toa vehicle body axis into quantities which can be used to control the vehicle.In this work, a reduced and fast terrestrial strapdown INS algorithm was developedand implemented for three-degree of freedom (3DOF). The evaluation of the algorithm isbased on the accuracy of the proposed algorithm with real data.
