The former had an improved guidance subsystem that directed the missile more accurately towards the calculated intercept point, rather than using the "typical" proportional navigation method.
In [10], a bias proportional navigation guidance (BPNG) law was developed, in which the desired impact time and angle were achieved simultaneously.
