The ASM-135A ASAT is a historic air-launched anti-satellite missile, designed in the early 1980s.
The firing procedure is subject to development. Known so far is: You need to fly inside the ground track of the target, against its direction of travel. At the right lead angle between target and you, pull up and release ASAT at about 65°. Don't drop your nose to soon, for preventing collision with the ASAT. It as a small delay between drop and ignition of the first stage, and accelerates initially at rather modest 5g.
The ASM-135A uses the Black Dart standard for its attachment orientation: Direction has to point outside the pylon (typically -Y), rotation points forward (+Z). If attached and released, the ASM-135A automatically switches to automatic sequence.
