The Gundam Sadalsuud is the second of the four 2nd generation Gundams, all based on the GN-000 0 Gundam, to be developed by Celestial Being engineers at Krung Thep. In battle, firepower alone is not sufficient to guarantee victory, gathering intelligence is equally important. For this reason, Sadalsuud’s design focused on sensing functions, as they are the means to gather intelligence. It has a variety of sensors (e.g. E-sensors) mounted all over its body, with the most prominent ones being the round, green sensors mounted on the suit’s knees, left chest, forehead and on the pair of shoulder-mounted Sensor Shields.

Taking into account the mobility of a humanoid machine, most of Sadalsuud’s sensors are on the front, with only two rear sensors located on the pair of rear waist thruster units. The low amount of rear sensors is because it is difficult to find locations unaffected by the GN Particles released from the torso-mounted GN Drive, which is used for propelling the suit. The rear waist thruster units have diverting fins to prevent their own exhaust GN Particles from affecting the sensors.
