1. A mobile surveillance system (MSS), the MSS comprising:
an extendable mast configured to be secured to a mobile terrestrial platform and provide an elevated modular sensor mount;
a motor configured to control movement of the extendable mast between a stowed position and a deployed position; and
a logic device configured to communicate with the extendable mast and the motor, wherein the logic device is configured to:
adjust a speed setting of the motor based on a position of the extendable mast between the stowed position and the deployed position and based on a direction of movement of the extendable mast towards the stowed position or the deployed position; and
adjust a torque of the motor based on the position of the extendable mast and based on the direction of movement of the extendable mast;
wherein:
during a deployment of the extendable mast, the speed setting and torque of the motor are adjusted based on the position of the extendable mast in at least a first zone, a second zone, a third zone, or a fourth zone between the stowed position and the deployed position;
the first zone is an unstow operation zone, with the speed setting of the motor adjusted to a first speed setting and the torque of the motor adjusted to a first torque;
the second zone is a main operation zone, with the speed setting of the motor adjusted to a second speed setting and the torque of the motor adjusted to a second torque;
the third zone is a pre-park operation zone, with the speed setting of the motor adjusted to a third speed setting and the torque of the motor remaining at the second torque;
the fourth zone is a park operation zone, with the speed setting of the motor remaining at the third speed setting and the torque of the motor adjusted to a third torque; and
the third speed setting is less than the second speed setting.
