A craft (e.g., an aircraft, a spacecraft, a watercraft, a vehicle such as an automotive vehicle or a rail vehicle, or any suitable mobile platform) may incorporate a first inertial measurement unit. A calibration unit incorporating a second inertial measurement unit may be mounted to the craft with a mount point. One or more first inertial measurements may be received from the first inertial measurement unit and the second inertial measurement unit. One or more antenna pointing controller calibration parameters may be determined based at least in part on the first inertial measurement(s) and the second inertial measurement(s). An antenna pointing controller may be configured with the determined calibration parameters and may control a steerable antenna subsystem mounted with the mount point utilizing the determined calibration parameters. The mount point may be keyed such that inertial measurements with the mounted calibration unit are applicable to the mounted steerable antenna subsystem.
