Abstract:
1. A platform attitude adjustment augmentation apparatus for increasing platform attitude adjustment range for a platform supported on and raised relative to ground by jacks of given stroke lengths, the apparatus comprising: jacks configured to support a platform at spaced-apart locations on the ground by extending to contact the ground and to raise the platform relative to the ground; jack drive mechanisms drivingly connected to the respective jacks; a dual axis tilt sensor carried by the platform and configured to detect a platform attitude relative to Earth gravity and to transmit corresponding signals representing the platform attitude; and a controller connected to each of the jacks through their respective jack drive mechanisms, configured to receive the signals from the tilt sensor, and programmed to adjust the platform attitude to a desired platform attitude relative to Earth gravity in response to the signals received from the tilt sensor, by controlling the operation of the jacks and coordinating jack movement as the jacks are adjusting platform attitude, the controller being further programmed to:
