A mobile satellite system includes a satellite communication switching office having a satellite antenna for receiving/transmitting a satellite message via a satellite from/to a vehicle using a mobile communication system, a satellite interface system, and a fleet management system including a central controller. The mobile communication system includes a housing having a shock resistant material. The housing includes end bumpers of an elastomeric material for absorbing shock experienced by the housing. The end bumpers each include recessed handles on an upper surface of the mobile communicator system and ribbed protruded finger grips on a bottom surface of the mobile communication system. The mobile communication system also includes an input device for inputting data. The input device comprises a keyboard including a rubber/carbon membrane and mounted in the housing using a first seal to prevent fluid from entering the mobile communication system between the input device and the housing. The mobile communication system also includes a central processing unit disposed in the housing that receives either data from the input device or sensor data received from the mobile sensing station. The central processing unit also outputs satellite data to the satellite interface system for transmission to the satellite. The mobile communication system further includes a display monitor comprised of tempered glass having the ability to withstand a

DETAILED DESCRIPTION It is a feature and advantage of the present invention to prevent adverse conditions experienced by a mobile communicator from causing the mobile communicator to malfunction or fail.
It is another feature and advantage of the present invention to provide information of these types of adverse conditions which are experienced by the mobile communicator in a real-time like manner.
It is another feature and advantage of the present invention to provide the ability to correct or avoid such adverse conditions before the mobile communicator can no longer operate or function properly.
It is another feature and advantage of the present invention to provide a mobile communicator that is extra durable to resist these types of adverse external conditions.
It is another feature and advantage of the present invention to provide specialized handling and safety features for the mobile communicator.
It is another feature and advantage of the present invention to permit the mobile communicator to be properly removably secured when in use.
It is another feature and advantage of the present invention to simplify the wiring configuration of the mobile communicator to inhibit adverse conditions resulting from complicated or elaborate wiring.
The present invention is based, in part, on the identification of the problem of the unusual external conditions experienced by the mobile communicator.
Accordingly, many mobile communicators have been designed in a manner which is inadequate to withstand these external conditions.
The mobile communicators have been subjected to malfunctions and complete failures as a result of not recognizing the above problems.
To achieve these and other features and advantages of the present invention, a mobile communication system is provided in a mobile satellite system.
The mobile satellite system includes a satellite communication switching office having a satellite antenna for receiving/transmitting a satellite message via a satellite from/to a vehicle using a mobile communication system, a satellite interface system, and a fleet management system including a central controller
