=== Requirements on Structures ===
====Launch Vehicle Placement Requirements====The satellite is to be launched on a launch vehicle. Each launch vehicle has some specifications for different classes of satellites. The satellite structure should be able to interface with the launch vehicle and hence meet the specifications of the launch vehicle.
====Launch Loading Requirements====
The satellite is carried to its orbit by a launch vehicle in a flight lasting about 17 minutes for Low Earth Orbits. During this period, the vehicle experiences high levels of acceleration, vibrations and shocks which are transmitted to the payloads attached to the flight decks of the vehicle. Launch loads experienced include static loads, vibration loads, acoustic loads and shocks and impose certain strict requirements on the structure of the satellite. Satellite structure should be able to withstand these loads during launch. All the components should be safe and working after the launch. The loading specification for which the launch vehicle interface is tested is assumed to be the loading data for the satellite during launch.
====Transportation and Handling Requirements====
The satellite, once integrated, needs to be handled and transported to the launch site. For this purpose the structures team needs to design a handle for the satellite and a satellite box for transportation. Many factors such as electrostatic charge, vibration, contamination from humidity, pressure management, thermal control needs to be looked at. <br \>
Apart from this transportation boxes for individual components to be sent for integration at the clean room may be required.
