List of significant parts....

In trying to determine the scope of a Nano sat launcher project I generated the following list or physical hardware. There is an equivalent scope of work for Ground support, Software, Logistics, Regulatory issues etc...

1. Nose cone/aero shell
1. Aero shell separation system
2. Nano sat mount
1. Nano Sat ejection system.

3. Avionics:
1. GPS/ MEMS IMU Integrated system
2. Avionics control
3. Telemetry system
4. Battery System

4. Third Stage
1. Tanks (assuming tanks are the structure)
2. Valves and Actuators
3. Pressurization System
4. Motor
5. Motor Thrust transfer structure
6. TVC Actuators.
7. Separation mechanism
8. Fill and Drain Umbilical system.
9. Roll Control TVC

5. Second Stage
1. Third Stage Support Structure
2. Battery for second stage actuators.
3. Tanks (assuming tanks are the structure)
4. Valves and Actuators
5. Pressurization System
6. TVC Actuators.
7. Motor
8. Motor Thrust transfer structure
9. Separation mechanism
10. Fill and Drain Umbilical system.

6. First Stage
1. 2nd Stage Support Structure
2. Battery for first stage actuators.
3. Tanks (assuming tanks are the structure)
4. Valves and Actuators
5. Pressurization System
6. TVC Actuators.
7. Motor
8. Motor Thrust transfer structure
