We recommend and follow a systems approach and careful program management process in defining needs and converting them into viable and financially-attractive systems. Assuming that one starts from a position of zero, the challenge of creating and applying satellite resources is a matter of figuring out:
- What is needed – content, data, or IT applications?
- Where is it needed – domestic, regional or international?
- What is the appropriate architecture and design – constellation and gateway approach, interface with terrestrial networks, etc.?
- What are the technology options – frequencies, use of optical inter-satellite links, gateway design, etc.?
- How are requirements flowed-down to the overall satellite and to each of its subsystems – make versus buy?
- How will the satellite construction be managed to stay within its schedule and monetary constraints – in house or contracted resources?
- How should the network be implemented and how should it be managed – internally, turn-key or subcontracted?
- What is the appropriate level of security – how can cyber security be designed into the system to preclude compromise?
Added to this are other related questions, such as:
- What are the most attractive options in the space segment as to satellite design and operation?
- What’s the budget – capital and operating?
- Who will do the work – internal or external resources?
- How should the contract and supporting documentation be structured?
- How much should be outsourced and who can do it?
- How much excess capacity should be available for the future?
- What standards are available – user interface or internal to network?
- What steps are desirable to assure a reliable network or application?
- How will the network be managed – is the organization ready now?
- What risks are involved in the technology or operation plan?
