Strategic Planning

• February 2004 AMSAT began a new round of
  strategic planning.
• To be done by the board members, assisted by a
  few officers and advisors and led by an outside
  facilitator.
• Discovery process, the State Of The World.
• Decision stage, AMSAT in 45 Seconds.
• Ten Stakeholder Questions Who are you? What do
  you do? Who will care? Why will they care? How
  many will care? How do you get to those who do?
  How will you make money? How are you unique and
  how will you defend your space? Do you have the
  team to pull it off? How much money do you need
  and where does it take you?
• Results were the Mission and Vision statements
• Biweekly teleconferences to work on the action
  items.

5
Tactical Planning

• It is the responsibility of AMSATs officers to
  implement the Boards strategic planning
  directives.
• In October 2004 we changed AMSATs executive
  organization
• Fewer Officers and a new emphasis on teamwork and
  cooperation, not hierarchical reporting
  responsibilities.
• President (Richard Hambly W2GPS)
• Executive VP (Lee McLamb KU4OS)
• VP Operations (Mike Kingery KE4AZN)
• VP Engineering (Stan Wood WA4NFY)
• Treasurer (Gunther Meisse W8GSM)
• Corporate Secretary (Steve Diggs W4EPI)
• Manager (Martha Saragovitz)
• VP Marketing and User Services (Barry Baines
  WD4ASW)
• VP Human Spaceflight (Frank Bauer, KA3HDO).

6
Tactical Planning

• Executive VP
• Educational, industrial, governmental and
  international relations.
• VP Marketing and User Services
• Electronic communications, contests and awards,
  AMSAT News Service, sales, the AMSAT Journal,
  Field Operations and the Web site.
• VP Human Spaceflight
• This team that crosses organizational boundaries
  between AMSAT, ARRL and NASA.
• Now on the executive team, is an indication of
  the importance AMSAT places in our involvement in
  the human spaceflight program.
• AMSAT plans to be there when humans again travel
  beyond the low orbit of the International Space
  Station, perhaps to the Moon or Mars.
• Other teams are organized as in the past.

AMSATs Strategic Plan Mission Statement

• 400-500

AMSAT is a non-profit volunteer organization
which designs, builds and operates experimental
satellites and promotes space education. We
work in partnership with government, industry,
educational institutions and fellow amateur
radio societies. We encourage technical and
scientific innovation, and promote the training
and development of skilled satellite and ground
system designers and operators.

AMSATs Strategic Plan Vision Statement

• 400-500

Our Vision is to deploy high earth orbit
satellite systems that offer daily coverage by
2009 and continuous coverage by 2012. AMSAT will
continue active participation in human space
missions and support a stream of LEO satellites
developed in cooperation with the educational
community and other amateur satellite groups

Bruce Paige KK5DO working on AMSATs Strategic
Plan.

Eagle Whats Next?

• What are the Next Steps?
• Design Team to review and solicit comments on the
  specifications
• BOD reviews design and cost estimates
• Fundraising is a critical component
• Critical subsystems must begin design work now.
• Find a suitable launch (Hopefully sooner than
  2009)

22
AMSAT Needs Your Help!

• Eagle from the Users perspective
• Review the specification (see the article in the
  2004 Proceedings).
• Volunteers are needed for key leadership and
  design positions.
• AMSAT needs your financial support
• Our ability to proceed with Eagle is directly
  dependent upon how quickly funds are donated for
  the project
• Questions?
