Navigation Through Space

• An SJS Craft journey to the Moon

The SJS Journey

Date and Time

• Date leaving- Tuesday May 5th
• Leaving time- Around the time of 400 P.M.
• Date of Arrival- Saturday May 9th
• Time of Arrival- Around the time of 400 P.M.
• Part of moon we are landing on- North Pole
• Duration of Journey- About 4 to 5days.

Description of route and orbital paths

• We plan to launch the spacecraft 3 days after
  the Waxing Gibbous moon begins. It will then take
  it approximately 4 days to reach the North Pole
  of the moon. By that time it will be a Full Moon,
  and the North Pole of the moon would be facing
  earth. When we land on the moon it would be about
  400 P.M. that evening (on our side) on Earth.
• The path of the spacecraft would be curved
  going half way around the Earth then towards the
  path of the moon, until both the moon and the
  spacecraft meets on the Full Moon stage.

Methods of control and tracking

• We would be using the sextant, to see how far
  we are from the moon. The sextant would help
  because it would help us measure the angle in
  which the spacecraft has to make to get onto
  course. The time piece to measure how much time
  passed. This would help because it would help us
  make sure we are on time. A star chart and star
  tracker will help us see how far the craft is
  form the moon and its position with the stars.
  These would help because we would be able to
  determine the distance. The Gyroscope to help
  maintain or measure our position in space this
  would also measure the angle of the space craft
  and the moon. We would be doing this all from the
  base. The satellites would help us by giving us a
  picture of where the spacecraft is and how it
  looks. The small camera in front of it would help
  us too.

Methods of guidance and navigation

• We have to use a gyroscope and connect it to a
  GSN to control the flaps to help us control the
  spacecraft with solar winds. Also you would need
  to use a star tracker. This is used with the
  pictures from the satellites and we can compare
  the distance of the two objects. Using this tells
  where we are in relation to other stars, which
  would allow us to keep track of the spacecraft.
  The satellites will also help us in this
  situation, with the pictures they take. All of
  this we would be using on the base and control it
  from there.

Navigation Instruments

• Sextant
• Star chart
• Timepiece
• Satellites
• Accelerometers
• Rocket
• Star tracker
• Gyroscope

Description and how they would help

• A rocket- A rocket with stability and control
  functions is the most important.
• Gyroscope- is a device used for maintaining or
  measuring our position. Gyroscopes measure the
  angular velocity of the system in the inertial
  reference frame.
• Accelerometers-measure the linear acceleration of
  the system in the inertial reference frame. This
  works when the acceleration of the spacecraft
  decrees as it goes father and farther away from
  earth because of the gravity pulling it back.

• Sextant- is a navigational instrument for
  measuring the angle between objects.
• Timepiece- A timepiece is a device to measure
  time. It would measure how much time has pass to
  see if we are on schedule.
• Star Chart- To navigate to the moon with star
  navigation.
• Star Tracker- is a navigational device which
  measures the positions of stars.
• Other satellites- we would use the other
  satellites to show us images of the spacecraft
  distance form the moon.
