Lab 3: Land Navigation (2)

Dead Reckoning
• Dead Reckoning is the process of estimating
current position based upon a previously
determined position and advancing that
position based upon known or estimated
speeds over elapsed time (distance travelled),
and course (direction).
What you are going to do in this lab?
Step 1: Find a route between the start point and end
point. (The route should have at least four legs).
Step 2: Measure the distance and azimuth of each
leg.
Step 3: Measure the average length of your pace.
Step 4: Calculate the number of paces for each leg.
Step 5: Follow your route and see if you can get to
your destination.
Step 1: Find the route
True North
MN
Step 2: Measure distance and
azimuth
Just like what you did in last lab.
Step 3: measure the length of your
pace
• There is a start line near Ellison Hall, and an
end line near Coral Tree Cafe. The distance
between the two lines is 100 meters.
• Start from the Ellison Hall, and count the
number of the paces (N1) you need to get to
the end line. Then go back to Ellison Hall, and
also count the number of the paces (N2).
• Your average pace length is 200/(N1+N2).
Step 4: Calculate the number of
pace you need for each leg
• The number of pace you need for one leg is:
N = distance / (average pace length)
Step 5: Test your route
• Go to the start point, follow your route
exactly, and see if you can arrive at your
destination.
Assignment
• Finish Lab 3.
• Deadline: next Thursday (Oct. 27th)
• After finishing your work, come back to Star
Lab and return the compass.
