[edit] Scope

What is included in this lesson, what's not and why.

SAR Fundamentals Manual: Ch.13 "Navigation"
Basic SAR Skills Manual: Ch.7 "Navigation"


[edit] Prerequisites

What should students already know/have accomplished before the lesson is presented.


Prior to this lesson, students have been introduced to the following concepts:

  • map datums
    • know the difference between NAD27 and WGS84/NAD83 and can determine which one a topographic map uses
    • are able to set the map datum on their GPS
  • UTM
    • can set their GPS to display UTM
    • can read the 3 components of a UTM from it: Zone, Easting, Northing
    • can convert a 13 digit UTM to a 6 digit UTM
  • can identify the failure modes of a GPS

[edit] Objectives

At the conclusion of this lesson Students will

  • know how to read their current location on a specific model of GPS
  • choose how long to wait for their current GPS location to settle
  • build a visual/spacial sense of how the UTM grid overlays real land
  • choose appropriate direction to walk to achieve intended changes to their current UTM

Advanced students will

  • know how to enter waypoints into their GPS
  • know how to get distance and bearing from their GPS
  • for GPS's without magnetic sensors, get a sense of how far they need to travel for the GPS to know their current heading

Present Objectives


Break students up into small groups (often best for instructor to chose groups to give students opportunities to work with others)



  • Have each groups sign-out a radio, and one or more GPS (one per student if possible)
  • Assign each group a call sign
  • Do a radio test



  • Distribute GPS instructions
  • Review how to set up GPS
    • Map Datum: NAD27 vs WGS84
    • Grid system: UTM (Canada)



  • Review how to read UTM (Zone, Easting, Northing)



  • Review how to determine accuracy (e.g. 11m)
    • waiting makes more accurate



  • Distribute maps (may have been given at start of course)
  • Establish a return to class time



  • Using the answer sheet, the instructor chooses a nearby Target Letter for row ii. All the students fill it in.
  • Each group randomly chooses letters for rows iii to vi. They write them in and the instructor records them on his sheet.



  • go outside the classroom and record the Zone, Easting, Northing and Accuracy
  • Review how to compare Eastings and Northings to compare relative distance and direction



  • as a class, walk to the UTM for the Target Letter of row ii.
  • locate and go to the nearest feature.
  • record the Feature Number, Zone, Easting, Northing and Accuracy for the feature.
  • Compare accuracy of exercise sheet with current accuracy. How do the 2 errors combine?



  • break up into assigned groups and proceed to the remaining 5 Target Letters they have chosen, find the nearest feature and record the Zone, Easting, Northing and Accuracy for the feature.
  • Some groups will complete early, have them do additional targets
