How to Map Satellite Telemetry Data Instructions Materials Needed
Example #1: Find the Crane's Latitude
Column A: Record the crane's exact latitude here. Column B: Find the latitude line nearest the crane, directly to the south, and record that number here. Put a transparency on top of your map. Draw a line along this latitude line. Column C: The crane is a fraction of a degree north of the line you just drew for B. As given in the satellite data, record the fraction as a decimal in this column. Column D: Measure the scale of your map for latitude. Record the scale here in mm per degree latitude. Column E: Find out how far north (in mm) the crane is located from the latitude line you drew for (B). To do this, multiply the decimal in column C by the scale of your map D and record the product here. Now draw a line this distrance north of the line you drew for (B). The crane is located on this latitude line.
Example #2: Find the Crane's Longitude
Column F: Record the crane's longitude here. Column G: Find the longitude line nearest the crane, directly to the east, and record that number here. Put the transparency back on your map. Draw a line along this longitude line. Column H: The crane is a fraction of a degree west of the line you just drew for G. As given in the satellite data, record the fraction as a decimal in this column. Column I: Measure the scale of your map for longitude. Record the scale here in mm per degree longitude. Column J: Find out how far west (in mm) the crane is located from the longitude line you drew for (G). To do this, multiply the decimal in column (H) by the scale of your map (I) and record the product here. Now draw a line this distrance west of the line you drew for (G). The crane is located on this longitude line, exactly where it intersects the latitude line. Note to Teachers National Math Standards (NCTM)
