Global Positioning System

• GPS Rover Backpack
• Location/Elevation Collection

• GPS Base Station
• GPS Error Correction from Known Point

14
Global Positioning System

• GPS Antenna
• white disk is the GPS satellite antenna receiving
  signals
• black wire antenna is the radio communicating
  with Rover Backpack

• GPS receiver translates GPS satellite
  information into a useable position and issues
  correction to Rover

• The red crosses are the points that were
  surveyed. We did both sides of the road and then
  a bit at the top of the landfill. The corners
  (lowest elevations) are points we surveyed to
  show the difference in height from the paved road
  to the top.
• Below are different views.

Research Activities Since Last Board Meeting

• UCF/UF Sensor Investigation
• Monitoring of pressure transducers at NRRL Cell 2
  and 3 and the Tomoka Falls Landfill

Sensor Conclusions

• Sensors respond to wetting front arrival and
  passage
• Sensors are sensitive to changes in leachate
  characteristics.
• Use 0.5 mm diameter sand particles for optimum
  response time and sensitivity
• Provide wicking material external to sensor to
  increase responsiveness
