Quick Start Guide: AeroPoint Placement


This lesson provides some guidelines for placing AeroPoints in your survey area. Incorrect placement can lead to inaccurate GNSS positioning of the AeroPoint. To avoid this, please follow the steps for correct placement and take note of the examples of poor placement.

Tips For AeroPoint Placement

To obtain an accurate positioning of AeroPoint’s location, the following criteria must be met: 

  • A clear view of the sky in all directions. Avoid power lines, walls, machinery, vehicles, and trees.

  • Placed on a relatively flat surface (maximum 20° from horizontal).
  • Remain undisturbed during data capture.

Correct AeroPoint Placement

Example #1

AeroPoint is placed on a flat surface with no obstruction from nearby objects.

The AeroPoint has been placed on a flat surface far enough away from vegetation. Although vegetation is nearby, it does not obstruct the AeroPoint's clear view of the sky.

 

Example #2

AeroPoint is placed in a clearing with no obstructions from nearby objects.

The AeroPoint is placed in the center of a clearing to avoid potential obstruction from the windrow to the north. The vehicle has been parked far enough from the  AeroPoint to avoid potential interference.

Example #3 

AeroPoint is placed in the center of a clearing, away from vegetation and bodies of water.

The AeroPoint has been placed in the center of a clearing to avoid potential obstruction from vegetation and interference from nearby metal boats. The AeroPoint is also a significant distance from the nearby ocean to avoid potential signal reflections.

Poor AeroPoint Placement

If AeroPoints are positioned poorly, it can obstruct or interfere with the signals from the GPS satellite constellations that are required to accurately determine its position. 

Examples of poor placement include: 

  • Next to water (signal reflection off the surface), 
  • Underneath, on top of, or near metal structures (signal interference),
  • AeroPoint upside-down (signal interference),
  • Underneath power lines (signal interference),
  • Next to trees and buildings (signal obstruction) and
  • In deep grass or shrub (poor indication of the surface).

Example #1

Placing AeroPoints near metal structures can cause signal obstruction and interference.

Placing an AeroPoint next to a vehicle can cause signal interference with the AeroPoint's antenna. It also blocks the AeroPoint's clear view of the sky.

Example #2

Placing the AeroPoint next to tall trees can cause signal obstruction.

The AeroPoint is placed beside a large stand of trees. This causes satellite obstruction for approximately half of the AeroPoint's clear view of the sky.

Example #3

Next to a building and under power lines causes signal obstruction and interference. 

The AeroPoint was placed directly adjacent to a portable building. This causes satellite obstruction for approximately half of its clear view of the sky. In addition, the metal building and overhead power lines cause signal interference from the GPS antenna.
