A-Series IE Orientation Explained

The following images correspond to a single system in its different positions and rotations based on how it is mounted during collection. Examples of Inertial Explorer settings are below each image.

System A

Position#1: back-of-vehicle.snoopy-a

VALUES ARE EXAMPLE ONLY.

  
  ----------GPS to IMU------------
  Rotations(degrees)
  Rot X: 0
  Rot Y: 0
  Rot Z: 0
  
  Lever arm(meters)
  Offset X: 1
  Offset Y: 1
  Offset Z: 1
  
  ----------IMU to Sensor----------
  Rotations(degrees)
  Rot X: 
  Rot Y: 
  Rot Z: 
  
  Lever arm(meters)
  Offset X: 1
  Offset Y: 1
  Offset Z: 1

Position #2: front-of-vehicle.snoopy-a

The scanner is rotated 180 degrees about the Z-axis from Position #1. VALUES ARE EXAMPLE ONLY.

  
  ----------GPS to IMU------------
  Rotations(degrees)
  Rot X: Position #1 degrees = 0
  Rot Y: Position #1 degrees = 0
  Rot Z: Position #1 degrees + 180 = 180
  
  Lever arm(meters)
  Offset X: -(Position #1 meters) = -1
  Offset Y: -(Position #1 meters) = -1
  Offset Z: Position #1 meters = 1
  
  ----------IMU to Sensor----------
  Rotations(degrees)
  Rot X: 
  Rot Y: 
  Rot Z: 
  
  Lever arm(meters)
  Offset X: -(Position #1 meters) = -1
  Offset Y: -(Position #1 meters) = -1
  Offset Z: Position #1 meters = 1

Position #3: front-of-uav.snoopy-a

The scanner has rotated -180 degrees about X axis from Position #1 (or 180 in Y from Position #2). VALUES ARE EXAMPLE ONLY.

  
  ----------GPS to IMU------------
  Rotations(degrees)
  Rot X: Position #1 - 180 = -180
  Rot Y: Position #1 = 0
  Rot Z: Position #1 = 0
  
  Lever arm(meters)
  Offset X: Variable on UAV (+right)
  Offset Y: Variable on UAV (+forward)
  Offset Z: Variable on UAV (+up)
  
  ----------IMU to Sensor----------
  Rotations(degrees)
  Rot X: 
  Rot Y: 
  Rot Z: 
  
  Lever arm(meters)
  Offset X: 1
  Offset Y: -1
  Offset Z: -1
