Attitude provides information about an object's orientation with respect to the local level frame (horizontal plane) and true north. GNSS attitude solutions typically consist of three components: roll, pitch and yaw.

The easiest way to understand what we mean by attitude is to consider a plane with three linear axis running through it:

  • Wing up/down = Roll
  • Nose up/down = Pitch
  • Nose left/right = heading/yaw/azimuth


Angular measurement on the horizontal plane, with respect to true north, is referred to as yaw. Yaw is also known as azimuth or heading. The angular measurement on the vertical plane, with respect to the local level frame, is computed as pitch or roll.

Attitude measurements are important for precise positioning in many applications including:

Mobile Mapping

  • Photogrammetry or scanning

Airborne Reconnaissance

  • Pointing of cameras to a specific location on the ground

Helicopter navigation

  • Where the nose is pointing, not how the helicopter is tracking over ground

Motion compensation applications

  • Ensure airborne mapping camera points vertically to the ground
  • Ensure marine mapping is not distorted by wave movement



  • Real time and post-mission processed attitude solutions
  • GPS/GNSS standalone systems and GNSS/INS systems available
  • User customizable output orientation frame
  • Output available in different formats
