Spyglass

Definitions

• Elevation/Pitch angle is the angle between the horizontal line that your sight forms when you look straight and the line to some particular point above.
  In Spyglass the elevation angle is marked with Wing or Crosshair and shows how much your device is tilted back or forth. The elevation scale is calibrated with degrees and mils and is perpendicular to the horizon line.
• GPS Coordinates – geodesic latitude and longitude coordinates of your current location, expressed in degrees, minutes and seconds (depending on the chosen coordinate format) along with the corresponding hemispheres.
• 'Grid Coordinates – your current location in the coordinates of the chosen grid coordinate system (MGRS, UTM or OSGB/BNG), to which numbers and letters are assigned for use in designating a point on a gridded map.
• Vertical Speed indicator shows your current vertical speed in knots, feet per minute or metres per second, depending on your country and set-up units. The vertical speed data will appear to the left of the altitude readings for vertical speeds higher than 80fpm (0.4m/s).
• Altitude – current height above sea level.
• Locator lets you return to the actual GPS readings after manual settings.
• Azimuth Circle measures azimuths and bearings. In Spyglass the azimuth circle is graduated with degrees, mils and points of the compass (marking divisions of the four cardinal directions). The current azimuth or bearing is marked with the Bearing Arrow.
• Location Target Pointer – points in the direction of an important location or object. Starting Bearing (AR) and Ending Bearing (AR) are the augmented reality (AR)

markers, used for the visual angle measurement, performed by the Sextant tool.

• Horizon/Roll angle shows how much the device is tilted left or right.
