WebSep 29, 2024 · To make this sensor data usable, we need to convert the recorded values into a global, Earth coordinate frame, also known as NED (North-East-Down) or ENU (East-North-Up). This requires knowing the orientation of the phone in space which can be calculated using other IMU (Inertial Measurement Unit) sensors such as the … These frames are location dependent. For movements around the globe, like air or sea navigation, the frames are defined as tangent to the lines of geographical coordinates: East-West tangent to parallels,North-South tangent to meridians, andUp-Down in the direction normal to the oblate spheroid used as … See more Local tangent plane coordinates (LTP), also known as local ellipsoidal system, local geodetic coordinate system, or local vertical, local horizontal coordinates (LVLH), are a spatial reference system based on the See more In many targeting and tracking applications the local East, North, Up (ENU) Cartesian coordinate system is far more intuitive and … See more • Axes conventions • Figure of Earth • Horizontal coordinate system • Geodetic coordinates See more In an airplane, most objects of interest are below the aircraft, so it is sensible to define down as a positive number. The North, East, Down (NED) coordinates allow this as an alternative to the ENU. By convention, the north axis is labeled $${\displaystyle x'}$$, … See more

The Earth rotates to the east (the direction of the sunrise!). This is counter-clockwise when viewed from the north pole down, so the Earth's angular velocity vector \vec {\Omega}_E ΩE points up at the north pole.
