INS take Gravity, Earth Rotation and Coriolis into account

⇒ INS take Gravity, Earth Rotation and Coriolis into account

Inertial Navigation Systems (INS) have to take the Gravity Vector g, Earth Rotation Rate ω and the Coriolis Effect into account to be able to correctly calculate the movement and orientation of the aircraft over the globe without any reference to the outside.

General description of INS: Definition, Alignment, Technology, Accuracy and Limitations.

  • Alignment uses earth's rotation and gravity to find latitude and true north
  • Influence of earth's rotation and Coriolis effects on the accuracy of the INS.

Navstar GPS User Equipment Introduction by United States Coast Guard
The Navstar Global Positioning System (GPS) is a space-based radio-positioning and timetransfer system. GPS provides accurate position, velocity, and time information to an unlimited number of suitably equipped ground, sea, air and space users.

Navstar GPS Space Segment/Navigation User Interface, IS-GPS-200 by GPS.GOV
This Interface Specification (IS) defines the requirements related to the interface between the Space Segment (SS) of the Global Positioning System (GPS) and the navigation User Segment (US) of the GPS for radio frequency (RF) link 1 (L1) and link 2 (L2).

Global Positioning System; Wikipedia
The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information.

IRS Align Mode - Carefully Measuring Earth's Rotation

⇒ www.youtube.com

For several decades, long-range aircraft have used Inertial Navigation Systems/Inertial Reference Systems as sources for position information and as the primary sources for orientation information (pitch/bank/yaw/heading).

This video demonstrates the alignment process of a Honeywell IRS as it carefully measures the slow rotation of the earth to determine the aircraft's latitude and direction to the geographic north pole. The IRS uses Earth rotation to calculate an accurate latitude which it will use to cross-check the initial position that is supplied during the align mode for reasonableness.

WGS84 Earth model, Accuracy and Role in Aviation

The World Geodetic System WGS84 is the Globe Model implemented in GPS and is used not only by Google Earth and other map applications, but is also the model used for flight planing and aircraft navigation. It has cm accuracy worldwide. Using Wide Area Augmentation System WAAS it is used to fly thousands of km, even without visibility to the ground, to find the destination runway to m accurcy everywhere on earth.

I show how GPS and the WGS84 model is used in daily flight planing and navigation.
