Aircraft Attitude Determination Using GPS

Technology Benefits

The new UC technology provides the following benefits: Drastically improves the performance of the navigation system without requiring additional hardware and algorithm; Provides estimation of all other aircraft states, such as position, velocity, and angular rates, without the need for multiple gyros or accelerometers on board.

Technology Application

This new UC technology has applications in aircraft navigation instrumentation.

Detailed Technology Description

Scientists at the University of California have developed a new instrument that is capable of accurately estimating all aircraft states, such as position, attitude, velocity, and angular rates. This system can provide the aircraft attitude over the flight envelope and in different exogenous weather conditions by using only the input from a single GPS receiver and the aircraft dynamics.

BACKGROUND

Global Positioning System (GPS) technology has come into widespread use and is now becoming a preferred instrument for high accuracy position and velocity estimation in inertial space. However, a stand-alone GPS receiver cannot estimate the attitude of an aircraft and must be coupled with an inertial instrument or use multiple antennas to obtain this information. The result of these additions is an increased cost in hardware and complexity of the navigation system.
