ABSTRACT
In the present time the field of navigation is undergoing a
revolutionary development. There are three major technology
aspects that lead to this leap in performance of todays navigation
systems:
- the introduction of satellite navigation (GPS/GLONASS)
- the development of a new generation of inertial sensors
(e.g. sensors on the chip)
- the increased computer capabilities that allow complex
real time calculations
Especially in airborne applications the new technologies will lead
to systems that can achieve centimetre accuracy in all three
dimensions, in all phases of flight at very low prices compared to
todays avionic equipment.
The Institute for Flight Guidance from the Technical University of
Braunschweig operates a twin engined research aircraft that is
equipped with a satellite based navigation system. The paper will
present the basic structure of this integrated navigation system
and give examples of various applications of the system and show
the achieved performance. Special emphasis will be given to the
least results in long range differential (over 400km range)
experiments and the possibilities to use GLONASS, the Russian
counterpart to GPS. The Institute for Flight Guidance is also
doing research on new, low cost inertial sensor packages that are
based on gyro on the chip technology. By error modelling and
inflight calibration techniques it is planned to significantly
improve the performance of this sensor class. The test philosophy
and first test results will be presented in the paper.
