Ranging and positioning test of an aircraft using a geostationary satellite

Abstract

In‐the aeronautical satellite system for the air traffic control in the oceanic area, it is important to know the position of aircraft at the ground earth station. This paper describes the ranging and positioning system using two geostationary satellites (real satellite and a pseudosatellite on the ground). This system is designed to allow ranging and positioning of each aircraft every 0.6 s within the ranging and positioning accuracy of 100 m and 1 km, respectively. Experiments to estimate this system were performed using a real aircraft. Results gave better accuracy than those mentioned in the foregoing.

Differential positioning experiment using two geostationary satellites

“…It should be noted that methods described below can be also applied to an aircraft. [3]: This is the usual method for determining the position of a ship (or an aircraft) using two geostationary satellites. Two ranges between two satellites and a ship are required to determine a position in this method, where it is assumed that an altitude of a ship is known or can be obtained with other means such as an altimeter.…”

“…After the launch of the ETS-V in August 1987, the navigation experiment started. In this experiment, ranging and positioning of an aircraft were performed by using the ETS-V and a pseudosatellite on the ground [3,4]. Our system has the following characteristics.…”
