<p>ABSTRACT This invention presents a module employing a novel method to track aircraft manually by controlling base station telemetry antenna efficiently to avoid complete RF link loss between aircraft and telemetry base station. The module consists of Input data module [100], Processing & decision making module [101] and Display module [102]. Input data module consists of Telemetry ground station reception units, it will give online aircraft parameters from INGPS or DGPS installed on the aircraft. This module will get continuous aircraft data, If RF link is stabilized between aircraft & telemetry base station. Processing & Decision making module is heart of the system, it consist of data processing sub module [103], stored aircraft database sub module [104], base station information sub module [105] and decision making sub modules sub module [106]. This module receives aircraft parameters (raw value) from input data module and converts to engineering value. Stored aircraft database consist of latest 1 minute online aircraft parameters. Base station information having fixed telemetry base station data i.e base station position (Lat, Long & altitude), base station antenna limitation i.e range, azimuth & elevation movement etc. If RF communication broken between aircraft and telemetry base station, decision making module will take data (aircraft parameters i.e lat, long, altitude, speed, pitch, heading etc) from stored aircraft data base and compute aircraft position by approximation method. It computes required azimuth and elevation angle based on stored aircraft data base, base station information and data processing block. Display block provides real time as well as expected data on manual tracking GUI. It also provides real time aircraft movement on manual tracking GUI.</p> |
