Aeronautical & Navigation
Radio plays a critical part in modern navigation and location
finding systems. From simple directional beams, transmitting at a
given frequency in a specific direction, through to the latest
generation of satellite navigation systems, radio provides the
essential medium.
Aegis has been involved with radionavigation and radiolocation
systems for many years, undertaking detailed technical analysis of a
variety of systems and services and working for clients such as
Eurocontrol, Inmarsat and the UK Radiocommunications Agency.
Radio Navigation
We have a comprehensive knowledge of radio navigation systems,
including directional and non-directional beacons, VHF Omni Range
systems, Distance Measuring Equipment, Ground Radar, Instrument
Landing Systems, Microwave Landing Systems (MLS), LORAN, the Global
Positioning Satellite (GPS)
system, and Europe's Global Navigation by Satellite (GNSS)
programme.
Recent work includes the management of a series of international
measurement programmes to determine the actual out-of-band
performance of MLS receivers manufactured in Europe and North
America. For an Administration, we have also simulated the
compatibility between key radio navigation systems and other
spectrum users in shared bands.
Radiolocation
An Aegis study examined the impact on radiolocation systems of
the possible relaxation or removal of the conditions imposed on the
Fixed Satellite Service operators at 13.75-14 GHz. This analysis
included the translation of the regulatory limits into separation
distances, together with detailed sensitivity analysis of the
potential impact of parameters such as propagation behaviour,
antenna height, minimum elevation angle and Earth station power
density.
