INTRODUCTION

RAL82 is an airborne system used to track the earth terrain and calculate the aircraft’s altitude by transmitting a radar pulse and computing the pulse echo time. Its modular architecture allows the integrity level to be adapted to the necessities of each platform. The system has been designed to meet aircrafts, helicopters and trainers’ requirements

FEATURES

Enhanced tracking performance even in case of severe manoeuvres in roll and pitch. ● Immunity to multi path ● Jamming resistance ● Interface flexibility ● Easy integration ● Easy maintenance ● Analogue signal for autopilot
