1 Introduction
Flarm is a collision avoidance system developed by Flarm Technologies from Switzerland. LX Navigation and Flarm
Technologies signed a contract under which LX Navigation got rights to integrate Flarm technology into LX Navigation
products.
A Flarm module consists of following main parts.
• GPS receiver
• Microcontroller unit
• Radio Transceiver
• Pressure altimeter
• Flarm external indicator
The GPS receiver defines position of the glider, the microcontroller is responsible for collision prediction calculations
and the transceiver is sending and receiving data.
Both units use the same electronic and are mechanically nearly identical. The only difference is power and GPS antenna
connection. Red Box is a completely stand alone solution and LX 5000 interface uses LX 5000 485 bus for power.
Already installed LX 5000 GPS antenna will serve both units.
