Spectrum

One frequency operation    

• • Requires only 8MHz bandwidth and operates on frequencies not used by DME due to SSR frequency protection
• • Opportunity to release a significant part of the L-Band currently used by DME/TACAN

Less spectrum load

• • Predominantly passive operation of the aircraft system
• • Mode S and Phase Overlay provide three times more data content within regular transmissions
• • Broadcast procedure allows unlimited number of participants 

Provides a safe, extended, more flexible and more efficient use of today's L-Band applications

Enables possibilities for rearrangement or defragmentation of the L-Band and the reduction of 1030/1090 MHz spectrum load by rearrangement of services

Mode N is the only L-Band A-PNT system which releases spectrum within the band
