R&S®GV4000 Multi-Link Controller

High-availability ATC radio system

Key Facts

  • Level of availability meeting or exceeding that of traditional main/standby solutions
  • Reduction in the required capital investment and ongoing maintenance costs

Brief Description

One of the key factors in ensuring safety in air traffic control (ATC) applications is to provide a high level of availability for the ground-to-air communication system. The R&S®GV4000 multi-link controller was developed to achieve this goal.

Features

  • Increase in radio channel availability
  • Reduction in system costs and rack space
  • Flexible integration into existing ATC systems

Key Facts

  • Level of availability meeting or exceeding that of traditional main/standby solutions
  • Reduction in the required capital investment and ongoing maintenance costs
  • Less space required at each radio site
  • Flexible approach for site-specific solutions

Brief Description

One of the key factors in ensuring safety in air traffic control (ATC) applications is to provide a high level of availability for the ground-to-air communication system. The R&S®GV4000 multi-link controller was developed to achieve this goal. It provides n+m redundancy for R&S®Series4200 radios, which ensures higher availability levels at lower costs compared to the traditional 1+1 redundancy.

In the past, most ATC systems used 1+1 redundancy, where each main unit had a dedicated backup unit. Today, more and more ATC authorities are employing systems with n+m redundancy, where n main units operate with m non-dedicated backup units.

The R&S®GV4000 controls the status of up to 16 main radios and two backup radios. If a radio failure occurs in any of the 16 main radios, the R&S®GV4000 automatically switches over to one of the two standby radios. Detailed mathematical calculations show that n+m redundancy can reduce system downtime by a factor of up to six compared to standard 1+1 redundancy. The results of these calculations have been confirmed through years of field experience with systems using the R&S®GV4000 in n+m applications.

The use of n+m redundancy significantly reduces the number of radios needed. As a result, considerably less space is required at each radio site, and procurement and operating costs are lower. No modifications to the voice communication switch are needed to implement n+m redundancy with the R&S®GV4000 in existing ATC systems.
