4G/Satellite Connectivity Update

June 2018

By April 2018, Duncan Aviation’s avionics teams and Engineering and Certification experts had completed numerous STCs (Supplemental Type Certificates) and have several more in work for the Gogo Business Aviation AVANCE L5 Wi-Fi system for the following aircraft:

  • Gulfstream GIV (G300, G400)
  • Gulfstream GIV-X (G350, G450)
  • Falcon 2000
  • Falcon 2000 EX (EASy, DX, LX, LX5, S)
  • Falcon 900
  • Falcon 900EX (EASy, LX, DX)
  • Challenger 300/350
  • Challenger 605 (601-3A, 601-3R, 604, 605, 650)
  • Global Express (XRS, 6000)
  • Global 5000

These STCs are all for full equipment installation and approval of the WLAN (Wireless Local Area Network), allowing passengers to take advantage of connectivity speeds on Gogo Biz’s new 4G network and have a system that will grow with their aircraft in the future. This ATG (air-to-ground) network has been connecting thousands of business aviation customers for years.

For every STC Duncan Aviation has developed, we will apply for Transport Canada approval.

Currently, the only 4G ATG network for aviation is the Gogo Biz network, and it’s available to aircraft flying above 10,000 feet. Start-up SmartSky received approval for its 4G network and PMA (Parts Manufacturer Approval) authorization. SmartSky intends to deploy its new 4G network throughout 2018. 

Gogo recently introduced its AVANCE L3 product line for turboprops to mid-sized jets. AVANCE L3 equipment uses the Gogo Biz 3G network throughout the continental United States, including Alaska, and into parts of Canada. 

The Gogo and SmartSky 4G ATG networks are strictly terrestrial-based for North America, so for global travel look to a satellite-based system. KU- and KA-based systems, like Honeywell’s JetWave, feature nearly worldwide, high-speed internet connectivity. Gogo recently announced plans for its own second-generation KU network, so look for more information about that later in 2018.
