GoGo C1 - The replacement for Legacy ATG .

Introducing the Gogo C1:
A Solution to Bridge the Gap

With Gogo's licensed Gogo Biz air-to-ground (ATG) network LTE migration in May 2026, legacy ATG systems (ATG 1000/2000/4000/5000) are now obsolete resulting in disrupted inflight internet connectivity if not addressed.

This upgrade is part of Gogo's broader push toward LTE and, eventually, 5G technologies which benefits include improved bandwidth and performance.

The Legacy ATG Shutdown

The Gogo C1 is designed specifically as a transitional solution for operators not ready for the jump to AVANCE. Some key features & benefits include:

  • Fit & Form Replacement: A straightforward LRU swap that reuses your existing ATG antennas, cabling, trays, and routers
  • Maintains Connectivity: Stay online throughout the LTE transition while covering the contiguous U.S. as well as parts of Canada & Alaska
  • Performance & Service Plans: Service comparable to your current ATG system under existing Gogo Business Aviation plans

The C1 is designed as a bridge-the-gap product enabling continued connectivity as customers prepare for AVANCE without redundant downtime or infrastructure.
