Gogo Upgrade or Starlink? Why some aircraft owners are choosing to upgrade their Gogo ATG system to AVANCE instead of Starlink.

If you currently have a Gogo ATG system installed on your aircraft, you might be considering an upgrade to either the AVANCE L3 or L5 system or perhaps installing Starlink. Both AVANCE and Starlink offer significant performance improvements over the legacy ATG system, but there are key differences that might make one a better choice over the other depending on your specific needs. Here’s a detailed comparison to help you make an informed decision.

December 2025 Calendar

Understanding the Upgrade Deadline for Legacy ATG Network

To continue enjoying seamless connectivity and take advantage of available rebates, upgrading from a legacy ATG system to either AVANCE L3, L5, or the forthcoming 5G system must be completed by December 2025. This deadline is crucial because the demand for upgrades will likely surge as it approaches, potentially resulting in longer downtimes and fewer available slots at service shops. The ATG legacy network will be migrated to LTE, rendering the existing ATG equipment incompatible with the new system.

AVANCE L3 and L5

Advantages

  1. Cost-Effectiveness:
    • Installation Costs: Upgrading to AVANCE L3 or L5 is generally less expensive than installing Starlink. The installation downtime ranges from 10 to 15 business days depending on the airframe, which is shorter than Starlink’s 15 to 20 business days.
    • Subscription Costs: Gogo has a variety of subscription plans designed to fit a wider range of budgets compared to Starlink’s offerings. This includes a variety of data plans to suit different usage needs.
  2. Rebate Incentives:
    • Significant rebates are available for upgrades completed by the end of 2025, reducing overall costs further.
  3. Compatibility and Weight:
    • AVANCE systems are designed to fit a wide range of airframes without significant modifications. They are lighter and require less space compared to Starlink antennas, making them a more practical option for smaller aircraft.
  4. Domestic Connectivity:
    • For flights primarily within the United States and Canada, AVANCE provides robust and reliable connectivity. The network coverage is extensive and optimized for domestic routes.
  5. Future International Capabilities:
    • When tethered to an AVANCE platform, the future integration with the Galileo satellite system will enhance international connectivity, providing global coverage and improved performance for flights outside of North America.
Starlink

Advantages

  1. Global Coverage:
    • Starlink is ideal for aircraft frequently flying international or intercontinental routes. Its satellite-based system ensures connectivity even in remote areas where terrestrial networks like Gogo might not reach.
  2. High-Speed Internet:
    • Starlink offers high-speed, low-latency internet, which is beneficial for high-bandwidth applications and streaming.
  3. Future-Proof Technology:
    • As Starlink continues to expand and improve its satellite network, the system is poised to offer even better connectivity and coverage in the future.
  4. Innovation and Cutting-Edge Technology:
    • Starlink is at the forefront of satellite internet technology, providing users with the latest advancements in global connectivity.
Considerations
  1. Installation Challenges:
    • Antenna Size and Weight: The Starlink antenna is significantly larger and heavier (around 54 pounds), which might not be suitable for smaller aircraft like the HondaJet or certain Citation models. This can impact the performance and handling of the aircraft.
    • STC Availability: Supplemental Type Certificates (STCs) for Starlink installations are still pending for many aircraft models. This uncertainty can delay installation plans.
  2. Higher Costs:
    • Installation Costs: The initial installation cost for Starlink is higher due to the complex nature of the antenna system.
    • Subscription Fees: Starlink’s subscription fees are steeper, with limited plan options that might not be cost-effective for all users. For instance, their plans include a $2,000 per month option with a data cap of 20 GB and $10,000 for unlimited data, which can be prohibitively expensive for some users.
  3. Limited Rebates and Incentives:
    • Unlike the Gogo upgrade path, there are no substantial rebates for switching to Starlink within the specified timeframe.
AVANCE L3 and L5

Advantages

  1. Cost-Effectiveness:
    • Installation Costs: Upgrading to AVANCE L3 or L5 is generally less expensive than installing Starlink. The installation downtime ranges from 10 to 15 business days depending on the airframe, which is shorter than Starlink’s 15 to 20 business days.

Something for Everyone

For most aircraft owners flying predominantly within the United States, upgrading to an AVANCE L3 or L5 system offers a more practical and economical solution compared to Starlink. The key benefits include lower installation and subscription costs, faster and easier installation, compatibility with a wider range of aircraft, and attractive rebate incentives that make the upgrade more affordable.

However, if your flights frequently take you outside the United States and you require global connectivity, Starlink might be the better option despite the higher costs and installation complexities. It’s essential to evaluate your specific needs, flight patterns, and budget when making this decision.

Whichever You Choose…Don’t Wait Too Long!

Another critical factor to consider is the availability of installation slots as the December 2025 deadline approaches. The surge in demand could mean that those who delay their decision might find it challenging to secure a shop capable of completing the upgrade in time. Missing this deadline could result in losing up to $50,000 in available rebates, making a timely decision even more crucial.

For Starlink, demand for installation is increasing daily, with lead times currently at 4-6 weeks just to receive the equipment. As more STCs are added, this demand will rise even faster, so be sure to book your installations well in advance.
