ESA Livestreams the 2026 Eclipse with Peplink and Frontier IB

Live streaming an astronomical event requires a connection capable of maintaining a stable video stream throughout the entire production. Unlike a conventional broadcast, an eclipse is a once-in-a-lifetime event: there’s no second chance if the connection fails at the crucial moment. Furthermore, it’s important to note that viewers aren’t willing to miss something like this, so our partner was very clear that there was no room for error.

For Si Quiero Streaming, the challenge was to support a demanding, uninterrupted, and completely seamless live production from a remote location.

For the broadcast, Si Quiero Streaming deployed a Peplink MAX Orbit 4 to integrate four Starlink connections: two Starlink Gen 3 terminals and two Starlink Mini terminals.

The connections were combined using SpeedFusion Bandwidth Bonding, which aggregates multiple WAN links at packet level and manages them as a single logical connection.

This enabled the setup to:

• Aggregate bandwidth across all four Starlink connections.
• Distribute traffic dynamically across the available links.
• Automatically redirect traffic if one connection became unavailable.

By combining different satellite links within a single Peplink architecture, the setup could make better use of the available connectivity while reducing dependence on any individual connection.

Testing at the Javalambre Astrophysical Observatory achieved approximately 200 Mbps of upload capacity, providing the performance required for the production.

The team completed nine hours of continuous streaming during testing, including the integration of live images received from León and Palencia, with zero critical connectivity incidents affecting the production.

For Si Quiero Streaming this meant being able to approach a one-time live event with the connectivity tested and validated beforehand, without connectivity becoming a critical point of failure.
