WASHINGTON - Industry executives say that as concepts such as the "space data layer" generate buzz in defense and space policy circles, companies working to build a "space internet" based on laser-connected satellites need to go beyond technological promises and demonstrate concrete use cases.
Speaking at the SmallSat Symposium in Mountain View, California, panelists said terms such as "space data layer" have become fashionable shorthand for modernization, even as end users remain focused on outcomes rather than architecture. Customers, they said, are less interested in whether data moves by radio or laser than in how it is organized, shared and exploited once it is available.
Beau Jarvis, Chief Revenue Officer of Kepler Communications, stated that despite growing market interest in optical communications, many satellite operators and payload developers struggle to implement the technology due to a lack of experience.
"Customers generally recognize the value of optical communications, but because the technology is still relatively new to most people, manufacturers often lack the necessary technical capabilities," he explained.
Kepler, headquartered in Canada, recently deployed the first batch of 10 satellites for its optical data relay constellation. These satellites are equipped with high-capacity laser terminals and onboard computing hardware, designed to enable on-orbit data processing rather than simply transmitting raw information to the ground.
Jarvis revealed that the initial satellites carried payloads from several customers to demonstrate the operational model of a space-based data network. "We have disclosed some partners, and others are yet to be announced."
One disclosed partner is the German company OroraTech, which specializes in wildfire detection using thermal infrared sensors. Jarvis stated that connecting these sensors to Kepler's optical relay network enables continuous, real-time transmission of orbital data.
"Excitingly, as the satellites connect to the network and go live, we will be able to broadcast thermal infrared data from space with zero latency," he said.
From an operational perspective, this capability will fundamentally change how space-based data is used on the ground. "For emergency responders, the ability to accurately detect and identify wildfires in real time from space is a completely new capability. This is a true space-based data layer," he added. He further explained that with computing resources distributed across the network, operators can directly deploy analytical algorithms in orbit, thereby reducing the need to transmit massive amounts of raw data and enabling space systems to shift from periodic downlink operations to continuous, networked operations.
