Satellite Operators Discover Fiber Optics Work Better in Space Too

In a move that will surprise absolutely no one who has ever tried to download a large file over a weak Wi-Fi connection, LatConnect 60 (LC60) has signed a deal with Transcelestial to bolt a laser communications terminal onto its SWIRSAT-1 satellite and rent time on the company's optical ground network. The contract, announced on 20 August 2026 from the glamorous locales of San Francisco and Perth, covers a terminal capable of up to 10Gbps, access to a ground network that currently has two stations live (Singapore and Spain) with five to six more promised by the end of 2026, and ongoing data transport and operations. The whole shebang is designed to get mission imagery from the spacecraft into LC60's processing environment without the usual radio frequency (RF) headaches.

“Earth-observation operators are collecting far more data than they can get to the ground,” said Dr. Mohammad Danesh, Co-Founder and CTO of Transcelestial, in a statement that could double as a thesis for why we can't have nice things. “RF downlink is spectrum-constrained, licence-heavy and expensive per gigabyte. What LatConnect 60 is buying is a high-capacity optical path plus the ground network to terminate it, bought as a service, with no spectrum licensing and no optical ground segment for them to build.” Yes, because who doesn't love skipping the part where you have to build your own ground stations and argue with regulators? Not these folks.

LC60's CEO, Venkat Pillay, chimed in with the corporate equivalent of “duh”: “For an Earth-intelligence mission, the sensor and the data path cannot be treated separately. The mission only creates value when we can move high-volume SWIR imagery from collection to users within useful delivery windows.” He added that Transcelestial's terminal will reduce the time needed to clear imagery from their SWIRSATs, which is a polite way of saying “we don't want our satellites to be the equivalent of a clogged pipe.”

This is the second Australian mission to hitch a ride on Transcelestial's optical downlink, following an integration with Gilmour Space. A Transcelestial terminal is already in orbit on the 6G StarLab mission, and the company is scaling up to produce more than 100 optical terminals a month from its own facility, so the ground network can serve multiple missions at once - because apparently, in space, sharing is caring.

LC60 is building a very high resolution Short Wave Infra Red (SWIR) satellite Earth observation constellation with a vertically integrated chain: sovereign tasking, satellite sensing, onboard processing, analytics, and direct data delivery. Their roadmap includes two SWIRSATs launching in Q1 2027 and an 18-satellite constellation by 2029. The project is backed by the Australian Space Agency and the Government of Western Australia, proving that even governments sometimes fund things that aren't giant statues.

Transcelestial will provide the high-capacity transport layer between the spacecraft and LC60's processing environment, which they describe as “equivalent to dark fibre from satellite to ground,” without the spectrum licensing RF downlink requires. LC60 retains mission tasking, data ownership, and customer-delivery control, while Transcelestial operates the transport layer. It's like renting a Ferrari instead of buying one - you get the speed without the maintenance headaches.

For those keeping score at home, a typical small-satellite X-band link runs at 100 Mbps, moving roughly 5GB in a seven-minute pass. That forces operators to compress imagery onboard, which eats power and fidelity. The same pass on Transcelestial's 1Gbps optical service moves roughly 50GB, and at 10Gbps, it's a whopping 500GB. That's a lot of cat pictures, or in this case, high-volume SWIR imagery of Earth's surface.

Optical links are also harder to intercept than RF, because the beam is narrow and directional - an interceptor would need to physically stand in the beam's path, which is not exactly a subtle operation. Plus, Transcelestial's post-quantum cryptography, in production since March 2026, adds quantum-resistant protection at the application layer. Because in the future, even quantum computers will be trying to hack your satellite photos.

Network diversity helps with availability: with optical ground stations in multiple locations, if weather closes one station, the downlink simply routes to another, or you wait for the next window. Within a pass, adaptive data rates and forward error correction raise throughput continuously as the geometry improves, rather than dropping to a fixed fallback rate. As LC60 scales to 18 satellites, the same network can absorb added missions without new ground infrastructure - a scalable dream for any bandwidth-hungry satellite operator.

Transcelestial builds laser communications hardware and operates the ground network to use it, covering satellite-to-ground downlink, inter-satellite links, and terrestrial point-to-point connectivity. With active ground stations in Singapore and Spain, 100+ terminals produced monthly, and four missions planned over the next 12 months, the company is building a constellation of LEO satellites to act as an undersea cable replacement in space. Because why lay cables on the ocean floor when you can bounce lasers off satellites? It's like Wi-Fi for the whole planet, minus the dropped connections.
