The most expensive part of many space businesses is not the satellite. It is choosing space when a cheaper layer would do.
Space has extraordinary strategic value.
But from a systems-engineering & capital-allocation perspective, orbit should be treated as a scarce and expensive resource, not the default answer to every problem.
Consider communications first.
Despite the rapid growth of satellite constellations, roughly 95–99% of intercontinental internet traffic still travels through submarine fiber-optic cables.
Why? Because the #economics are overwhelming.
Modern subsea cables can carry 100+ Tbps of capacity, are upgraded by changing terminal equipment & can move data at a cost that falls to fractions of a cent per gigabyte.
Satellite systems must absorb the cost of: spacecraft manufacturing , launch , insurance , spectrum , ground gateways etc.
Satellites are indispensable for mobility and remote access, but they do not compete with fiber on bulk data economics.
The internet feels wireless. But civilization runs on glass fibers laid across the ocean floor.
The same logic applies to Earth observation.
Generating an image in orbit is only the first step. The real value chain is:
Satellite → Downlink → Ground Station → Terrestrial Fiber → Cloud Processing → Customer
In many cases, the radio link from orbit to Earth is the shortest and most expensive segment of the entire data journey. Once the image reaches the ground, it still depends on the same terrestrial and subsea infrastructure that powers the global internet.
And the economics are substantial.
A high-resolution imaging satellite mission can require tens to hundreds of millions of dollars when spacecraft, launch, and operations are included.
By contrast, High-Altitude Platform Systems (HAPS) can deliver persistent regional imagery and communications, with some platforms reportedly costing under $10 million and being recoverable, upgradeable & reusable.
For missions such as agriculture, wildfire detection, border surveillance, and disaster response, the #Stratosphere may offer better economics than orbit.
This is not an argument against satellites or for #Stratosphere platforms. It is an argument for architectural discipline.
Sometimes the answer is subsea fiber.
Sometimes it is terrestrial infrastructure.
Sometimes it is the stratosphere.
And sometimes, only space will do.
Because in engineering as in investing , the highest-return systems allocate capital to the right layer of the stack.
Space will transform the world. But the biggest winners may be those who know exactly when not to use it.
This highlights a critical but often overlooked truth: GNSS is fundamentally a timing infrastructure, not just a positioning system. The move to distribute trusted national time standards through commercial LEO PNT represents a major shift in how critical infrastructure can be accessed and maintained. As digital systems across energy, finance, telecom, and mobility become increasingly time-dependent, resilience at the timing layer becomes as important as positioning itself. A key step toward a more distributed and resilient global infrastructure.
