Infrastructure Stack · Layer 01
Communications & PNT
Reliable communications, positioning, navigation and timing for people, vehicles, robots and equipment.
Why it matters
The links and signals everything else depends on.
Landers need to talk to Earth and to each other. Rovers need to know where they are. Operators need a shared sense of time. On the Moon there is no GPS, no fiber and, on the far side and in polar craters, no direct line of sight to Earth.
Communications and positioning, navigation and timing (PNT) turn a collection of individual missions into a network. Every other layer of the stack inherits their limits.
Communications networks will connect assets. Navigation systems will tell those assets where they are.
Inside this layer
5 building blocks
Lunar communications networks
Shared networks that carry voice, telemetry and data between the surface, lunar orbit and Earth, instead of every mission bringing its own link.
Positioning, navigation and timing
Position, velocity and a shared lunar time reference for precision landing, surface traverse and rendezvous. A lunar equivalent of GNSS does not yet exist at scale.
Relay satellites
Orbital relays that extend coverage to the far side, the poles and permanently shadowed regions where the signal cannot reach Earth directly.
Interoperability
Common standards so hardware from many providers and nations can share the same networks.
Spectrum and network architecture
Allocation, coordination and protection of frequencies as lunar traffic multiplies, and the architecture that ties surface, orbit and ground together.
Connect the stack
Dependencies
These aren’t isolated technologies. The opportunity lies in understanding how those systems connect.

Questions we are watching
Open questions
- Who owns the relay layer, and on what terms do commercial missions get access?
- Which timing and navigation standards win, and who sets them?
- How much ground-station and relay capacity exists for the number of missions being planned?
