Why can't a mining company just use GPS or Galileo for autonomous haul trucks?

Standard GPS/Galileo open-service accuracy is 3–5 m (95%), which is an order of magnitude too coarse for autonomous lane-keeping on a 30-metre-wide haul road shared by 300-tonne trucks. Companies rely on differential corrections — RTK or PPP — delivered over communication links that are privately owned and can be degraded, repriced or suspended. A sovereign correction service removes that commercial and geopolitical dependency.

What orbit and architecture makes sense for delivering RTK corrections to a mine site?

A LEO constellation at 500–600 km, broadcasting PPP-RTK corrections in L-band, delivers corrections with latency under 35 ms and good revisit geometry for mid-latitude mine sites. Microsatellites of 50–150 kg are sufficient. GEO correction broadcasts (SBAS-style) are adequate for sub-metre but cannot reliably reach the centimetre level needed for autonomous operations.

Is there a recognised international safety standard for autonomous mining vehicles?

ISO 17757:2019 is the primary international standard; it specifies risk-assessment methodology, functional safety requirements and the accuracy thresholds that autonomous earth-moving and mining machines must meet. It does not mandate a specific positioning technology, but the ≤10 cm (2σ) accuracy implied by its safety zones effectively rules out uncorrected GNSS. The standard is under periodic revision by ISO/TC 127.

How does a sovereign satellite change anything if the trucks themselves are foreign-made?

The trucks (Caterpillar, Komatsu, Hitachi) are hardware platforms; the decisive sovereign leverage lies in the positioning signal, the correction data stream and the communication uplink — all of which can be controlled domestically. A nation that owns its correction constellation can guarantee signal availability, audit the data for tampering and deny access to foreign competitors operating mines on its territory if geopolitical conditions require it.

What happens to an autonomous fleet when the GNSS correction signal is lost?

Most modern autonomous mining systems follow a 'safe stop' protocol: if correction latency exceeds a threshold (typically 5–10 seconds), trucks decelerate and halt in place. At $250,000 per hour of fleet downtime, even a 30-minute outage caused by a commercial provider's service interruption costs $125,000. Sovereign infrastructure with redundant ground uplink stations reduces this risk to near zero.

Can a country share a sovereign PNT constellation with neighbours to reduce cost?

Yes, and this is the recommended path for smaller mineral economies. A regional constellation operated under a multilateral agency — similar to how EUMETSAT operates Meteosat for European nations — can pool costs while each member retains data sovereignty through agreed access-control protocols. The ITU coordination process for shared orbital slots is well-established and need not be a barrier.

What is PPP-RTK and how does it differ from traditional RTK?

Traditional RTK requires a reference station within 20–50 km of the rover to maintain centimetre accuracy; a remote mine may need dozens of physical base stations. PPP-RTK (Precise Point Positioning with RTK-speed initialisation) uses a network of globally distributed reference stations to compute correction parameters that are broadcast via satellite, achieving centimetre accuracy anywhere in coverage without local infrastructure. Convergence time has fallen from 20+ minutes to under 2 minutes with modern algorithms.

How long does it take to build and launch a sovereign LEO correction constellation?

A minimally viable constellation of 6–8 LEO microsatellites with regional coverage can be designed, built and launched in 36–48 months using established small-satellite platforms and a commercial rideshare launcher. Full global coverage with 24–30 satellites typically requires 60–72 months from programme start. Nations should plan for an interim commercial-service bridge during the build phase, with contractual clauses that prevent the provider from withdrawing service before the sovereign system is operational.
