Lead proposition · pre-launch validation
Correction transport working
Public NTRIP delivery and RTCM transport are verified.
Real-rover RTK FIX verified
RTK FIX, 30-minute correction stability and deliberate hotspot-loss reconnect are verified on the current Rover.
Local-first qualification active
The current P1 gate is correction delivery without phone hotspot or external Internet. CommCore V2 production and field qualification follows.
3ntRTKNet
Pre-commercial precision-positioning infrastructure designed to keep GNSS/RTK correction under local control and reduce dependence on remote cloud and connectivity services. Public NTRIP/RTCM transport, real-rover RTK FIX, 30-minute correction stability and deliberate hotspot-loss recovery are verified. Local-first correction delivery is the active gate, followed by CommCore V2 production and field qualification. Independent absolute accuracy remains deferred until the Base GNSS antenna is installed permanently.
Target architecture
From a stable reference point to a controlled service layer.
Base stability, correction transport, observability, recovery and privacy are treated as one infrastructure system.
GNSS antennaStable point and controlled siting.
Base receiverMulti-band GNSS observations.
Edge serviceReproducible gateway runtime.
RTCM pipelineTransport and health checks.
Private casterAuthenticated mountpoints.
Approved roversMeasured fixes and evidence.
Development roadmap
Five phases, each with an evidence gate.
Target windows are planning ranges rather than launch commitments. Progress depends on measured technical and operational results.
Foundation operational
Foundation and evidence baseline
- Current Base, Rover, gateway and correction architecture selected and operating
- Multi-band GNSS Base-to-Rover correction path commissioned
- Security, privacy and public claim boundaries documented
- CT119 ingest/archive plus recovery and QC procedures established
- CommCore Web/API and Rover telemetry integration established
- Current Canon, HOWTO and rollback evidence maintained
Foundation gate: The current engineering baseline is operational. Further product claims remain evidence-gated.
Qualification active
One-base/one-rover qualification and local-first delivery
- Controlled multi-band GNSS Base and Rover path operating
- Public NTRIP/RTCM transport and real-rover RTK FIX verified
- 30-minute correction stability and deliberate hotspot-loss reconnect verified
- CommCore Rover telemetry/API/local map accepted through Web 0.1.17
- P1: prove local-first correction delivery without phone hotspot or external Internet
- P2: qualify CommCore V2 Raspberry/PoE hardware through production and field testing
Current gates: Local-first correction delivery and CommCore V2 production/field qualification. Independent absolute accuracy is deferred until the Base GNSS antenna is installed permanently with stable mount geometry and a documented antenna reference-point / reference-height method.
Controlled UK partner pilot
- Operate with known users and approved rover equipment
- Publish compatibility notes and measured limitations
- Expose only sanitised service-health information
- Introduce rate limits and credential rotation
- Exercise maintenance and incident procedures
- Measure support burden, recurring cost and pilot value
Decision gate: Representative quality evidence and a recorded go/no-go decision for each intended use case.
Regional resilient service
- Add reference stations only where measurements justify them
- Provide redundant caster and backhaul paths
- Implement UPS, surge protection and maintenance records
- Archive RINEX and quality-control evidence
- Integrate Regional Server and 3nt Telemetry Network
- Define recovery exercises and service-level options
Decision gate: Evidenced service area, funded operational ownership, tested recovery and approved production terms.
Productisation and federation
- Community or technical test access
- Regional single-base corrections
- Managed Site Base
- Private and resilient RTK services
- Regional Network RTK and RINEX products
- 3ntTrackNET, 3ntSensorNET and field-system integration
Decision gate: Expansion follows measured demand, service quality and support capacity.
Quality, security and UK readiness
A correction service must be explainable and defensible.
Measure continuously
- Base and caster uptime
- Correction age and stream latency
- Packet loss and reconnect frequency
- RTK fix rate and time-to-fix
- Coordinate stability and repeatability
- Power, backhaul and configuration changes
Protect the service
- Private or VPN-only first deployment
- Authenticated mountpoints and least privilege
- Credential rotation and revocation
- No public rover tracks or raw GGA data
- Rate limiting and reconnect-storm protection
- Response planning for spoofing and jamming
Document UK coordinates
- ETRS89 and OSGB36
- OSTN15 and OSGM15
- Ellipsoidal and orthometric heights
- Correction-source licensing boundaries
- Site, electrical and rooftop safety
Candidate use cases
- Agriculture and field operations
- Survey and geodesy workflows
- Drones and robotic systems
- Autonomous equipment
- Local infrastructure pilots
Current boundary
3ntRTKNet is in pre-launch validation. Public NTRIP/RTCM transport, real-rover RTK FIX, 30-minute correction stability and stationary sub-centimetre relative repeatability are verified on the current development system. This page does not claim a defined coverage area, guaranteed absolute centimetre accuracy, automatic failover or an SLA. Independent absolute accuracy qualification is deferred until the Base GNSS antenna is installed permanently.
Pilot collaboration
Help test the right use case.
3nt is interested in technical and site partners for controlled GNSS and RTK validation.
