Consultancy

We built a nationwide RTK network. Now we'll help you build yours.

Sentrinav provides vendor-neutral GNSS consulting to infrastructure projects, government bodies, and network operators worldwide — from initial feasibility through to full network operations. We advise on design, procurement, QA, and resilience without selling hardware or taking supplier margins.

Sentrinav operates RTK.ie, Ireland’s nationwide CORS network of 30 reference stations. We consult from first-hand operational experience, not theory. 

Most GNSS advice comes with a price list attached.

Our independence allows us to focus on what matters most: selecting the right technology, securing the best value, and delivering successful project outcomes.

Supplier Relationships

Sentrinav has working relationships with leading GNSS equipment manufacturers — and uses that knowledge to negotiate better terms for clients, not to earn margin.

No Resale Liability

We specify and advise on procurement without acting as a middleman. Clients own their supplier relationships and warranties directly.

Outcome-Aligned

Our fee is tied to your project outcome, not what equipment you buy.

What we do

1. Network Design & Feasibility

From blank map to station architecture — before you spend a euro on hardware.

  • Coverage modelling and redundancy planning for your geography
  • Site selection criteria and exclusion zone assessment
  • Network architecture: single-base, multi-base, VRS, and MAC configurations

2. Procurement Advisory

Vendor-neutral specification and supplier negotiation — we don’t resell.

  • Receiver, antenna, and network software specification
  • Supplier shortlisting and price negotiation support
  • Tender documentation and technical evaluation criteria

3. Accuracy Assessment & QA

Independent audit of existing GNSS setups — whether you built them or inherited them.

  • Performance benchmarking against national and international standards
  • Identification of coverage gaps, multipath issues, and baseline limitations
  • Remediation recommendations with implementation roadmap

4. Network Operations & Maintenance Consulting

We’ve operated a national CORS network for years. We know what breaks, and when.

  • Staffing and monitoring workflow design
  • SLA definition and KPI framework
  • Preventative maintenance schedules and hardware lifecycle planning

5. GNSS Interference & Resilience

Jamming and spoofing are no longer rare events. Is your network ready?

  • Interference risk assessment for your operating environment
  • Detection architecture design and technology selection
  • Alerting, reporting, and incident response planning

Who We work With

Built for clients who take positioning seriously.

1. Infrastructure & utilities

Contractors and project managers on roads, rail, energy, and water schemes who need reliable, auditable positioning across large or complex sites — where national correction networks are absent, inadequate, or unavailable.

2. Government & mapping bodies

National mapping agencies, land registries, and agricultural departments requiring independent advice on CORS network strategy, accuracy standards, or existing infrastructure assessment.

3. Agricultural & land management

Precision farming operators and land management organisations looking to deploy RTK access for soil mapping, boundary survey, and area measurement — particularly in regions where commercial correction services do not yet exist.

4. Network operators & utilities

Positioning service providers, utilities, and survey authorities in Africa, South America, Europe, and Asia who are building or upgrading GNSS infrastructure and need experienced, independent guidance from people who have done it.

Why Sentrinav

Sentrinav designed, deployed, and operates RTK.ie — a nationwide CORS network of over 30 continuously operating reference stations covering the island of Ireland. Built from scratch. Running 24/7. A working proof of what we advise others to build.

Our advice is vendor-neutral. We have no hardware to sell and no supplier agreements to protect. Clients own their supplier relationships and warranties directly — our fee is aligned with your outcome, not your purchase order.

We work across the full lifecycle — from early feasibility through procurement, commissioning, and long-term operations — so advice at each stage is informed by what comes next.
