Version 1.1  |  Effective Date: 24/06/2026  |  Last Revised: 24/06/2026

PLEASE READ THESE TERMS AND CONDITIONS CAREFULLY BEFORE ACCESSING OR USING THE RTK.IE SERVICE. This is a legally binding agreement between you (the Customer) and Sentrinav Ltd (trading as RTK.ie). By purchasing a Subscription or Credits package, creating an account, or accessing the Service in any way, you confirm that you have read, understood, and agree to be bound by these Terms and Conditions in their entirety.

If you are accepting these Terms on behalf of a company or other legal entity, you represent and warrant that you have the authority to bind that entity, and references to "you" and "Customer" in these Terms shall refer to that entity.

If you do not agree with any part of these Terms, you must not access or use the Service.

1.  Definitions

In these Terms, the following words and expressions shall have the meanings set out below:

2.  The Service

2.1  Description

Sentrinav operates the Network across the island of Ireland and provides the Service to Customers via the NTRIP protocol over an internet connection. The Service delivers Correction Data to compatible GNSS receivers, enabling centimetre-level real-time positioning for professional surveying, construction, mapping, and related applications.

2.2  Coverage

The Service is designed to provide coverage across the island of Ireland. Coverage may vary by location due to local environmental conditions, topography, atmospheric interference, or the proximity and operational status of individual reference stations. Sentrinav does not guarantee continuous or uninterrupted coverage at any specific location.

2.3  Satellite Systems

The Service provides Correction Data for GPS, GLONASS, Galileo, and BeiDou satellite constellations. Sentrinav reserves the right to add, modify, or discontinue support for any satellite system or constellation at any time, subject to Clause 14.

2.4  Licence Grant

Subject to the Customer’s compliance with these Terms and payment of the applicable fees, Sentrinav grants the Customer a non-exclusive, non-transferable, revocable licence to access and use the Service during the Access Period solely for the Customer’s own professional positioning and surveying purposes.

3.  Access and Credentials

3.1  Issuance of Credentials

Upon activation of a Subscription or Credits package, Sentrinav will issue the Customer with Credentials. These Credentials are specific to the Customer’s account and are used to authenticate access to the Service via the NTRIP protocol.

3.2  Use of Credentials

The Customer may use the Credentials on any GNSS receiver or device for the Customer’s own use. The Customer may authorise personnel within their organisation to use the Credentials as Authorised Users. The Customer accepts sole responsibility for all use of the Service under their Credentials, whether by the Customer or any Authorised User.

3.3  Single Concurrent Connection

The Service supports one active NTRIP connection per set of Credentials at any one time. This is enforced at the infrastructure level. Attempts to establish simultaneous connections using the same Credentials will result in only one connection being maintained; the behaviour of any additional connection attempts is not guaranteed.

3.4  Confidentiality of Credentials

The Customer is responsible for maintaining the confidentiality of their Credentials. The Customer must not disclose Credentials to any third party outside their organisation, and must not share, sublicense, sell, resell, transfer, or otherwise make Credentials available to any third party for commercial gain or for use beyond the Customer’s own business operations.

3.5  Unauthorised Use

The Customer must notify Sentrinav immediately at info@rtk.ie upon becoming aware of any actual or suspected unauthorised use of their Credentials or account. Sentrinav shall not be liable for any loss or damage arising from unauthorised use of Credentials prior to such notification.

4.  Subscriptions

4.1  Nature of a Subscription

A Subscription provides the Customer with unlimited access to the Service for a fixed Subscription Period. The Subscription Period commences on the date of activation and expires at the end of the period purchased, as confirmed to the Customer by email upon activation.

4.2  No Automatic Renewal

Subscriptions do not renew automatically. Access to the Service will cease at the end of the Subscription Period unless the Customer purchases a new Subscription. It is the Customer’s responsibility to monitor the expiry of their Subscription and to renew in advance of expiry if continued access is required.

4.3  Expiry

Upon expiry of the Subscription Period, the Customer’s Credentials will be deactivated and access to the Service will cease. No refund or credit will be issued in respect of any unused portion of a Subscription.

4.4  Suspension

A suspension of the Service by Sentrinav in accordance with Clause 10 shall not extend the Subscription Period or entitle the Customer to any refund or credit, except where suspension is caused by Sentrinav’s discontinuation of the Service in accordance with Clause 10.4.

5.  Credits

5.1  Nature of Credits

Credits provide the Customer with a time-based entitlement to access the Service, measured in hours of active connection time. Credits are consumed only when the Customer is actively connected to the Service via the NTRIP protocol. Credits are additive; multiple Credits packages may be held concurrently on the same account.

5.2  Credits Expiry

All Credits packages carry a Credits Expiry Date. The Credits Expiry Date is specific to each Credits package purchased and is confirmed to the Customer at the time of purchase. Credits that have not been consumed by the Credits Expiry Date will expire automatically on that date and are forfeited without refund or credit.

5.3  Expiry Periods

The Credits Expiry Date applicable to each Credits package is confirmed to the Customer in the credentials email issued upon activation of the package. Expiry periods may vary between different Credits packages. It is the Customer’s responsibility to be aware of the Credits Expiry Date applicable to each package purchased.

5.4  No Rollover

Unused Credits do not roll over to a new Credits package, do not carry forward beyond the Credits Expiry Date, and cannot be transferred between accounts. Upon expiry, any remaining Credits balance is permanently forfeited.

5.5  No Automatic Renewal

Credits packages do not renew automatically. It is the Customer’s responsibility to monitor their Credits balance and expiry date and to purchase additional Credits as required.

6.  Fees and Payment

6.1  Fees

Fees for Subscriptions and Credits packages are as published on the Website at the time of purchase. All fees are stated exclusive of VAT and any other applicable taxes, levies, or duties, which shall be payable by the Customer in addition to the stated fee at the rate applicable at the time of purchase.

6.2  Payment

Payment is due in full at the time of purchase. Access to the Service will be activated upon receipt of cleared payment. Sentrinav reserves the right to withhold or suspend access pending receipt of payment.

6.3  Price Changes

Sentrinav reserves the right to amend its fees at any time. Any change in fees will be published on the Website and will not affect Subscriptions or Credits packages already purchased. Customers will be notified of fee changes in accordance with Clause 14 where such changes are material.

6.4  Refund Policy

Sentrinav’s refund and cancellation policy is set out in a separate Refund and Payment Policy document, available on the Website. The Refund and Payment Policy forms part of the agreement between Sentrinav and the Customer and should be read alongside these Terms.

7.  Acceptable Use

• Use the Service fraudulently or with stolen, cloned, or misappropriated credentials.

7.3  Permitted Use of Correction Data in Professional Workflows

For the avoidance of doubt, the following uses of Correction Data are expressly permitted under these Terms:

• Logging Correction Data received during a survey session for the purpose of quality assurance, audit, or post-processing verification;

• Incorporating Correction Data or derived positional outputs into survey deliverables, reports, drawings, or project files shared with the Customer’s clients;

• Using Correction Data within standard GNSS survey data collection and office processing workflows, including the exchange of project files between field and office software.

7.4  Compliance with Laws

The Customer is solely responsible for ensuring that their use of the Service complies with all applicable laws, regulations, codes of practice, and professional standards in the jurisdiction in which the Service is used. Sentrinav makes no representation that the Service is appropriate or lawful for use in any particular jurisdiction outside the island of Ireland.

8.  Customer’s Professional Responsibility

8.1  Independent Verification

The Customer is solely responsible for independently verifying the accuracy and suitability of all Correction Data and derived positional outputs before using them in any application where error could result in loss, damage, or injury. The Service provides positional information only. Sentrinav does not provide survey, engineering, or professional advice of any kind.

8.2  Professional Competence

The Customer represents and warrants that it is professionally competent in the use of GNSS equipment and correction services of the type provided by RTK.ie, and that it will apply appropriate professional judgement in assessing the accuracy, reliability, and suitability of any data derived from the Service for the Customer’s intended application.

8.3  Safety-Critical Applications

The Service is not intended for and must not be used in any safety-critical application. Safety-critical applications include, without limitation, any application where a failure of, or error in, positioning data could directly cause or contribute to death, personal injury, or significant damage to property or the environment, including but not limited to: the navigation or control of autonomous or semi-autonomous vehicles or vessels; aircraft navigation or guidance; emergency response positioning systems; and the control of unmanned aerial vehicles (drones) in any context where failure could endanger persons or property.

8.4  GNSS Receiver and Equipment

The Customer is solely responsible for the selection, maintenance, and operation of any GNSS receiver or other equipment used to access the Service. Sentrinav accepts no responsibility for the performance, accuracy, or compatibility of the Customer’s equipment.

8.5  Internet Connectivity

Access to the Service requires the Customer to have a suitable internet connection. The Customer is solely responsible for procuring and maintaining internet connectivity, and for any costs associated with data transmission. Sentrinav accepts no responsibility for the availability, quality, or cost of the Customer’s internet connection.

9.  Service Availability

9.1  Best Efforts

Sentrinav will use commercially reasonable efforts to maintain the Network in operational condition and to provide the Service on a continuous basis. However, the Service is provided on a best-efforts basis only. Sentrinav does not guarantee any minimum level of uptime, availability, accuracy, or continuity of the Service.

9.2  Planned Maintenance

Sentrinav may interrupt the Service for the purposes of planned maintenance, upgrades, or improvements to the Network. Where practicable, Sentrinav will provide advance notice of planned maintenance via the Website or by email. Planned maintenance periods shall not constitute a breach of these Terms.

9.3  Unplanned Interruptions

The Customer acknowledges that the Service may be interrupted, degraded, or made unavailable without notice due to factors including but not limited to: individual reference station outages; third-party telecommunications or internet infrastructure failures; atmospheric and ionospheric conditions; radio frequency interference, including GNSS jamming or spoofing events; power failures; and other factors beyond Sentrinav’s reasonable control.

9.4  No Liability for Interruptions

Sentrinav accepts no liability for any loss, damage, cost, or expense suffered by the Customer as a result of any interruption, degradation, or unavailability of the Service, whether planned or unplanned, except to the extent expressly provided in Clause 10.4. Interruptions to the Service shall not entitle the Customer to any refund, credit, or extension of the Access Period.

9.5  Accuracy Disclaimer

Sentrinav accepts no liability for the unavailability, inaccuracy, or incompleteness of Correction Data for any reason whatsoever. The Customer acknowledges that GNSS positioning accuracy is inherently dependent on factors outside Sentrinav’s control, including satellite geometry, atmospheric conditions, multipath effects, and the performance of the Customer’s equipment.

10.  Suspension and Termination

10.1  Suspension by Sentrinav for Misuse

Sentrinav reserves the right to immediately suspend or terminate the Customer’s access to the Service, without notice and without liability, in the event of:

• Any actual or suspected breach of these Terms, including but not limited to prohibited use under Clause 7.2;

• Any use of the Service that Sentrinav reasonably believes is fraudulent, unlawful, or harmful to the Network, the Service, or other customers;

• Any attempt to circumvent the single concurrent connection limitation or to share Credentials in breach of Clause 3.4;

• Any activity that imposes an unreasonable or disproportionate load on the Network infrastructure.

10.2  Effect of Suspension or Termination for Misuse

Where Sentrinav suspends or terminates the Customer’s access for misuse or breach of these Terms, no refund or credit shall be due to the Customer in respect of any unused Subscription Period or unexpired Credits. Sentrinav reserves the right to pursue any additional remedies available at law.

10.3  Termination by Customer

The Customer may cease using the Service at any time. Termination by the Customer does not entitle the Customer to any refund of fees paid, in accordance with Sentrinav’s Refund and Payment Policy.

10.4  Discontinuation of the Service by Sentrinav

In the event that Sentrinav permanently discontinues the Service in whole, Sentrinav will provide not less than thirty (30) days’ written notice to the Customer. In such circumstances, Sentrinav will refund to the Customer the pro-rata value of any unused Subscription Period or unexpired Credits remaining at the date of discontinuation. For the avoidance of doubt, this clause applies only to permanent discontinuation of the Service and not to planned or unplanned interruptions as described in Clause 9.

The following clauses shall survive the termination or expiry of these Terms for any reason: Clause 1 (Definitions), Clause 8 (Customer’s Professional Responsibility), Clause 11 (Intellectual Property), Clause 12 (Limitation of Liability), Clause 15 (Governing Law), and Clause 16 (General).

• Incorporate positional outputs derived from the Correction Data into survey deliverables, reports, drawings, designs, models, or project files and share such deliverables with the Customer’s clients in the normal course of the Customer’s professional business;

• Exchange project files containing derived positional data between field data collection software and office processing software as part of standard GNSS survey workflows.

11.5  Aggregated Usage Data

Sentrinav may collect, analyse, and use aggregated and anonymised data relating to the use of the Network and the Service, including connection statistics, usage patterns, and network performance metrics, for the purposes of operating, monitoring, improving, and reporting on the Service.

12.3  Liability Cap

In all events, Sentrinav’s total aggregate liability to the Customer under or in connection with these Terms, whether in contract, tort (including negligence), breach of statutory duty, or otherwise, shall not exceed the total amount paid by the Customer to Sentrinav for the specific Subscription or Credits package in respect of which the claim arises during the twelve (12) months immediately preceding the event giving rise to the claim.
