GNSS Project Planning Toolkit: RTK Selection, CORS/Base Decisions and Survey Preparation
Use these practical tables before contacting a supplier: choose the positioning path, define the configuration, decide between network RTK and a local base station, and collect the project details that make a quotation or technical review more useful.

This toolkit is a preparation aid, not a substitute for a site survey, safety assessment or engineering design. It helps buyers and project teams send more complete information for a relevant equipment conversation.

1. RTK GNSS Receiver Selection Checklist
Choose the workflow first. The same product search can lead to a portable survey rover, a local base-rover kit, CORS/VRS infrastructure or an integrated positioning system. Each path needs different equipment, preparation and support.
| Project situation | Starting configuration path | What to confirm before comparison |
|---|---|---|
| Surveying, stakeout or GIS collection where an appropriate correction service is available. | RTK rover with controller or field software, correction access and required accessories. | Accuracy target, coordinate system, correction service, field environment and data export. |
| Project area has weak network correction coverage or requires local correction control. | Local base receiver plus rover, antenna, radio or data link and power plan. | Control point, baseline/working area, radio environment, base location and setup responsibility. |
| Reference-station, CORS or VRS deployment for multiple users or sites. | Infrastructure receiver, reference antenna, communications, power and operating workflow. | Coverage, site conditions, data output, redundancy, maintenance owner and installation access. |
| Robotics, machine control or OEM integration. | Positioning integration review covering receiver format, antenna, interfaces and correction source. | Host system, required outputs, update behavior, installation location, validation method and support scope. |

2. Configuration Template for a Clearer Equipment Request
Copy these fields into an inquiry, internal procurement brief or distributor handover. Leaving an item as “to be confirmed” is better than assuming it is included in a product package.
| Field | Information to provide | Why it matters |
|---|---|---|
| Application and task | Surveying, stakeout, GIS, monitoring, river survey, machine control, robot or CORS/VRS. | Sets the correct product and workflow path. |
| Accuracy and output | Required accuracy, coordinate system, report, CAD/GIS export or data-delivery format. | Prevents a receiver-only comparison when a full data workflow is needed. |
| Correction method | Network RTK, CORS/VRS, local base, radio, mobile data or to be confirmed. | Determines receiver, antenna, radio and communications requirements. |
| Installation and environment | Portable, fixed station, vehicle, vessel, robot or machine; note sky view, power, mounting and access constraints. | Defines hardware format, protection and commissioning planning. |
| Commercial handover | Destination country, quantity, timing, documents, training, local support and warranty questions to discuss. | Makes the quotation and delivery discussion more complete. |
3. CORS/VRS or Local RTK Base Station Decision Table
Do not select a correction method by product name alone. Use the site, coverage and operating model to decide what should be evaluated next.
Network RTK or CORS/VRS may fit when
- A compatible correction service or reference-network plan is available for the intended area.
- Teams need a multi-user or multi-site correction workflow.
- Communications, reference-station operation and service responsibilities are defined.
- The project can validate coverage, coordinate reference and operational continuity.
A local base-rover workflow may fit when
- Network correction is unavailable, unreliable or not the chosen method for the job.
- The team controls a suitable base position, antenna location, power and communications plan.
- The working area, radio/data-link conditions and setup responsibility are understood.
- The project has a field procedure for base setup, checks and handover.

4. Measurement and Survey Project Preparation Checklist
Before requesting hydrographic, monitoring, field-survey or positioning equipment, prepare the technical and commercial context below. This makes it easier to decide whether the project needs a product, a package or a broader workflow review.
Site and task
Define the work area, access, hazards, surface or water conditions, repeatability, survey object and project schedule.
Data and deliverable
State the required accuracy, coordinate system, observation or survey method, data format, report and project-owner acceptance criteria.
Equipment and people
List existing hardware, correction source, software, mounting, power, communications, operator skills and technical-support needs.

FAQ
What information should I prepare before requesting a GNSS configuration?
Prepare the application, accuracy target, correction method, country, quantity, operating environment, expected deliverable, required accessories and any integration or training needs.
How do I choose between a local RTK base station and network RTK?
Start with correction coverage, site access, working area, control-point requirements, communications, operator responsibility and long-term maintenance. Use the decision table before choosing a receiver package.
Can this toolkit replace a site survey or engineering design?
No. It is a preparation tool for a clearer equipment discussion. A project team should still validate site, safety, survey-method and engineering requirements for its own work.
