Horizontal and vertical accuracy specifications
Convergence time requirements
Performance in various atmospheric conditions
Multi-constellation GNSS support

3. Communication Options

Modern RTK services offer multiple communication methods, each with distinct advantages:

Cellular/Internet

High reliability, wide coverage, easy setup

Radio

No ongoing costs, works in remote areas

Satellite

Global coverage, premium pricing

Key Questions to Ask Providers

Service Reliability

• What is your guaranteed uptime percentage?
• How do you handle service interruptions?
• What redundancy measures are in place?

Technical Support

• What support hours do you offer?
• How quickly do you respond to technical issues?
• Do you provide on-site support if needed?

Pricing and Contracts

• What are your subscription options and pricing tiers?
• Are there setup fees or equipment costs?
• What are the contract terms and cancellation policies?

Future-Proofing

• How do you handle technology upgrades?
• What new features are in development?
• How do you adapt to changing GNSS constellations?

Evaluation Checklist

Before Making Your Decision:

Request a trial period or demo to test service quality
Verify coverage in all your operational areas
Check references from similar projects or industries
Compare total cost of ownership, not just subscription fees
Ensure compatibility with your existing equipment
Understand the service level agreement (SLA) terms

Red Flags to Avoid

• Providers who can’t provide specific accuracy guarantees
• Services with frequent unexplained outages
• Lack of 24/7 technical support for critical applications
• Providers reluctant to offer trial periods
• Hidden fees or unclear pricing structures
• Outdated technology with no upgrade path

Making the Final Decision

The best RTK service provider balances technical capabilities, reliability, support quality, and cost-effectiveness. Don’t choose based solely on price—consider the total value proposition and long-term partnership potential.

Remember that switching RTK providers later can be costly and disruptive. Take time to thoroughly evaluate your options and choose a provider that can grow with your needs.
