📖 Learn how PPP works and why it matters in 2026.

BD-PPP & Galileo HAS: The Future of High-Accuracy GNSS Positioning Without RTK

Updated for modern GNSS users | Ideal for surveying, mapping & geospatial professionals

Introduction: Why High-Accuracy GNSS No Longer Depends on RTK Alone

For years, RTK (Real-Time Kinematic) technology has been the gold standard for centimeter-level GNSS accuracy. However, RTK requires base stations, correction networks, and uninterrupted communication links—making it expensive and unreliable in remote or challenging environments.

This is where Precise Point Positioning (PPP) steps in.

With the arrival of BD-PPP (BeiDou PPP) and Galileo HAS (High Accuracy Service), GNSS users can now achieve sub-meter to decimeter-level accuracy globally—without RTK infrastructure.

In this blog, we explain:

What BD-PPP and Galileo HAS are

How they work

Accuracy and convergence comparison

Why they matter for modern GNSS operations

What Is Precise Point Positioning (PPP)?

Precise Point Positioning (PPP) is a GNSS technique that delivers high-precision results using a single receiver, without requiring a nearby base station.

Key Advantages of PPP

No CORS or base station required

Works globally

Lower operational cost

Ideal for remote and mobile operations

Increasingly faster convergence with modern satellites

Earlier, PPP was considered slow. Today, with improved satellite constellations and advanced error modeling, PPP accuracy and convergence rival RTK in many applications.

How Modern PPP Technology Achieves High Accuracy

Modern PPP systems use:

Multi-constellation GNSS (BDS, Galileo, GPS)

Multi-frequency observations

Precise satellite orbit & clock corrections

Advanced ionospheric and tropospheric models

What This Means for Users

Up to 50% faster convergence

Faster re-convergence after signal loss

Stable positioning in dynamic environments

Reliable results without network dependency

BD-PPP (BeiDou Precise Point Positioning) Explained

BD-PPP is a free PPP service broadcast by the BeiDou-3 satellite constellation.

BD-PPP Performance

Coverage: China & surrounding regions

Convergence Time: 10–15 minutes

Accuracy: Sub-meter level

Cost: Free (broadcast correction)

Best Use Cases

Regional surveying

Infrastructure projects

Agriculture & mapping

Backup when RTK fails

Galileo HAS (High Accuracy Service): Global PPP at Decimeter Level

Galileo HAS is Europe’s official high-accuracy GNSS service, broadcast via Galileo E6-B signals.

Galileo HAS Accuracy & Convergence

Within Europe

Horizontal accuracy: < 20 cm

Vertical accuracy: < 40 cm

Convergence: < 100 seconds

Global Coverage

Horizontal accuracy: < 20 cm

Vertical accuracy: < 40 cm

Convergence: < 300 seconds

Why Galileo HAS Is a Game-Changer

Global coverage

Free broadcast corrections

No internet or radio required

Ideal for international & mobile GNSS users

PPP-RTK: The Best of Both Worlds

Modern GNSS receivers now support PPP-RTK hybrid technology, allowing seamless switching between modes.

How PPP-RTK Helps

RTK accelerates PPP convergence

PPP maintains accuracy when RTK drops

No work stoppage during signal loss

Ideal for urban, forest, or radio-interference areas

This ensures continuous high-precision positioning, even in unstable environments.

How to Use PPP in Real-World Operations
Without Differential Corrections

Enable BDS PPP or Galileo HAS in receiver settings

Place receiver in open sky

Wait for convergence (10–20 minutes)

Start work once PPP FIXED status appears

With RTK Corrections

Operate normally using RTK

If corrections fail, system automatically switches to PPP

Work continues without interruption

⚠️ Tip: Continuous satellite visibility ensures faster convergence and stability.

Why BD-PPP & Galileo HAS Matter in 2025 and Beyond

GNSS technology is shifting toward:

Independence from ground networks

Free satellite-based corrections

Global high-accuracy services

BD-PPP and Galileo HAS represent the future of GNSS—offering reliable, accurate, and cost-effective positioning for professionals worldwide.
