GNSS POSITIONING METHODS COMPARISON

STATIC vs RTK vs PPK vs PPP- Which Method Should You Choose?

One Goal

Accurate & Reliable Positioning

Right Choice

Better Accuracy Better Results

Different Methods

Different Strengths

Work Smarter

Save Time Increase Productivity

01. STATIC GNSS

  • Millimeter to centimeter level accuracy
  • Long observation sessions (30 min to several hours)
  • Post-processing required
  • Ideal for geodetic control, monitoring & high-precision surveys
  • Best for establishing base stations and control points
Typical Uses
Geodetic control, scientific research tectonic studies, deformation monitoring. high-accuracy mapping

02. RTK (REAL-TIME KINEMATIC)

  • Centimeter level accuracy
  • Real-time positioning
  • Requires base station or CORS network
  • Corrections sent in real-time via radio or internet
  • Widely used in construction, staking, machine control and engineering projects
Typical Uses
Construction stake-out, topographic mapping, engineering surveys, GIS mapping, machine control

03. PPK (POST-PROCESSED KINEMATIC)

  • High accuracy after post-processing
  • Data collected in the field and processed later
  • No real-time corrections or base station required
  • Ideal for UAV/drone mapping, mobile mapping, remote areas
  • More flexible - process data when needed
Typical Uses
UAV photogrammetry, drone surveys, remote area mapping, corridor mapping, kinematic data collection

03. PPP (PRECISE POINT POSITIONING)

  • No local base station needed
  • Uses precise satellite orbits and clock products
  • Global coverage - works everywhere
  • Convergence time (minutes to hours)
  • Ideal for remote areas & scientific applications
Typical Uses
Remote area surveys, tectonic studies, climate research, marine surveys, long-duration monitoring

CONVERGENCE / INITIALIZATION

STATIC: Not required

RTK: Instant

PPK: Not required

PPP: 5 min - 2+ hours

REQUIREMENTS

STATIC: Time & stable setup

RTK: Base or Network

PPK: Post-processing software

PPP: Precise products

COMMON APPLICATIONS

  • Construction & Stake-out: RTK
  • UAV / Drone Mapping: PPK
  • Control & Monitoring: STATIC
  • Remote / Scientific Research: PPP
ADVANTAGES
LIMITATIONS
STATIC: Highest accuracy, very reliable for control & research.
STATIC: Time consuming, not suitable for fast work.
RT:: Real-time results, high efficiency, widely used in
RTK: Needs base/network, limited range by radio/Internet.
PPK: No need for base, flexible, works in remote areas.
PPK: No real-time results, needs post-processing.
PPP: Global coverage, no base or network required.
PPP: Longer convergence time, lower accuracy compared to RTK/PPK.

HOW TO CHOOSE THE RIGHT METHOD?

→ Need highest accuracy for control or research?
→ Use STATIC Need real-time results for construction or engineering?
→ Use RTK / Doing drone/UAV or mobile mapping?
→ Use PPK Working in remote areas with no network? → Use PPP

KEY TAKEAWAY

There is no single "best" method. The best method is the one that fits your accuracy needs, project environment, equipment, and workflow.

PRO TIPS

•Always check PDOP & satellite count
• Use dual frequency receivers
• Plan your survey before going to field
• Process & verify your results
