Setting Up Your First Static GNSS Survey Using Free Tools
Static GNSS surveying is the gold standard for collecting highly accurate geodetic coordinates. It’s widely used for boundary surveys, engineering control points, and base station setup. The good news? You donโt need expensive software to get started โ just a good GNSS receiver and a few free tools.
This tutorial walks you through how to perform a static survey using RTKLIB or Emlid Studio โ both completely free and trusted by professionals.
๐ฆ What You Need
- โ๏ธ A GNSS receiver capable of raw data logging (e.g., Trimble R8, Emlid Reach RS2, Leica GS series)
- โ๏ธ Power supply and tripod for stability
- โ๏ธ Mobile app or interface to start logging (Emlid app, data collector, etc.)
- โ๏ธ Free processing software: RTKLIB or Emlid Studio
๐ง Step-by-Step Guide to Static Survey
Step 1: Setup GNSS Receiver on Stable Point
- Mount your receiver over a known or unknown point using a tripod and tribrach
- Measure antenna height accurately (vertical from point to ARP)
Step 2: Start Logging Raw Data
- Begin recording in RINEX or raw format (UBX for u-blox receivers)
- Set logging duration: 30 minutes minimum for short baselines; longer for higher accuracy
Step 3: Download and Prepare Files
- Transfer raw logs (RINEX, .UBX) to your PC
- Rename clearly (e.g., SITE1_2025-07-26.obs)
Step 4: Process in Emlid Studio or RTKLIB
- Use the Static Processing mode
- Input base station RINEX and navigation file
- Set antenna model and height
- Run the solution to calculate a precise coordinate (usually WGS84 or local datum)
Step 5: Export the Results
- Export CSV or LLH (Latitude, Longitude, Height)
- Use for control points, CAD imports, or RTK base initialization

๐งฎ How Long Should You Log?
Baseline Length | Recommended Logging Time |
---|---|
< 10 km | 30โ45 minutes |
10โ50 km | 1โ2 hours |
> 50 km | 4+ hours or overnight |
๐ฏ Use Cases for Static Surveying
- โ๏ธ Establishing GNSS control points
- โ๏ธ Geodetic and cadastral survey projects
- โ๏ธ Base station setup for long-term RTK/PPK
