What is the accuracy difference between Fixed and Float RTK?

Fixed RTK typically delivers ±8 mm horizontal and ±15 mm vertical accuracy. Float RTK carries ±300–1000 mm of positioning error depending on baseline length and atmospheric conditions.

Why does my RTK show Fixed but coordinates are still wrong?

Common causes are a datum mismatch (wrong coordinate system), an incorrect geoid model applied to elevation, or an antenna height entry error.

How do I know if multipath is affecting my survey?

Multipath typically shows as unstable repeated measurements — the same physical point measured three times gives results differing by 20–50 mm rather than the expected ±8 mm.

Can I survey during ionospheric storms?

RTK accuracy degrades during geomagnetic storms (Kp index above 5). For precision engineering or cadastral surveys, postpone sessions until the Kp index drops below 3.

What is the maximum reliable CORS baseline for centimetre accuracy?

Most CORS networks guarantee ±10–20 mm horizontal accuracy within 50 km of the nearest reference station. Beyond 70 km, deploy a self‑deployed base station within 15 km of the survey area.

APEKS AP30 Laser (M12L) Wins in Laser GNSS Category at ГНСС Баттл 2025 в Казани

July 2025

We are proud to announce that the APEKS AP30 Laser (M12L) has taken first place in the laser GNSS receiver category at the prestigious ГНСС Баттл 2025 в Казани, held on May 17–18, 2025, in Kazan, Russia.

Competing against over 30 renowned GNSS brands, the AP30 Laser (M12L) demonstrated outstanding laser-based positioning precision, fast signal acquisition, and stable field performance. Its success highlights the AP30 Laser (M12L) as the best laser GNSS receiver in Russia for 2025.

APEKS GNSS solutions are widely recognized across geodetic, construction, and cartographic sectors. In addition, the AP30 Laser (M12L) is increasingly trusted in Russia’s engineering surveying industry (инженерные изыскания), which is regarded as a specialized and essential field requiring high precision and field reliability.

The success at ГНСС Баттл 2025 reflects APEKS’s dedication to innovation and its growing role in supporting infrastructure and land development projects across Russia and beyond.

APEKS — Precision. Performance. Possibility.
