It can track all GPS signals (L1/L2/L2C/L5) as well as GLONASS (L1/L2). It has 8 GB on-board memory, integrated battery providing up to 15 hours operation and has tracking and storage rates of up to 50 Hz. WAAS/EGNOS, MSAS, Galileo (GIOVE-A, GIOVE-B) and L-band (OmniSTAR) Satellite Based Augmentation (SBAS) compatibility. It can also be used as a temporary base station to broadcast RTK corrections. Static GNSS surveying horizontal accuracy is +/-3 mm + 1 ppm RMS (baseline <30km)."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1434" ; skos:note "accepted"@en ; skos:prefLabel "Trimble NetR9 GNSS reference station"@en ; skos:related , . skos:narrower . skos:related .
