How accurate is GNSS?

4 March 2021
Category: GNSS Systems

GNSS accuracy is dependent on the type of receiver and technology involved. For example, whilst a GPS Smartphone can offer an accuracy of around 4-5m in open skies, an advanced commercial GNSS system such as Trimble’s R12i can offer an accuracy of up to 3mm. GNSS accuracy can be affected by external conditions such as high buildings, heavy tree canopy or an insufficient number of satellites. The R12i features technology that makes it the most reliable choice for operating in inhospitable GNSS conditions.
