• The Infrakit FIELD™ app can be installed on a supported mobile device, accuracy limited to its positioning capability.
  • You can use Bluetooth or Wi-Fi to connect an external positioning device for improved accuracy.

GPS has had about a five-meter accuracy since 2000, when selective availability was lifted.

A typical GNSS receiver (rover or smart antenna), without correction signal, is accurate to within about two meters.

Since 2018, GPS receivers that use the L5 band and Galileo receivers that use the E5a band, can have much higher accuracy to within 30 centimetres. This requires a dual-frequency GNSS smartphone.

Classical differential positioning uses another GNSS receiver fixed as a reference station at an accurately surveyed position. The base station receives GNSS signals, determines range errors, and broadcasts corrections to other rovers via radio.

Virtual reference station (VRS) networks use real-time kinematic (RTK) solutions to provide centimeter-level or better accuracy.
