RTK is important as traditional GNSS receivers, estimate their location using the differential in times transmitted from multiple satellites.

As a result, the accuracy GNSS systems is only guaranteed to between 1 – 4 metres.

This means traditional GNSS/GPS systems simply cannot provide the accuracy needed for many safety applications and could even increase risk if deployed in some scenarios.

To combat this inherent inaccuracy in GNSS, OWL uses RTK to provide centimetre-level accuracy.
