Evaluation of Low-Cost, Centimeter-Level Accuracy OEM GNSS (Global Navigation Satellite Systems) Receivers

Centimeter-level accuracy in Global Navigation Satellite Systems (GNSS) is achieved using a complex algorithm known as Real Time Kinematic (RTK) processing. RTK-capable receivers require precisely calibrated antennas to receive the signals transmitted by the GNSS satellites. In addition, they must receive and process corrections from a ground network of GNSS receivers. This makes RTK-capable receivers costly (in excess of $10,000) and bulky, making them unsuitable for cost and size-sensitive automotive applications. GNSS equipment manufacturers have started advertising inexpensive (less than $1,000) and compact RTK-capable receivers, but data supporting this claim is not publicly available. This project aims to provide an independent performance assessment in realistic settings encountered in transportation applications.A number of low-cost, commercially available, off-the-shelf GNSS receivers will be evaluated against high-end, survey-grade GNSS receivers.
