102. Global Navigation Satellite System (GNSS) Survey Networks: Geodetic versus Mass Market (I-12-KAMI-039)

Infrastructure Engineering
Written By JT Production Management

Determining a position on Earth at sub-centimetre levels of precision has proven to be feasible with the global navigation satellite systems (GNSS). The formation of surveying networks between an a-priori reference position and a high-end geodetic receiver can deliver ultra-precise positioning solutions for that receiver. However, the implementation of such networks is not very cost effective due to high-end geodetic receivers costing several thousands of dollars.

In recent years, numerous low-cost receivers (that have cost a few hundred dollars each) have entered the mass-market. They incorporate capabilities previously only achieved by high-end geodetic receivers, such as tracking multiple satellite systems and navigation signal frequencies. We have undertaken a comparative research study to evaluate the positioning performance of networks formed by such mass-market receivers.
