Common-view GPS time transfer using conventional single channel and multichannel GPS receivers

This paper reports the results of time transfers between the New Zealand and Australian national standards laboratories using both conventional GPS time transfer receivers, and multi-channel GPS receivers programmed to emulate the common-view single channel mode of operation. These two types of receivers have been in operation for around 18 months. The results show that the low cost multi-channel GPS receivers are capable of transferring time with an uncertainty comparable to the old single channel time transfer receivers.
