Common-View Time Transfer Using the Two-Channel Fast-Sequencing GPS Receiver K+K GPS6-2K

Abstract

Two 2-channel fast-sequencing GPS receivers (Type K+K GPS6-2K made by K+K Messtechnik GmbH, Braunschweig, Germany) have been studied in co-location and in comparison with the NBS-type receivers used at the PTB for the regular GPS CV-time transfer. The new receivers consist of two channels (the "Tracking Channel" and the "Data Channel"), a built-in time interval meter, and PC software. The "Tracking Channel" either continuously tracks a single satellite or sequentially tracks all satellites in view. Both the code phase and the carrier (delta) phase are measured and combined to yield a smoothed reading of the received satellite time.
