A GPS CV link experience between ROA and IREE

Increasing the number of tracks per day of a TTR-6 receiver has been demonstrated to provide a good tool to reduce the uncertainty of the comparison of two clocks located at laboratories within few hundreds of kilometres after J.Palacio et al. [1]. To check the validity of the results obtained with this cheap and easy-to-implement method, it was necessary to use it in a regular way to link two long-distance separated Timing Laboratories that contribute to TAI. Thus Real Observatorio de la Armada (ROA) and the Institute of Radio Engineering and Electronics (IREE - TP), with a 2200 km baseline, have agreed to set up a computer that controls the spare TTR-6 AOA GPS receiver of IREE in order to increase the daily number of tracks.
