摘要

Côte d'Azur天文台(OCA)使用了三种独立的时间传递技术:GPS、TWSTFT和T2L2。2013年秋季，开展了GPS接收机相对校准活动。该活动的结果，主要是为了比较GPS与T2L2，已经允许校准OCA和op之间的TWSTFT链接。我们为OCA计算了CALR = 7111.9 ns，在k = 2时不确定度u = 2.8 ns。从这个校准中，我们用三角形闭合技术描述了其他链接。

Calibration of the TWSTFT link between OCA and OP using a GPS link calibration

Three independent time transfer techniques are in operation in Observatoire de la Côte d'Azur (OCA): GPS, TWSTFT and T2L2. In Autumn 2013, a GPS receiver relative calibration campaign has been carried out. The result of this campaign, primarily intended to compare GPS with T2L2, have allowed the calibration of the TWSTFT link between OCA and OP. We computed for OCA the value of CALR = 7111.9 ns, with an uncertainty u = 2.8 ns at k = 2. From this calibration we caracterise the others links with the triangle closure technique.
