From H.vanderMarel at tudelft.nl Mon Apr 20 03:25:21 2020 From: H.vanderMarel at tudelft.nl (Hans van der Marel - CITG) Date: Mon, 20 Apr 2020 10:25:21 +0000 Subject: [IGSSTATION-7935] KOS1: Lost data, receiver replacement Message-ID: <1bc467f8a6f64ceda690e931d0038730@tudelft.nl> Dear all, The PolaRx4 receiver at KOS1 developed a problem on 15 April 2020 around 17:30 UTC (possibly due to lightning strike) resulting in fewer and fewer satellites being tracked, eventually stop tracking in the morning of 16 April 2020 at around 07:30 UTC. The receiver was replaced by an identical PolaRx4 with s/n 3002074 today 20 April 2020 and resumed tracking around 07:30 UTC. We plan to upgrade the receiver to a PolaRx5e later this month. An updated logfile has been submitted to the EPN and IGS. Hans van der Marel
