Subject: [SIR-Mail] No.973: NAUS: antenna change From: Sonia Costa Author: Sonia Costa, IBGE Station NAUS(Manaus),have new antena since day 144 (24/05/2014) Please don´t use data from 126(06/05/2014) to 143(23/05/2014) when antenna was tracking only L1 I would like to report a problem that we had in some RBMC stations regarding Trimble antennas. The antenna model TRM59800.00(choke ring GNSS) stopped to track L2 and this was the case of : POAL(recently changed), NAUS(recently changed), PAIT, PRMA, PEPE, BAIR and BAIL(recently changed) So, soon, data from stations PRMA, PEPE and BAIR will not be available until we solve this problem.
