[IGSSTATION-5583] ESCU back on-line with new antenna

Author: Mike Craymer

Site ID:   ESCU
DOMES No:  40168M001
Location:  Escuminac, New Brunswick, Canada

Further to IGSSTATION-5558, ESCU is back on-line as of today. A broken antenna cable connector necessitated replacing both the antenna cable and the original Ashtech choke ring antenna. The antenna was replaced with a Trimble choke ring TRM29659.00. Due to the faulty antenna cable, data posted to the IGS archives from Day 262 (2013-09-19) until Day 269 (2013-09-26) should be considered suspect. An updated site log has been submitted to the IGS.
