PD7 - Columbia River Estuary rkm 70

In-river detection system consisting of ten 8ft x 20ft antennas in the Columbia River Estuary. The array (PD7) is located at river km 70 (46.14661N, -123.379867W), is operated by NOAA Fisheries, and was installed for testing on 8 August, 2011 and later modified for continuous monitoring on 11 August, 2011. The array includes an IS1001 transceiver (firmware v1.6.3) and wireless video camera. Electrical power is provided by a solar panel array with backup battery power, and remote communication and video uplink are provided by a cellular modem. Antenna groups are named based on their orientation relative to the pile dike starting with Configuration Sequence 180. Prior to that they were named based on orientation relative to flow.
