Status and Plans for the BARD Network
The table above provides a list of the BARD stations maintained by the BSL. Five receiver models are operating now: Trimble 4000 SSE (T-SSE), Trimble 4000 SSI (T-SSI), Trimble NETRS, (T-NETRS), Ashtech Z12 and Ashtech Micro Z (A-UZ12). The replacement of the Ashtech Z12 by Trimble NETRS will make the receiver array more homogenous. The telemetry types are listed in column 6. FR = Frame Relay, R = Radio, Mi = Microwave, WEB = DSL line, NSN = US National Seismic Network (VSAT: satellite telemetry). Some sites are transmitting data over several legs with different telemetry. The sites 28 to 30 are in progress. Changes from the last yer's network table are highlighted in bold. For these 3 sites, the instrumentation is available and permit request procedures have been completed.
