1. Status of USGS Surface-Water Programs and Networks: An OSW Prospective Robert Mason Data Chiefs’ Meeting December 4, 2013 The Role of the GOES DCS in the USGS Streamgage Network –a Users Prospective Robert Mason U.S. Geological Survey March 27, 2015

2. USGS Mission Provide reliable scientific information to describe and understand the Earth; minimize loss of life and property from natural disasters; manage water, biological, energy, and mineral resources; and enhance and protect our quality of life. 135 years old 8,500 Full-time employees $1.02 B budget What do we do? Research Assessments Monitoring

9. GOES and HRIT Data Transmission

10. GOES – Current Usage and Cost USGS GOES sites >10,000 (USGS is by far the largest user of the GOES DCS system.) 57 GOES Channels Total average cost is ~$129/year (actual cost per state) $200k for EDDN. Investment in GOES Millions invested so far in hardware and software ( $32 million in deployed GOES dcps and antennas alone). (Basic dcp + antenna ≈ $2,500-$3,500/each). Support staff salaries

11. Strengths & Weaknesses - GOES Weaknesses Limited in size and frequency of data transmissions Unusable for media transmission 1-way Limited upgradability Lack of alternate or supplemental telemetry. Strengths Reliable Low Operational Cost Established Infrastructure Adequate for most existing sites currently operating Government owned Geostationary Satellite Message traffic processing already in place

12. GOES and HRIT Data Transmission NOP Series 1694.3- 1694.7 MHz; RSTU Series 1679.7- 1680.1 MHz; LRIT N 1691.0 MHz HRIT R 1694.1 MHz

13. Our Questions? Given that GOES is weak, what does “sharing” mean for our signals? Will exclusion zones be permitted? Can we create “guard bands” around GOES frequencies? Can we increase the power of GOES signals?

14. Questions??
