  • Abstract:
    USGS GPS receiver ‘use case’. Item 1 - High Precision User (federal agency with Stafford Act hazard alert responsibilities for earthquakes, volcanoes and landslides nationwide). Item 2 - Description of Associated GPS Application(s): The USGS Earthquake Program currently operates 108+ real-time GNSS stations to monitor the San Andreas and other faults Southern California. Real-time GNSS station position data at centimeter level accuracy are streamed into the earthquake early warning system, called Shake Alert (USGS OFR # 2014-1097) that issues alert messages for public safety in case of a major earthquake. The GNSS component of the Shake Alert system augments the inertial sensors and is especially important for the largest earthquakes. The sensitive inertial sensors may go off scale, whereas GNSS data is expected to provide reliable ground motion recordings of displacement even in the largest events. Real-time, uninterrupted GNSS signals are required, without interference, at all times because even a temporary black-out of data from one site could thwart our early warning system (if that station is close to the epicenter of a major earthquake). That is, the RFI could increase our “blind zone” and delay delivering or degrade the accuracy of our Shake Alert message to the public.
