[IGSSTATION-8443] SPK100USA: new receiver and antenna

[David Maggert]

Dear Colleagues,

The USGS has replaced the GNSS receiver and GNSS antenna at the Saddle Peak, California (SPK100USA) IGS station. An updated IGS site log has been posted at the IGSCB with the new equipment details. Unfortunately, there is a data outage from 08-APR-2020 until 04-MAY-2022. No data is available during that time period.
