YSIT-1 GOES Radio Satellite Transmitter

The YSIT-1 is a secure and reliable GOES satellite transmitter built for environmental data.

• Overview

  The YSIT-1 operations are based on version 2.0 of the DCPRS certification standard. The sensor readings are transmitted over the GOES satellite system by linking to any Storm3 or legacy XL Series Data Logger.

  The YSIT-1 is ideal for Surface Water Data Collection Platforms, Meteorological Stations, and Water Quality Measurement Stations.

  • User-selectable operation modes (GOES, METEOSAT, EUMETSAT, and Himawari)
  • Compatible with antennas from 3 to 11 dB gain
  • Minimal GPS updates required (as infrequent as 20 days)
  • Frequency error is less than ± 125 Hz
  • Short-term frequency and stability are better than ±1 Hz
  • RS-232 connectivity
  • USB diagnostics port
  • Transmitted system health
  • Up to 30,000 log entries supported
  • NOAA/NESDIS certified
