TSUR-B Uplink


The Telonics Satellite Uplink Receiver, Version B (TSUR-B) is designed for reception, decoding, and direct data logging as well as analysis of PTT transmissions. Used in the field since the mid 1980's, the diagnostic receiver has proven a reliable tool for researchers working with Argos satellite telemetry.
TSUR-B features include:

  • Receives all or selected PTT ID codes.
  • Built-in RS232C interface for time/date coded data output.
  • BNC input port allows measurement of PTT RF output power.
  • Designed for field operation (utilizes "AA" batteries.
  • Illumnated Display.
Additional information on the TSUR-B is available in the Telonics Quareterly. (Click here for PDF format, TQVol.9, Number 1, "TSUR-B-The Role in GPS Data Recovery.")
