Abstract/Summary

The GCAT Raw Data Logger was developed as part of the Sonic Buoy development program; it was required as an on-board partial back-up system to the (previously untried) VHF Radio Telemetry System for obtaining raw sonic anemometer data. It monitors the sonic anemometer transmit and receive lines to determine the start and end of the sections of data used by the Sonic Processor and logs a single record to a 4 Mbyte Flash EEPROM PCMCIA card at intervals of 48 hours. This document describes in detail the design and operation of the GCAT Raw Data Logger; it is intended to serve the combined purposes of documenting and design and acting as a guide to operating the system and recovering the data.
