6.7.4. TELONICS TGT-1 GOES TRANSMITTER
Coastal Environmental Systems uses the Telonics TGT-1 GOES transmitter, normally, with the TTL
standard interface. This unit has the following specifications:
Size: 4.4” 6.4” 3.5”
Weight: 2.2 lb.
Frequency: 401.701 - 401.998 MHz (402.0025 - 402.0985 MHz international)
Temperature: -40°C to +50°C operational, -60°C to +80°C storage
Humidity: 90% non-condensing
Current: 3A maximum, 2.2A typical during transmission (50 load); < 10 mA quiescent
Voltage : 10.5 VDC to 14.0 VDC
To meet the required timing accuracy, the TGT-1 provides timing to a real-time clock that manages the
transmit window scheduling. Once deployed, TGT-1’s clock is capable of running within GOES
specifications for 420 days without adjustment. NOAA has certified that the Telonics regional and
international transmitters meet all required standards.
