GOES Satellite Transmitters

Figure 34 GOES Satellite Transmitter
The Satellite Radio Transmitter makes telemetry possible through the
GOES, Meteosat, Argos, and SCD satellites.The transmitter has to be
mounted inside the enclosure.The satellite transmitter is provided with
the necessary cables, antenna, coaxial surge arrester for RF-signal, and
all mounting hardware.
The transmitter has Temperature Compensated Crystal Oscillator
(TCXO) which provides the long-term frequency stability necessary to
keep the transmitter on the assigned frequency. Use of a GPS receiver,
either embedded or external offers additional time management
stability. The transmitter is extremely efficient with power and have low
power consumption during a transmission, less than 2.75 A.
GOES HDR300 without the internal GPS provides transmission speed
of 100 or 300 baud. If you later desire having clock synchronization, the
HDR300 easily supports a traditional external GPS or WWV receiver.
The channel and data rate are programmable and can be changed as
often as each transmission. The transmitter can be set to any of the
allowable 199 USA GOES channels (100 and 300 bps) or any 33
International Channels (100 bps).
The GOES HDR1200 transmitter offers the fastest approved baud rate
as well as 100 and 300 bps. It also enables the use of an embedded GPS
in the design, and the HDR1200 transmitter channels and data rates are
programmable on a burst by burst basis. The channel and data rate are
programmable and can be changed as often as each transmission. The
transmitter can be set to any of the allowable 199 USA GOES channels
(100 and 300 bps) or any 33 International Channels (100 bps). For 1200
bps, the transmitter can be set to any of the 1-100 domestic channels.
