Spectrum's Solutions at Satellite 2009
]
Spectrum will be exhibiting its range of satellite communications solutions at the Satellite 2009 Conference.
Visit Spectrum in Booth 161 and see
the SDR-4803 SATCOM Embedded Radio Module Demonstrator
in action. The demonstration
features two rugged, conduction-cooled SDR-4803 modules each containing an embedded single-channel RF stage and
Field Programmable Gate Array (FPGA) System-on-Chip (SoC) processor to transmit and receive a video and audio data stream at up to T1 speeds (1.5 Mbps) using an
OFDM-based waveform.

Application Note: High Sensitivity, High Capacity Gateway for Asset Tracking and Remote Monitoring
]
|
Spectrum developed the
Simplex Remote Telemetry Gateway Receiver
for a customer's asset tracking system on a constellation of low Earth orbit (LEO) satellites.
Spectrum's solution showed a significant improvement in beacon detection and channel capacity over
the existing legacy system:
» 8 x improvement in receiver sensitivity (>9 dB)
» 10 x increase in channel capacity (20 simultaneous signals per beam)
» Time tagging of message to 1 microsecond accuracy
» Frequency at time tag to better than 1 Hz accuracy
» A single system for both commercial and defense applications
|

|
With increased sensitivity, the Gateway Receiver can now detect beacons as low as 10 degrees off the horizon.

Satellite Communications and Software Defined Radio - Have A Say
]
The SDR Forum has created a Satellite Communications Special Interest Group (SATCOM-SIG).
The role of the SATCOM-SIG is to provide a venue for SDR Forum members involved in satellite communications to collaborate in promoting
development of advanced SATCOM systems and identify emerging markets for Forum member organizations. As a key part of this effort, the SATCOM-SIG
will evaluate the unique requirements associated with commercial and defense satellite communications, and identify opportunities to develop systems and
architectures for the next generation of SATCOM user.
Spectrum is a contributing member for the SATCOM-SIG. If you are a user, equipment supplier, designer, or service provider of commercial or defense
satellite communications, and believe that satellite communications is not an alternative to, but an integral element of, the emerging global
communications fabric - your participation in the SATCOM-SIG is highly recommended.
To get involved in the SATCOM-SIG, contact the SDR Forum CEO Lee Pucker at
lee.pucker@sdrforum.org or Group Chair Bob Schutz at
bob.schutz@viasat.com.
The SDR Forum is a non-profit international industry association dedicated to promoting the success of next generation radio technologies.

Have a Multi-Channel, Multi-Band Modem Requirement? Let Spectrum's SDR-4002 TMCM Do the Heavy Work
]
The SDR-4002 Tactical Multi-Channel Modem (TMCM) is a
rugged, conduction-cooled IF-to-Ethernet modem processing subsystem. The SDR-4002 TMCM architecture is
cost-optimized for systems requiring multi-band and multi-channel RF/IF operation. It is an ideal platform for radio manufacturers and system
integrators to meet the primary analog and modem processing needs of a variety of applications including radio gateways, tactical radio, and
terminals. The SDR-4002 TMCM features a software reconfigurable processing engine, as well as multiple PHY/MAC layer and analog IF processing cards.
The subsystem is designed to run a variety of legacy narrowband waveforms, as well as current generation ad-hoc networking and IP-centric waveforms.
The default SDR-4002 TMCM configuration supports four IF inputs and four IF outputs, with each supporting industry standard analog IF frequencies such as 21.4 MHz and 70 Mhz.
The modem can be easily scaled up to eight channels and is ideal for multi-band tactical radio or gateway applications.
