SRI is a leading supplier of advanced products for defense, civil, and commercial satellite, aircraft and missile test range, and test & measurement data communications and telemetry applications. SRI has been able to leverage knowledge and experience in these markets to apply proven, reliable military SOQPSK-TG telemetry transmission techniques to commercial Land Mobile Radio (LMR) data communications. Previous industry practices relied on variations of FSK and GMSK techniques to meet narrowbanding 6.25 KHz channel requirements. This breakthrough significantly improves link reliability and performance for applications requiring extended operating ranges over difficult terrain. The radio features an output power level up to 45 Watts and is available for domestic and most international uses supporting analog and digital signals.
“Summation Research is honored to continue our support of GE Transportation”, said Tom Drago, Vice President of Business Operations at Summation Research. “A unique ability to apply our knowledge and experience gained in high bandwidth satellite, aircraft, and range telemetry markets to this challenging narrowband railroad telemetry requirement allows SRI to continue a long standing successful business relationship with GE. This breakthrough can also provide new methods for small satellite telemetry and communications needs.” The products to be supplied under this contract are part of a family of transmit and receive Land Mobile Radio, Satellite and Range Telemetry and Communications, and Wireless Sensor Telemetry equipment built by SRI.
