Athena announces availability of GPS anti-jam filter

Digital Excision Processing Dramatically Improves GPS Receiver Performance

GAINESVILLE, FL - April 28, 2003 - The Athena Group, a leading provider of high-performance low-power signal processing technology, today announced the availability of the AD-2800, the first member of the Athena Digital Excision Processor Technology (ADEPT™) family. The ADEPT product line enables unprecedented reliability for all GPS receivers by protecting all current and planned civilian and military codes (C/A, P(Y), M, F) against common interference sources. The AD-2800 establishes new power and performance standards for narrowband GPS signal pre-processing. In military mode, the AD-2800 delivers up to 50db of improved signal to noise ratio yet requires less than 60 mW of power to protect the P(Y) signal. In commercial mode, less than 20 mW of power is required to protect the C/A code.

"GPS is extremely sensitive to interference from a variety of sources, and loss of GPS reference is simply unacceptable," said Dr. Jon Mellott, Chief Technology Officer of Athena. "GPS is now a pervasive part of our national information infrastructure. With the increased reliance on GPS comes an increased need for robust service and immunity from the co-channel interference that renders GPS unusable. ADEPT is easily added to any GPS receiver design, making it possible for both commercial and military users to obtain an unprecedented quality of service."

ADEPT solutions are available for a number of applications and environments, with variable precision and sampling rates. Because of the instantaneous adaptation rates and ability to spectrally differentiate, ADEPT processors can identify and eliminate not only multiple noise sources but also time-variant and frequency-variant interference. Athena's proprietary signal processing technology achieves remarkably high throughput with extremely low power consumption, making the ADEPT family of processors ideal for eliminating interference in all spread spectrum communications, including cellular telephony.
