Technology


AST-201 is a miniature high performance GLONASS Baseband Correlator aimed at interfacing with any standard GLONASS RF front-end and a General Purpose Processing element to realize a GLONASS Receiver.

AST-201 is a 16-channel implementation capable of acquiring and tracking up to 16 GLONASS satellites simultaneously. It receives a 2-bit digitized IF from the RF front-end (eg. AST-GLSRF from Accord) and delivers the correlation results over the SPI interface.
