Product Details

1.Product Introduction

The product is a multi-mode, high performance transponder for satellite TT&C applications. The transponder operates directly at S-Band, with ranging, convolutional encoding, direct modulation, determination of orbit based on VLBI, BPSK and subcarrier modulation all offered as standard features. A RS422 interface for commands and telemetry is also available within the same mechanical envelope.
