Transponder

Product description

Transponder products include five kinds of products, the main function of which is to achieve Ground TT&C or TT&C for TT&C satellite.The working frequency band of these products covers S/Ka frequency band.There are two TT&C methods, which are simulation system and spread spectrum system. These products can be selected according to different needs, suitable for LEO, MEO, GEO satellites or spacecrafts.
