4-Channel Rack-Mount SATSIM

2-Channel Bench-Top SATSIM

1-Channel Bench-Top SATSIM


For more than two decades, SmartSAT's UHF satellite simulators have set the standard in test and measurement for government and prime contractor labs worldwide. Selected by DISA as the "gold SATSIM" for UHF SATCOM testing and embedded in the Joint Interoperability Test Command (JITC) certification facility, SmartSAT's SATSIMs are used to evaluate and certify all UHF SATCOM radios prior to deployment and transmission over U.S. satellites.
Easy to use and incredibly reliable, SmartSAT's family of SATSIMS are designed for years of 24/7 operation. Available in one-channel,  two-channel, four-channel and briefcase models. 

•  accurately simulates satellite characteristics
•  selectable external or internal reference
•  fully controllable signal and noise levels
•  fully programmable propagation time delay 
•  internal white noise generator
•  enhanced remote PC operation
•  intuitive touch-screen display
•  Legacy DAMA DC Mode CCOW and other options available


1-Channel Briefcase SATSIM


Just like its big brother, SmartSAT's Briefcase SATSIM features all the capability of a personal satellite channel but with the added benefit of complete portability. Equipped with a three-hour battery, removable touch-screen display, and onboard accessories, SmartSAT's Briefcase SATSIM is ideal for on-the-move SATCOM testing, including flight lines, shore-to-ship platforms and mobile SATCOM sites.

•  three-hour battery operation
•  external calibration
•  ruggedized case


Combiner Attenuator Test Set (CATS)


CATS  is a consolidated RF signal combiner/splitter attenuator system that brings order and efficiency to the RF test environment. Designed to simulate conditions found in UHF SATCOM over-the-air RF transmission and reception, the CATS is ideal for testing environments that require networked radios and for training with multiple, simultaneous users.

•  accepts up to six, simultaneous, 100 watt UHF uplink transmitter inputs 
•  provides programmable signal level control by channel
•  combines downlink signals into a single RF environment
•  allows for the insertion of noise from an internal broadband noise generator
•  allows up to eight receivers to connect simultaneously via an eight-way downlink splitter
