sat-nms Radiometer Controller and Detector
Radiomters are used for the following applications:
- IOT (In-Orbit-Test) measurements of satellite communication payloads
- Long-term recording of propagation conditions
- Atmospheric attenuation measurement
- Water Vapor Content Measurement
- Uplink Power Control
The radiometer type implemented is a noise balancing / noise injection type of radiometer and includes all other additional functions necessary for a radiometer. These are for example the antenna control functionality for azimuth and elevation control of the radiometer antenna. By this means also an automatic tip curve calibration is possible. Also automatic calibration with a cold load is controlled via the radiometer controller. And the complete high precision tempertaure control of the feed box inclduing the microwave and IF receiving system is performed via the software of the radiomter controller.
Customers can upgrade their existing radiometers with this controller in an easy way. This is fully independent for which receive frequency (fort example 13,5GHz, 22GHz or 60GHz) the radiometer is build, as this controller interfaces on IF and control level to the radiometer frontend. So the existing waveguide sections can be kept as they are.
The two new modules of the sat-nms Product Family form the core of a radiometer. These are the sat-nms RMC Radiometer Controller and sat-nms RMD Radiometer Detector Modules. The modules are developed and manufactured by SatService GmbH.

Key Features
- Noise Balancing/ Adding Radiometer Type
- High Gain stability
- Receive Frequency independent
- Univerdsal Design
- Wide IF frequency inputrange
- Compact, small DIN rail compatible box
- TCP/IP based design
- HTTP Web Browser interface
- Integrated FTP Server
- Full remote administration and support capability
One additional key feature of this radiometer controller, like in any equipment belonging to the sat-nms family, is its full web- and ftp-server capabilities. It provides a Ethernet TCP/IP interface and includes a compact flash of 2GB for data logging purposes.
All measurement results and the monitoirng parameter are available via HTTP Web Interface via internal Web Server and can be monitord and controlled from a remote IOT software either via http get functions or via RS232 interface.
