VHR-400 Remote Sensing High Rate Modem

The VHR-400 is a fourth-generation high-rate modem specifically designed for remote sensing and earth observation. It combines all our expertise gathered in 30 years of remote sensing and earth observation ground station design, manufacture, and installation.

• Full coverage of the commercial remote sensing band
• Data rates up to 400 Mbps QPSK
• Modular design for tailoring to vari­ous combinations of demodulators, FEC decoders
• Test modulator for end-to-end bit error rate testing without exter­nal test equipment
• Meets the demanding requirements of current and future remote sensing and earth observation missions

Series 924 Multifunction Digital Receive System (MFDRS)

Replaced by VHR-400

For several decades the ViaSat Series 924 Multifunction Digital Receive System (pictured below) has been the choice for the great majority of remote sensing stations in the world. The next-generation digital VHR-400 Remote Sensing Modem has taken its place.
