The next generation of spaceborne rain radars: science rationales and technology status

The 13.8 GHz Precipitation Radar (PR) aboard the US/Japan Tropical Rainfall Measuring Mission (TRMM) satellite is the first rain profiling radar ever launched into space. A TRMM follow-on mission, called the Global Precipitation Mission (GPM), is currently planned to extend and improve the TRMM acquired rainfall data set.

Utilizing off-the-shelf parts for the next generation of space exploration

Unscreened commercial, off-the-shelf (COTS) parts, in space applications are especially encouraging when the possibility of capitalizing on the extensive development for high-volume consumer applications is considered. Other applications for MMIC parts in space could possibly open new doors in the future.

The Next Generation of Space Telemetry and Telecommand Standards

Standardizing the exchange of data through communications channels that connect spacecraft with their ground systems reduces costs. Efficient coding and packetization promote the automated, error-free transfer of data.
