New Zealand launch of two TROPICS radiometers

Another two TROPICS radiometers were launched on the  26th May - details are here  - and the Youtube video here

and are - to quote - the PI, Bill Blackwell ....."all four are working great!"

 At  2 am  BST, Monday 8th May 2023,  the New Zealand launch of two TROPICS radiometers puts TK
designed, made and tested antennas into orbit to observe hurricanes.

....the 100mm cube tri-band antennas use a polarizing grid to combine co-aligned beams covering
atmospheric rotation lines of water and oxygen: The MIT/ Lincoln Labs designed radiometers will provide
the timely imaging of hurricanes, from their 30 degree inclined equatorial orbit.

More details of TK's antenna are here , coving these mm-wave bands:


Freq Band                               Beamwidth [deg]
88.15-94.15 GHz                     ≤3.0 at 92 GHz
114.5 to 118.75 GHz               ≤2.4 at 118 GHz
183.3 to 205 GHz                    ≤1.5 at 183 GHz
