UK wins 70cm radar satellite contract

BBC News reports that the UK has won the contract for the Biomass P-Band
432-438 MHz *Synthetic Aperture Radar* (SAR) satellite

In 2002 the FCC's WRC-03 Advisory Committee and the National
Telecommunications and Information Administration's (NTIA)
Radiocommunications Conference Subcommittee determined that SAR
transmissions could periodically impact amateur reception and even held*"the
potential for significant interference."*

At the World Radiocommunication Conference 2003 (WRC-03) 432-438 MHz was
allocated to the Earth Exploration Satellite Service (Active), although
with a lower power level than had first been proposed.

To date there has been no operation of SAR in this band but it is now about
to be used for the first time. On April 28, 2016 Russia launched the first
432-438 MHz band SAR satellite AIST-2D

The Biomass 70cm SAR satellite is expected to launch in 2021, read the BBC
