GUILDFORD, UK (SSTL PR) — Surrey Satellite Technology Ltd (SSTL) has successfully demonstrated GNSS-Reflectometry (GNSS-R) from its 18kg DoT-1 satellite. SSTL has pioneered the new field of GNSS-R with successful payloads on board TechDemoSat-1 and the CYGNSS constellation, and is continuing to develop the technology and data analysis in pursuit of this new science.

The latest GNSS-R payload on-board the DoT-1 satellite is incorporated within the new small form factor Core Avionics module integral to all SSTL’s future satellite platforms. This innovation paves the way for any SSTL satellite that can accommodate a nadir pointing antenna to become part of a GNSS-R small-sat constellation.

NOAA to Purchase Commercial Radio Occultation Weather Data

by Douglas Messier
Managing Editor

NOAA will purchase radio occultation (RO) data from commercial companies after determining that the measurements are useful in improving weather forecasting.

In a report released last week, NOAA said measurements provided by Spire Global and GeoOptics satellites during the second round of the Commercial Weather Data Pilot (CWDP) program in 2018 and 2019 demonstrated the utility of commercial RO data.

SILVER SPRING, Md. (NOAA PR) — With predictions for an above-normal 2020 Atlantic hurricane season, NOAA forecasters have added meteorological muscle from a new  combination of satellite data flowing into its computer models. 

The Constellation Observing System for Meteorology, Ionosphere and Climate (COSMIC-2) is a new fleet of six small satellites launched last June. Since May 26, the constellation has begun feeding more than 4,000 vertical sets of measurements of atmospheric temperature and humidity in the tropics and subtropics daily into our forecast models. Measuring the moisture in and around tropical cyclones is important because it is a key ingredient for their development and intensification.

Trump Administration Proposes Deep Cuts to NOAA Budget

by Douglas Messier
Managing Editor

The Trump Administration is proposing a 13.57 percent reduction in the National Oceanic and Atmospheric Administration’s (NOAA) budget for fiscal year (FY) 2021, according to budget documents.

The $4.63 billion proposal would cut NOAA spending by $727.64 million below the FY 2020 budget. Although key satellite and commercial data purchasing programs would received increases, dozens of other programs would see their funding reduced or eliminated completely.

NOAA’s climate change research programs would be reduced by more than half from $169.5 million to $83.2 million. President Donald Trump has called global warming a hoax invented by the Chinese government to destroy the American economy.

UK Space Agency Backs Spire as ESA Space Mission Provider

Swindon, England (UKSA PR) — The UK Space Agency has awarded more than £4 million to Spire Global to demonstrate cutting-edge space technology including ‘parallel super-computing’.

Today’s announcement by UK Government ministers Lord Henley and Lord Duncan, gives the green light to missions designed to showcase the technology and put UK companies into orbit faster and at a lower cost. The UK is the largest funder of the European Space Agency’s Advanced Research in Telecommunications Satellites (ARTES) programme, which transforms research into successful commercial projects.
