3rd, 2018 as part of the SpaceX SSO-A: SmallSat Express Mission ultimately achieving a sun-synchronous 575 km orbit. The Compact Spectral Irradiance Monitor (CSIM) 6U CubeSat successfully launched on Dec. It achieved all mission objectives and provided a pathway for future cost-effective cloud observations from CubeSat constellation.Īccurate, long-term solar spectral irradiance (SSI) measurements are vital for interpreting how solar variability impacts Earth’s climate and for validating climate model sensitivities to spectrally varying solar forcing. It was successfully released from International Space Station (ISS) in May 2017, acquired 15-month science data and produced the first global map of the 883-GHz cloud ice.
Funded by NASA’s In-Space Validation of Earth Science Technologies (InVEST) program and Science Mission Directorate (SMD), IceCube is the first CubeSat developed and flown by Goddard Space Flight Center (GSFC) in 2.5 years, using commercial off-the-shelf (COTS) components and subsystems. Emerging CubeSat opportunities allow a fast-track development and spaceflight demonstration of IceCube on a 3-U CubeSat. The IceCube 883-GHz cloud radiometer is the latest of NASA’s efforts to advance the technology readiness level (TRL) of submm-wave receiver technology for future compact, low-cost implementation of Earth observing systems. Submillimeter (submm) wave remote sensing at 200-1000 GHz is able to provide the sensitivity not covered by visible (VIS)/infrared (IR) and low-frequency microwave (MW) sensors (10-183 GHz), and measure cloud ice in the middle-to-upper troposphere. The display is not mobile friendly at the moment, but it does seem to work OK on the IPad.īe sure to let me know how it works, leave us a comment and don’t forget to include your town/country or callsign.Cloud ice play important roles in Earth’s climate and weather systems through their interactions with atmospheric radiation, dynamics, energy and precipitation processes. Have a listen with my SDR, I understand Safari, Firefox and Google browsers work best. I’ve been updating the station text, its work in progress but I’ve added quite a few of the mediumwave station names.
TUNABLE VLF RECEIVER PURCHASE SOFTWARE
The SDR software has a built-in WSPR decoded that works really well, and with time they hope to add further features. I use the Wellbrook loop mounted outdoors at around 5m, but you may be interested in a much less expensive project version as detailed by George M1GEO. The advantage of the active antenna is it works well over the entire HF spectrum, it’s especially good below 5 MHz. The idea of having your own web-based SDR always online, and accessible from anywhere in the world was very appealing and coupled with an active antenna the performance if very good.
You can listen to this SDR online.Īfter using it for a few weeks via the web browser I was sold, it was ideal for HF monitoring, and with remote access with up to 4 independently tunable receivers. Dave has recently moved his SDR to a remote site in the Secret Nuclear Bunker Kelvedon Hatch. The first time I used one was when Dave G7UVW added his to the SDR.hu website.
In April 2016 the KiwiSDR project was born on Kickstarter, the plan was to produce a software-defined radio (SDR) covering shortwave, the longwave & AM broadcast bands, various utility stations, and amateur radio transmissions, worldwide, in the spectrum from 10 kHz to 30 MHz.įast forward and the project has now been completed with the first units having been dispatched If you find the SDR useful consider making a small donation to help with its upkeep.
The SDR is online 24×7 for your enjoyment.
