Emcore Solar Panels Power LDCM Satellite

The orbital-built satellite will use the firm's BTJ triple-junction III-V solar cells delivering 3,750W of power at the end of life
Emcore solar panels are powering the Landsat Data Continuity Mission (LDCM) satellite that was successfully launched on February 11th, 2013 from Vandenberg Air Force Base in California.

LDCM was designed, built and tested by Orbital Sciences Corporation for NASA to support the Landsat Earth observation program that began over four decades ago. The LDCM satellite continues a 40-year legacy of seven previous satellites that have collected vital data and images of the Earth's surface and environment.

NASA and the U.S. Geological Survey (USGS) share responsibility for the LDCM program. NASA's Goddard Space Flight Centre oversaw development of the flight systems including the LDCM spacecraft and the onboard instruments, and is responsible for mission operations, launch, and in-orbit checkout. 

The USGS will operate the satellite and the Landsat ground network, image-processing and archive facilities. The data collected constitutes the longest ongoing record of the Earth's surface as seen from space and benefits many industries including agriculture, geology, forestry, regional planning, education, mapping, emergency response and disaster relief.

The knowledge gained contributes to research on climate, carbon cycle, water cycle, ecosystems, biogeochemistry and changes to Earth's surface, as well as our understanding of visible human effects on land surfaces.  

LDCM joins Landsat 7, which is currently in orbit. Once the spacecraft completes in-orbit testing and is operated by the USGS, it will be renamed Landsat 8, reflecting its place in a distinguished legacy of highly-productive spacecraft.

The satellite has two new spectral bands that will allow it to detect clouds on coastal zones. In addition, it will produce more than twice as many images per day than the Landsat 7. LDCM is approximately 20 feet tall with a 9-foot diameter at its widest point.

The solar array has four Emcore solar panels that will extend 32 feet from the satellite when deployed and feature high-efficiency BTJ triple-junction solar cells delivering 3,750 watts of power at End-Of-Life (EOL).

"Emcore is proud to have once again partnered with Orbital on the deployment of critical on-orbit capability," says Brad Clevenger, General Manager of Emcore's Photovoltaics Division. "We appreciate the opportunity to contribute to this important mission for NASA and the U.S. Geological Survey and we look forward to seeing LDCM's many contributions to earth science."





AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
