Distributor Rutronik has added three surface-mount RTK-enhanced GNSS modules from Unicore to its portfolio. RTK – ‘real time kinematics’ – is a service that increases the accuracy of satellite navigation systems.

At the Small Satellite Conference in Utah, Imec announced a hyperspectral sensor with an on-chip line-based filter covering 450 – 900nm in 96 bands. It had equidistantly divided spectral bands and, compared with its previous generation, double the TDI (time-delayed-integration) capacity – to 10 line per band. Underneath the filter is a ‘2/3inch’ 2,048pixel image sensor from AMS – the ...
Q-Tech has added high-stability microprocessor compensated crystal oscillators (MCXOs) and oven-controlled crystal oscillators (OCXO) to its product range for low-earth-orbit satellite timing and frequency generation. All are available with either sinewave or CMOS logic outputs. QT2021 is the MCXO series, available in standard frequencies from 10 to 100MHz, Key features are radiation tolerance to 50kRad(Si) TID, frequency stability over temperature ...
EPC is aiming at satellites with an application note on four-phase dc-dc point-of load converters using multiple 26 x 19mm modules. The note, AN005, picks a radiation-specified current-mode PWM controller from Texas Instruments (TPS7H5001-SP) as a source of PWM waveforms. Each TPS7H5001-SP can produce two pairs of upper and lower PWMs for a total of two phases, and TPS7H5001-SP has ...
Microchip Technology has announced a family of radiation-tolerant isolated dc-dc 50W power converters, in nine variants with single and triple-outputs ranging from 3.3V to 28V. LE50-28 power converters are designed to meet MIL-STD-461. The power converters have a companion EMI filter. This series provides flexibility to parallel up to four power converters to reach 200W. “The family of devices enable ...
Vites has chosen a beamforming IC from Oxford-based Ensilica for a vehicle satellite communication terminal. The terminal, called Visat-Ka, is intended to provide high-speed connectivity from moving vehicles anywhere on the Earth using low earth orbit (LEO) and other non-geosynchronous (NGSO) satellites. As such, it has to steer its Ka-band phased-array antenna to maintain link gain. As well as satcom-on-the-move ...
Microchip is aiming at satellite designers with a development kit built around its radiation tolerant RT PolarFire FPGAs, for which MIL-STD-883 Class B qualification has been gained and both Class Q and Class V qualification have been sought. October 2023 update: RT PolarFire FPGA’s are now QML (qualified manufacturers list) Class Q qualified, as designated by the US Defense Logistics ...
The U.S. National Geospatial-Intelligence Agency (NGA), its National Reconnaissance Office (NRO) and U.S. Space Command – have signed an agreement to better enable the protection of commercial space assets. Described as a first-of-its-kind agreement, they plan to “outline a framework” to help preserve commercial remote sensing space assets considered vital to the United States’ intelligence collection mission. The three agencies ...
ESA has begun the controlled destruction of its Aeolus global wind-measuring satellite. Launched in 2018, the 1.3 tonne satellite has already worked 18 months longer than its planned three year mission, but is now running out of orbit-maintaining fuel. Matter and radiation released by recent solar flares and coronal mass ejections have temporarily increased drag in space, and ESA is ...
Smiths Interconnect has created an EMI flange for its high-speed NXS connectors, intended for use in satellites. It interfaces between the PCB mounted receptacle and the enclosure panel or bulkhead to minimises the risk of electrical interference flowing from external sources into the enclosure, and vise versa. The EMI receptacle has a gold plated aluminium body that is assembled into ...
