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 ...
Almost ready. The beam-hopping 5G satellite satellite - JoeySat - that will provide high-speed internet connectivity from LEO has left the OneWeb Florida facilities, heading for a launch pad in California...
Texas Instruments has introduced a pair of closely-related dual-output PWM dc-dc converter controllers for space applications, one radiation-hardened and the other radiation tolerant. Both can operate across 100kHz to 2MHz and with external synchronisation, and will work with silicon or GaN power transistors via suitable drivers. Both include a 0.613V +0.7%/-1% reference. TPS7H5005-SEP is the radiation-tolerant part SEL, SEB, and ...
Astronode S is an RF module from satellite operator Astrocast, intended to be built into land or sea-based battery-powered IoT devices. It is based on an architecture developed by French research lab CEA-Leti, and an IC co-developed with Astrocast to optimise its link budget and power consumption to suit a particular Astrocast’s ground-to-satellite protocol – which offers a variable user ...
EPC Space has announced 100V and 200V rad-hard GaN power transistors for space use “with ultra-low on-resistance and extremely low gate charge for high power density solutions”, according to the company. Judge for yourself, these are the typical values: EPC7007B (200V 18A): 28mΩ 5.4nC EPC7018G (100V 90A): 6mΩ 11.7nC “These additions to our rad-hard product line enable a generation of ...
Anritsu has created the MS27201A remote spectrum monitor series, that includes a 43.5GHz version for new satellite downlink bands. A 110MHz measurement bandwidth supports common satellite downlink spans, DANL (displayed average noise level) is -164dBm and the typical TOI (third-order intercept point) is +20dBm. Other MS27201A versions work up to 9GHz or 20GHz. All work down to 9kHz. “Combining RF performance ...
