The planet Earth keeps time. We all synchronize our clocks to the Earth's rotation. As much as we adjust our calendars with daylight saving or throw in the occasional leap year, it's actually a little more complicated than just that. The normal day clocks in with about 86,400 seconds. However, since 2020, many days have fallen short of that mark. Even though you haven't felt it, geophysicists have measured the Earth's pulse and discovered it's speeding up. By next summer, expect some record-b...| GOOD
Low Earth orbit, where most satellites operate, has become a whirlwind of metal shards and dead, tumbling debris. Anyone with hardware or human crew in orbit knows the drill. Orbital collision warnings can be unremitting. Whether the object is a defunct satellite or a stray hunk of glass from a solar panel that shattered long ago, every item circling Earth is also a potential projectile. And nearly all of this junk, traveling at least eight times as fast as a rifle bullet, can be damaging in ...| IEEE Spectrum
Using satellites to provide cellular coverage has attracted significant attention recently, with major carriers releasing high-profile announcements on the new service and satellite internet providers purchasing wireless spectrum.

Z-Sat is a microsatellite by Mitsubishi Heavy Industries that was launched in 2021. It is a demonstrator for multi-wavelength infrared Earth observation technologies. It carries an amateur radio payload that was coordinated by IARU and which consists of a BBS (bulletin board system) with a 145.875 MHz downlink and 435.480 MHz uplink. I have not been able to find more information about the amateur radio payload on this satellite.| Daniel Estévez

A CanSat is a small sensor payload, about the size of a soda can, designed to be launched on a model rocket to relatively low altitudes of around 1km. But while that isn’t anywhere close to leaving the atmosphere, it is very high and CanSats need a way to get back to the ground safely. […]| Arduino Blog

We built a platform that aims to automatically address many data quality issues, what one might call a Master Data Management (MDM) system in enterprise data management circles but focusing on sensor data. For imagery, many use cases from creating mosaics to change detection and various other deep learning applications require these data corrections for best results.| Bora Beran
The International Dark-Sky Association, representing astronomers all over the world, lost its appeal regarding the decision of the Federal Communications Commission to grant SpaceX a license to launch tens of thousands satellites without performing an environmental review.

LEV-1 is a small lunar hopper that was carried by the SLIM lunar lander. It was released a few metres above the surface on January 19, as part of the lunar landing of SLIM. LEV-1 transmits telemetry in the 435 MHz amateur satellite band (it has an IARU satellite coordination approval), and also in S-band. Shortly after the landing, CAMRAS received the 437.410 MHz signal from LEV-1 using the 25 m radiotelescope at Dwingeloo. They have published a couple of IQ recordings in their directory of m...| Daniel Estévez
MOVE-II is a cubesat from Technical University of Munich that was launched in December 2018. It transmits telemetry in the 145 MHz amateur satellite band using a protocol that uses CCSDS LDPC codewords. Back in the day, there was a GNU Radio out-of-tree module developed by the satellite team to decode this satellite. Given the additional effort required to support LDPC decoding for just this satellite and since there was already a GNU Radio decoder available, I never added a decoder for MOVE-...| Daniel Estévez
