The future of wireless communication is today being sketched out in the skies and in space. A new generation of intelligent aerospace platforms—drones, airships, and satellites—will be part of tomorrow’s 6G networks, acting as, in effect, base stations in the sky. They’re expected to roll out in the early 2030s. Researchers at the King Abdullah University of Science and Technology (KAUST) in Thuwal, Saudi Arabia, are amid the vanguard of innovators now imagining next-gen telecom netwo...| IEEE Spectrum
Earth’s atmosphere is large, extending out to around 10,000 kilometers from the surface of the planet. It’s so large, in fact, that scientists break it into five separate sections. There’s one particular section that hasn’t received a whole lot of attention due to the difficulty in maintaining any craft there. Planes and balloons can visit the troposphere and stratosphere, the two sections closest to the ground, while satellites can sit in orbit in the thermosphere and exosphere, allo...| IEEE Spectrum

Forest Whitaker may be better known for his decades of film roles, from Fast Times at Ridgemont High to The Last King of Scotland, but it’s his off-screen work that may prove most enduring.

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

Since some years ago, a Doppler correction block has been available in gr-satellites. This block uses a text file that defines a time series of frequency versus time, and applies the appropriate frequency shift to each sample by linearly interpolating the frequency corresponding to the time of that particular sample. It can be used both… Continue reading Time-dependent delay in GNU Radio| Daniel Estévez

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
For a long time, AMSAT-DL has been using the 20 meter antenna in Bochum observatory to receive some telemetry from Tianwen-1, the Chinese Mars orbiter, almost daily. Since the telemetry includes the spacecraft’s state vectors, we can use this to monitor the spacecraft’s orbit. In 8 November 2021, Tianwen-1 entered its remote sensing orbit. This is an elliptical orbit with a period approximately 2/7 Mars sidereal days plus 170 seconds. This causes a ground track that is almost repeating, b...| Daniel Estévez
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
