Recently, Cameron Paczek has created a new project called SkyLight, where art meets technical implementation by displaying a live view of aircraft flying overhead on your ceiling. SkyLight consists of a projector, Raspberry Pi 5, RTL-SDR dongle, and some custom software. The Raspberry Pi 5 and RTL-SDR receive live ADS-B data from local aircraft, and […]
Thank you to Christian from ebcTech for writing in and sharing with us that their Dump1090 app for Android has recently been completely redesigned. We first posted about this app back in 2021. The developer notes that the V2 redesign is faster and has an improved UI. The app allowes users to use an RTL-SDR […]
If you’re into airplanes, you’ve probably had the experience of hearing an unusual aircraft and rushing outside to try and catch a glimpse of it, all while fumbling with a …read more
Over on his blog, Zoltán Papp and team have created an interesting write-up investigating whether Semtech's LR2021, one of the latest LoRa transceiver chips, which draws only 10.4 mA at 3.3V, can be used as a single-chip ADS-B receiver at 1090 MHz. The LR2021 natively supports OOK modulation, and the datasheet even hints at ADS-B […]
Over on Kickstarter, Lambda58 LLC has released a campaign for their PicoADSB product, a self-contained 1090 MHz ADS-B receiver that replaces a typical SDR plus Raspberry Pi feeder setup with a single SD-card-sized PCB measuring 25mm x 15mm and weighing only 3 grams. At the time of this post, the campaign has reached around $12,700 […]
The following is a guest post submitted by Matt Larson. The post explains how Matt Larson set up an automated atmospheric wind-sensing station using only locally obtained ADS-B data from an RTL-SDR. Matt's code is available on GitHub. Listening to the Jet Stream - 100 Days of Wind Sensing with Stock RTL-SDR Hardware By Matt […]
Over on GitHub, John Stockdale has released ADS-B Scope – T-Display-P4, a portable open source 1090 MHz ADS-B firmware for the LILYGO T-Display-P4, which is a smartphone-shaped handheld microcontroller with a 4" touchscreen, GPS, SD card, SX1262 LoRa, and a USB 2.0 host port, built around the dual-core 360 MHz RISC-V ESP32-P4. The most interesting […]
Over on GitHub, Martin (mgrone) recently released stream1090, a new open source C++ Mode-S demodulator that takes a fundamentally different approach to finding aircraft messages. Rather than searching for the traditional preamble pulse sequence as dump1090 and readsb do, stream1090 continuously maintains shift registers and identifies valid messages based on their CRC checksum. In busy airspace…
Over on his blog, cynicalGSD has written a detailed post about how he extended his home ADS-B flight tracking setup to also decode ACARS. His existing system runs an RTL-SDR dongle on a Raspberry Pi feeding a database and Flask web app. Adding ACARS required a second RTL-SDR and a separate VHF dipole antenna tuned […]
Thank you to Cameron from BlackAtlas LLC for submitting their project GridDown, which is an open source Android tablet-based situational awareness system designed to operate without an internet connection. At its core, it appears to be a tablet with custom software, and then you can add sensors such as an RTL-SDR for ADS-B+Remote ID, a […]
