Pants for Birds Releases ADSBee m1421, a Small Dual-Band Open-Source Aircraft Tracker
Key points
- ADSBee m1421 is a new dual-band ADS-B receiver.
- It supports Mode S and UAT, including TIS-B traffic and FIS-B weather.
- The device weighs under 2 grams and consumes less than 60mW.
- Firmware and schematics are open source under GPL v3 license.
Introduction of ADSBee m1421
Pants for Birds has launched ADSBee m1421, an addition to its ADSBee family of open-source ADS-B receivers. This new product is specifically designed for aircraft detect and avoid applications, offering a more compact and power-efficient solution.
Technical Specifications and Features
The ADSBee m1421 provides dual-band ADS-B reception, covering both Mode S and UAT protocols. It also supports UAT uplink protocols for TIS-B traffic and FIS-B weather. The device measures 23.4 x 14.5mm x 2.7mm, weighs less than 2 grams, and draws under 60mW of power, making it suitable for mass and power-constrained embedded applications.
Open-Source Design and Integration
Both the firmware and schematic for the ADSBee m1421 are open source, released under a GPL v3 license. Its design as a solder-down module facilitates integration into custom PCB designs. The aircraft position decoding and tracking logic are unified with the existing ADSBee 1090 firmware, and it supports output protocols including GDL90, MAVLINK1, and MAVLINK2.
Technological Advancements
The development of ADSBee m1421 was enabled by Semtech's LR2021 chip, which integrates a high bit rate OOK reception RF frontend and demodulator. This chip, combined with TI’s CC1314 RF MCU, allowed for a significant reduction in form factor and power dissipation compared to previous designs like the ADSBee 1090U.
