The TT-SU2 OEM ADS-B/GNSS & UAT Receiver is a compact OEM receiver designed for the reception and decoding of aviation surveillance and positioning signals at 1090 MHz and 987 MHz. Developed around the proprietary FPGA-In-The-Loop™ architecture, the module combines a single-core processor with FPGA-based processing to deliver rapid RF data handling while minimizing component count. This approach enables a compact form factor suitable for embedded integration where size, system complexity, and cost are important considerations. The module supports ADS-B, Mode A, Mode C, and Mode S signal reception and decoding, providing a versatile solution for aviation and uncrewed systems applications.
Designed for straightforward OEM implementation, the TT-SU2 provides signal power and quality analysis together with timestamping capabilities that can support multilateration-based developments. A high-speed UART interface and AT-command configuration simplify integration into existing platforms and subsystems, while additional interfaces enable firmware adaptation and application-specific functionality. Optional communication interfaces, protocols, and specialized features are available for projects requiring tailored performance, making the TT-SU2 suitable for a broad range of airborne, ground-based, and unmanned systems deployments.
