Stackable Data Acquisition & Telemetry Suite

TUALCOM’s data acquisition and telemetry suite uses a stackable architecture, allowing multiple modules to be combined within a compact and uniform footprint. This approach supports flexible configuration based on mission requirements and available integration space.

The telemetry modules provide UART outputs for real-time data monitoring, while a proprietary high-speed internal bus enables reliable, low-latency communication between modules. Data acquisition units support a range of digital and analog interfaces, including Ethernet, serial connections, and high channel-count sensor inputs.

Telemetry Receiver

The TUALRX receiver is designed to capture PCM-FM telemetry signals within the 2.2 to 2.4 GHz band, supporting data rates up to 16 Mbps. Output is provided via Ethernet, with compatibility across multiple decoding formats.

A portable configuration is available for field use, incorporating an integrated display and processing capability for real-time telemetry visualization and analysis during testing activities.

Telemetry Transmitters

Flight Termination Transmitter

The Flight Termination Transmitter is a ground-based unit that generates termination commands using IRIG-defined tone sequences transmitted via FM signals within the 390 to 450 MHz band. Operators can configure tone sequences, operating frequency, and SAFE, ARM, and TERM functions via PC interface using RS 232.

The system is compliant with RCC 319 requirements and is suitable for integration into both fixed and mobile range safety installations. It is built to MIL-STD-810G environmental standards and includes reverse polarity protection.

Flight Termination Receiver

The Flight Termination Receiver functions as a tone decoder for termination systems, using a superheterodyne architecture with programmable center frequency. It supports decoding of three or four tone sequences selected from 20 IRIG tones.

Features include loss-of-tone detection, low voltage protection, cross strapping capability, and signal strength telemetry output. The system meets RCC 319-14 and RCC 313-01 standards and is qualified to MIL-STD-810G.

Flight Termination System

The Flight Termination System is an integrated solution that provides a redundant command capability for range safety operations by transmitting termination commands to airborne receivers when required. It allows real-time switching between channels to maintain continuous communication with airborne assets during flight testing or tactical operations.

The system includes dual control panels, dual power supplies, a central control unit, and an antenna switching unit capable of supporting up to eight antennas. The architecture is designed to enhance reliability in critical safety scenarios.

Active Radar Reflector

Operating across 5 to 18 GHz, the TUALARIA active radar reflector receives, amplifies, and retransmits radar signals at a programmed radar cross-section level. It supports operation across C, X, and Ku bands, with selectable RHCP or LHCP spiral antenna configurations.

An adjustable attenuator, configurable via RS-232, allows tuning of radar return characteristics to meet specific training or testing requirements.

ESM/ELINT Receiver

The TUALCOM ESM/ELINT Receiver captures radar emissions within the 2 to 18 GHz range and generates Pulse Descriptor Words (PDWs), including parameters such as frequency, amplitude, pulse width, time of arrival, and PRI. Data is transmitted via Gigabit Ethernet.

The receiver includes four RF input channels to enable direction-finding capability, along with LVDS interfaces for control and telemetry. Filtering options include both switchable multiplexing and configurable digital filters.

Compact IFM Receiver

The Compact IFM Receiver operates across the 2 to 18 GHz frequency range, producing PDWs with key signal parameters such as frequency, amplitude, pulse width, and time of arrival. Output is delivered via Gigabit Ethernet, with an additional LVDS interface for system control.

The system is capable of generating more than 2 million PDWs per second and incorporates advanced filtering techniques for improved signal discrimination.

Radar Altimeter

The FPGA-based Radar Altimeter provides accurate above-ground level measurements for airborne platforms. Its compact and lightweight design supports integration where SWaP constraints are critical.

The system is capable of operation at speeds up to 1.5 Mach and includes built-in self-test functionality. It is suitable for all-weather use and can be integrated into both modern and legacy avionics systems.
