Integrated Pulse Coded Modulation Encoder (iPCMe)

Invocon’s Remote Power Control (RPC) Remote Ground Support Equipment (RGSE) provides for power control and monitoring for Avionics or Flight Termination System (FTS) payloads. This includes system monitoring, power switching (e.g., internal/external, on/off), and battery maintenance as well as RS422 communications all through the vehicle’s UMBI(s). The rack is controlled remotely via direct Ethernet connection or through a fiber optic converter for extended range.

Key Features

  • 100+ Channel Simultaneous Analog Sampling

    Simultaneously samples 100 analog channels with greater than 15 bits of dynamic range, providing high-fidelity multi-channel data acquisition in a single unit.

  • Fiber PCM Output

    850 nm multimode fiber PCM output supports transmission distances up to 2 km over 50/125 µm fiber, eliminating copper cable mass and susceptibility to EMI.

  • IRIG 106 Chapter 4 PCM

    Outputs a fully IRIG 106 Ch.4 compliant PCM stream with optional minor frame CRC and optional RNRZ-L15 encoding for range telemetry compatibility.

  • Integrated NTSC Video Multiplexing

    Two NTSC video channels are multiplexed into a single JPEG 2000 video output, consolidating imagery data within the PCM stream.

  • PCM Matrix Configuration Software

    Included software tool provides a PCM matrix configuration interface for efficient channel packing, real-time data display, and unit health/status monitoring.

  • Capture Link™ Interface

    Supports Invocon’s KIPS/WKIPS Capture Link™ interface for lethality assessment bandwidth sharing on the PCM stream.

  • Single-Face Connector Layout

    All DB connectors on the top face of the unit eliminate cable routing complexity during integration and reconfiguration.

Typical Applications

  • Launch Vehicle Telemetry

    Encodes and downlinks vehicle health, guidance, and payload data via PCM telemetry over fiber or copper.

  • Range Instrumentation

    Provides IRIG 106-compliant PCM data to range ground systems for real-time monitoring and post-flight analysis.

  • Lethality Assessment / KIPS

    Shares PCM bandwidth with KIPS/WKIPS hit detection systems via Capture Link™ for integrated telemetry.

  • Payload Data Acquisition

    Acquires simultaneous 100-channel analog sensor data for payload instrumentation in space and avionics applications.

  • GPS Timing Distribution

    Redistributes GPS 1PPS across vehicle systems using the dedicated 1PPS input and distribution output.
