GDP ITC 2025 | Network-Centric Telemetry System Demo

At ITC 2025, GDP demonstrated its Network-Centric Telemetry System, showcasing the company’s integrated approach to modern telemetry acquisition, transport, and recording. Steve Nicolo, GDP’s Business Development Manager, introduced Station 4, which represented some of GDP’s most advanced technologies working together as a single, networked system, including the Model 2267 Best Source Selector (BSS), Model 2355 TMoIP Gateway, and Model 3500 Ethernet Recorder. The Model 4455 Digital RF Receiver, also part of this configuration, is featured in greater detail in a companion demo with Joe Deschamp, here. Steve first demonstrated how GDP’s Model 2267 Best Source Selector supports multiple telemetry streams in real time. Recorded data, including RCC DQE/DQM streams from the GDP Model 4455 Receiver, were replayed into several BSS groups, each with a specific multicast IP address routing the data in parallel to each of the four channels in each of three groups. Using the BSS GUI, he showed how the system automatically detects, compares, and selects the highest-quality data source to maintain clean, continuous telemetry output. The team also illustrated live channel switching, where data from the Model 3500 Ethernet Recorder cycled a bad DQM value through channels one to four.  As individual channels were taken offline (bad DQM value), the BSS instantly transitioned to the next available input, ensuring uninterrupted data delivery (no drop-locks on downstream decoms when switching). This closed-loop demonstration showcased the resiliency, automation, and precision of GDP’s network-centric telemetry architecture and the BSS’s ability to manage simultaneous data sources with unmatched reliability and data integrity for range and flight-test operations. In the second portion of the demo, Steve highlighted GDP’s Model 2355 Telemetry Gateway, demonstrating real-time PCM-to-Ethernet and Ethernet-to-PCM conversion. The Gateway featured eight configurable channels, each transmitting or receiving telemetry streams using the IRIG 218 TM-over-IP protocol. Steve configured four active channels to transmit simulated PRN-15 sequences at 35 Mbps, verifying pattern detection, frame lock, and packet reception on both transmit and receive sides. He also showcased the Gateway’s auto-sensing format capability, which automatically detects and adjusts between IRIG 218-10 and IRIG 218-20 formats. This demonstration highlighted how the Model 2355 Gateway simplifies integration between legacy PCM links and modern network-centric telemetry systems, providing high reliability, synchronization accuracy, and end-to-end data integrity across all active channels. Together, these technologies form a fully networked telemetry node that bridges acquisition, transport, and recording within a single, interoperable ecosystem. GDP continues to lead in range modernization through scalable, high-performance solutions built for today’s and tomorrow’s mission-critical environments. Each ITC station was paired with an interactive touchscreen display designed to give attendees a deeper look into the technologies behind every demo. These touchscreens provided a guided walk-through of each system’s components, showcased top products, and highlighted key advantages from the company. Explore the same content for yourself.
