Serial Communications for Ground Control


The U.S. Navy’s arsenal includes a jet-powered, long-range cruise missile that receives real-time, in-flight guidance via SATCOM. This communication enables the missile to dynamically track and engage targets. This capability is extremely valuable as it can take some time for the missile to reach a designated target.

An aerospace prime contractor contacted Sealevel to explore options for serial communications adapters to provide the connectivity for the communication and navigation in the ground control guidance system.

The Sealevel Solution

Based on the specified requirements, Sealevel recommended our 5102e and 7106e PCI Express Serial Communications Adapters.

The 5102e allows for maximum compatibility with a variety of interfaces and protocols. Intended for communications, avionics, navigation, and radar applications, the 5102e provides robust synchronous communications. This multi-interface board is fully configurable and features a digital phase lock loop (DPLL) circuit for increased reliability when using NRZI or RM encoding.

With its ultra-high-speed UART, flexible clock prescalar, and large 256-byte Tx/Rx FIFOs, the 7106e is able to support a wide range of baud rates, making it ideal for data-intensive applications that require fast and reliable throughput rates. And for rapid trouble-shooting, the onboard LEDs indicate status, electrical interface, and line termination.
