Feature Guide: RD File Streaming Over Ethernet

Overview

The Raw Data (RD) File Streaming feature enables you to output RD files directly over Ethernet in the XCOM format. This allows you to stream raw data in real time to a connected computer or logger, rather than storing it internally on the device.

By using RD file streaming, you can simplify and accelerate your post-processing workflow — removing the need to manually copy RD files from the device via FTP after each mission. Instead, all required data is captured and stored directly on your host machine for immediate use in NAVsolve CMD or other post-processing tools.

Raw data streaming requires 3 main steps:

• The Raw Data Streaming feature code enabled on the device.
• Advanced commands in the configuration to output the RD stream in XCOM.
• Processing the XCOM file in NAVsolve CMD.

This flow chart shows the steps that are detailed below.

Configuration

The Raw Data Streaming feature can be enabled on any OXTS unit (XBNS or RTBNS) running firmware version 151203 or newer.

To configure RD file streaming, the following command must be added to the configuration: 

-xcom_rd

This command enables the transmission of RD file data within the XCOM packet container, allowing the raw data to be streamed over Ethernet.

This can be added:

• In the Advanced → Commands section of NAVconfig.

• Directly to the mobile.cfg file.

Logging the XCOM

Once these are added to the configuration, the unit will start outputting on UDP port 50475; this binary data can be logged in Wireshark but the file extension will need to be changed to .xcom before it can be processed.

Post processing

Refer to the NAVsolve CMD User Guide for post-processing data.

NAVsolve CMD automatically detects the RD stream within the XCOM file, hence there is no difference in workflow between processing XCOM and a standalone RD file.
