If you wish to build a deeper integration with our systems for more bespoke solutions, this article will list resources that you may be useful.

NCOM

This is the default format used by OxTS systems and is output primarily over ethernet although it can also be obtained over serial.

• NCOM Manual - Details on the NCOM stream packet structure that is sent out by the system are in this manual
• Sample Decoder - GitHub repository for an NCOM decoder written in C. It contains a list of all the main measurements output by the system.
• Sample NCOM file - Sample NCOM file to test the decoder
• Navigation measurements and their definitions. This document is intended for use with our .NET based SDK, so some of the measurements mentioned do not exist in the GitHub decoder but you will find most the major ones.

You can also replay the NCOM file when testing the utility you are developing with this file replay tool.

NMEA

This popular ASCII format is also output by our navigation systems. While we conform to the NMEA standard you may need to know the exact information contained within each sentence. This can be found in the NMEA Description Manual.

RCOM

For range systems this format is used to transmit calculated range data. The RCOM Manual details the RCOM stream packet structure.

CAN

Some OxTS systems support a CAN bus interface for automotive applications. The CAN Interface Manual details all the messages and their identifiers that can be output by the INS.
