10 Advanced Navigation Packet Protocol

The Advanced Navigation Packet Protocol (ANPP) is a binary protocol designed with high error
checking, high efficiency and safe design practices. It has a well defined specification and is very
flexible. It is used across all existing and future Advanced Navigation products. There is an SDK
available for download from the website with code examples.

10.1

Data Types

The following data types are used in the packet protocol. All data types in the protocol are little
endian byte ordering.
