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. ANPP is proprietary and is used across all Advanced Navigation products. A packet type can be identified by its unique Packet ID. For more information about packets, see About Packets.
The following packet types are available:
- System Packets - These packets have ID values of less than 20.
- State Packets - These packets have ID values between 20 and 179.
- Configuration Packets - These packets have IDs greater than 179.
