这段代码是一个 Java 类，名为 ProtocolData，其中定义了一个协议数据的结构。它包含了一些常量，例如协议头 PROTOCOL_HEADER，协议分隔符 PROTOCOL_SEPARATOR，协议换行符 PROTOCOL_NEWLINE；以及一些数据字段，例如帧序号 frameNumber，系统状态 systemState，寻北进度 northProgress，航向角 headingAngle，俯仰角 pitchAngle，横滚角 rollAngle，实时数据 realTimeData。此外，它还定义了两个枚举类型 systemState 和 realTimeData，分别表示系统状态和实时数据的类型。最后，它还重写了 toString 方法，将数据转换成字符串。
