ISO/IEC 24730-2由一个主要文件和两个附加部分组成，即ISO/IEC 24730-21和ISO/IEC 24730-22，并定义了一个提供X-Y坐标和数据遥测的网络定位系统。该系统利用实时定位系统（RTLS）发射机，自动生成直接序列扩频无线电频率信标。这些设备可以现场编程，并支持可选的励磁机模式，允许修改RTLS设备的位置更新率和位置。 ISO/IEC 24730-2定义了这些模式，但没有定义实现这些模式的方法。 ISO/IEC 24730-21:2012规定了使用单个扩展码并采用差分二进制相移键控（DBPSK）数据编码和二进制相移键控（BPSK）扩展方案的发射机。

ISO/IEC 24730-2 is comprised of a main document and two additional parts, ISO/IEC 24730-21 and ISO/IEC 24730-22, and defines a networked location system that provides X-Y coordinates and data telemetry. The system utilizes real-time locating systems (RTLS) transmitters that autonomously generate a direct sequence spread spectrum radio frequency beacon. These devices can be field programmable and support an optional exciter mode that allows modification of the rate of location update and location of the RTLS device. ISO/IEC 24730-2 defines these modes, but does not define the means by which they are accomplished. ISO/IEC 24730-21:2012 specifies transmitters operating with a single spread code and employing a differential binary phase shift keying (DBPSK) data encoding and binary phase shift keying (BPSK) spreading scheme.
