YD/T 6658-2026 is the English-translated version of 北斗短报文与互联网应用互通技术要求.

YD/T 6658-2026 sets out the general technical requirements for message interworking between BeiDou short messages and the internet. It is based on internet applications and the BeiDou-3 short message network. The document applies to the scenarios in which internet users send and receive messages through the BeiDou satellite messaging service.

The standard is used by internet application developers, BeiDou service and network operators, and the equipment and platform suppliers who build the interworking functions. It is a voluntary standard, as shown by the /T in its code. It was issued by the Ministry of Industry and Information Technology on 11 March 2026 and takes effect on 1 June 2026. It is a new standard. It sits alongside the document on the overall requirements for integrated BeiDou satellite-ground communication, but concentrates on the link between satellite short messages and internet applications.
