Version 2.1 of the BeiDou Navigation Satellite System Signal In Space Interface Control Document for the Open Service Signal has been released.

The document was issued by the China Satellite Navigation Office. It defines the specification related to open service signals B1I and B2I between the space segment and the user segment of the BeiDou Navigation Satellite System. B2I will be gradually replaced by a better signal with the construction of global system.

Signal analysis from the Z-Wave Alliance Unplugfest event in Carlsbad, California, on Oct. 28, 2025, shows the current real-world noise floor and peak Part 15 signal power in a typical suburban environment. Analysis from Pericle Communications estimates Part 15 signal strength would need to be at least 538 times and up to 741 million times greater to achieve equivalent link reliability if NextNav’s proposed high-power downlink band is approved.
