BeiDou-LogoThe interface control document (ICD) describing the details of the BeiDou B1I open service signal on 1561.098 MHz was released December 27 at a news conference held in Beijing by the Chinese State Council Information Office. Download the English version here. The ICD specifies the relations of the signal in space interface between BeiDou Navigation Satellite System and users’ terminal receivers. It is the essential technical document to develop and make receivers and chips.

Anyone who has questions about the ICD is invited to submit them to this email: BeiDouICD@beidou.gov.cn

The document, BeiDou Navigation Satellite System Signal In Space Interface Control Document — Open Service Signal B1I (Version 1.0), includes a system introduction, signal standards and navigation message, which defines the related contents of the open-service signal B1I between the BeiDou Navigation Satellite System and users’ terminals.

In a previous presentation given at the Seventh Meeting of the International Committee on Global Navigation Satellite Systems (ICG) held in Beijing November 5-9, 2012, BeiDou officials stated that by 2020 there will be five GEO and 30 non-GEO satellites. The number of IGSO and MEO satellites isn’t stated, but previous presentations have said three IGSOs and 27 MEOs. This is also stated in the official ICD.

Goodbye, Compass. At the news conference, Ran Chengqi, the director of the China Satellite Navigation Office, announced that the English name of the system is henceforth the BeiDou Navigation Satellite System. A new, slightly modified logo for the system was also introduced by Ran. The new version drops the parenthetical “Compass” translation of BeiDou.

Also, the China Navigation Satellite Office now has a new English-language website.
