What orbit do BeiDou-3 IGSO satellites use?

BeiDou-3 IGSO (Inclined Geosynchronous Orbit) satellites orbit in a figure-eight ground track pattern centered over the Asia-Pacific region. This specialized orbit keeps the satellites spending most of their time over the areas where enhanced navigation coverage is most critical.

What region does BeiDou-3 IGSO primarily serve?

BeiDou-3 IGSO satellites provide enhanced signal coverage focused on the Asia-Pacific region, where China's navigation needs are most concentrated. They complement BeiDou-3 satellites in medium Earth orbit and geostationary orbit to form a complete global system.

When was the BeiDou-3 constellation completed?

The BeiDou-3 global navigation constellation was completed in 2020, making China the third entity after the United States (GPS) and Russia (GLONASS) to operate a fully global satellite navigation system. The IGSO satellites are key components providing regional enhancement over Asia-Pacific.

What is the role of BeiDou-3 IGSO satellites within the broader BeiDou system?

The IGSO satellites enhance positioning accuracy and signal availability specifically over the Asia-Pacific region, where China has the greatest strategic and economic interest. They work alongside medium Earth orbit satellites that provide global coverage and geostationary satellites for regional services.
