Part Ⅲ Contribution to GNSS
1. Unique Development Pattern
Form the development philosophy of Region
highlighted, Global service and Distinguished
features.
Explore the roadmap of gradual development.
Adopt the integration method of passive
position and short message communication.
2. Innovative Technology
Design hybrid asymmetry constellation:

realize application step by step.
Provide triple frequency signals.
Optimize system mechanism by uniting RDSS,
RNSS and Wide-area differential services.
3. Numerous Application Occasions
Having service capability in Asia-Pacific region, provide numerous choices of multi-systems compatible application.
Having service capability of triple frequency navigation signals, expand innovative chances of high-precision application.
Having integrated service capability of RNSS and short message communication, support diversified application.
ConclusionsBeiDou Construction The second deployment step has been
accomplished. BeiDou will possess full operational capability
early next year. BeiDou is expected to enter into comprehensive
operational service stage.BeiDou Application BeiDou chips is matured day by day. Application is promoted in large scale. ICD (formal version) is to be released to
support industry development .
Conclusions
BeiDou International Activity
Carry out international exchange, coordination and cooperation.
Carry out BADEC, promote multi-GNSS fusion applications.
Speed up the construction of iGMAS, support international monitoring and assessment to ensure reliable GNSS services for global users.
