Abstract: The Ionosphere total electron content (TEC) active broadcasting technique using location and cloud computing as well as a platform is proposed in this article. Consisting of physical and virtual servers, the scientific computing and user interface are separated in this technique. Thus, physical servers bring computational efficiency into full play so as to improve the platform's performance. The platform configuration can be adjusted to the number of users for cost savings. With multiple virtual server backups, it maintains the stability and security of the platform. Also, the platform has effective control over the precision of TEC in specific space-times. It can serve regional or global users according to different demands. Users can request TEC by internet, mobile internet, and application programming interfaces to correct ionospheric delay for precise positioning. The ionosphere modeling methodology and users can be separated by this pattern of broadcasting. So users just receive ionosphere TEC broadcasted by the platform, not the ionospheric model's coefficients. It mitigates complexity of receiver data processing, and promotes uniformity.
