Assisting a global navigation satellite system using a local broadcast network

Abstract

Supplementary information for global navigation satellite systems help to improve accuracy, may accelerate a first fix, and could enable localization even in difficult reception scenarios. Contemporary broadcast systems based on datacasting ease implementation of add-on services besides the actual video and audio services. This paper details on the aspects of such services designed for digital video broadcasting for handhelds (DVB-H) in a single frequency network to supplement a global positioning system receiver (GPS). Multiple approaches involving differential and assisted GPS as well as high and low level signalization in DVB-H are analyzed in this paper. From the corresponding results recommendations concerning the implementation of such services are derived

Mediating Multimedia Traffic with Strict Delivery Constraints

“…This approach is currently influencing the Hybrid Broadcast Broadband TV standardization process [3]. Furthermore, in [6] the authors focus on broadcasting augmentation data for GPS, especially on the distribution of such data via IP datacasting.…”
