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

Mobile devices - like smartphones - usually demand for ultra low power solutions to save battery life. This paper presents a novel approach to receive broadcasted data objects from a data carousel under these extreme low power conditions. The method is demonstrated for the DVB-T2 system using an integrated ultra low current wake-up receiver. The performed simulation suggests that an increased SNR of 0.3 dB is required to decode the modified DVB-T2 waveform. On the other side, this allows for continuous listening for carousel objects at the receiver side. During listening mode the wake-up receiver consumes 230 mu A at 3 V for the simulated configuration
