GRAPE and DemoGRAPE KO meeting,INGV, Rome 9-10 October 2014

Summary

• GRAPE current status (2012-2014)• Future activities

• GRAPE and the SCAR Antarctic and Southern Ocean Science Horizon Scan (Priorities for Antarctic Sciences)

• DemoGRAPE pilot project • GRAPE meeting 2015 and contribution to the URSI AT-RASC, Gran Canaria,

Spain, 2015• Contribution to the ISAES XII - 12th International Symposium on Antarctic

Earth Sciences, Goa (India), 13 July - 17 July 2015

• Create and maintain distributed networks of specialized GPS/GNSS Ionospheric Scintillation and TEC Monitors

• Identify and quantify mechanisms that cause scintillation and control interhemispheric differences, asymmetries and commonalities

• Develop ionospheric scintillation climatology, tracking and mitigation models to improve prediction capabilities of space weather.

• Retrieve tropospheric PWV for input to weather forecast models and to develop regional PWV climatology for atmospheric sensing in remote areas.

GRAPE main objectives:

• WG1- Solar-Terrestrial interactions and ionospheric effects in the current solar-cycle (chair: Paul Prikryl- Canada, co-chair: Emilia Correia- Brazil)

• WG2-Lower atmosphere delay in GNSS based systems

(chair: Monia Negusini – Italy)

• WG3- Modelling and models testing(chair: Cathryn Mitchell UK, co-chair Marcin Grzesiak, Poland)

• WG4- GNSS Data management strategy.(chair: Vincenzo Romano-Italy, co-chair: Pierre Cilliers-South Africa)

• WG5-Coordination with other programs inside and outside SCAR (chair: Maurizio Candidi Italy)

The project will realize a demonstrator, DemoGRAPE, to provide on selected case studies an empirical assessment of the delay and of the corruption induced by the ionosphere on satellite signals in the Antarctic regions. Countries involved: Italy, South Africa and Brazil

• Strong potentialities offered by fully software GNSS receivers for scientific purposes:

• flexibility• configurability• block structure: capability to test

different algorithms
