1. Receive and demodulate AIS (Automatic Identification System) signals sent by ships to an experimental AIS receiver on the spacecraft MaxValier and retransmit those data to the earth over an S-Band link 2. Testing the behavior of ORBCOMM and IRIDIUM modems in space More information from http://www.gobbz.it/ **Downlinks on 145.860MHz and 145.960MHz have been coordinated** **Now planning a Q2 2106 PSLV launch into a 500km SSO with 0930 LTAN** ** A single beacon on 145.860MHz is now planned and the launch date is advised as June 10th 2016****Launch has been delayed to a later flight**

a) The advanced technology AIS (maritime Automatic Identification System) receivers in order to get AIS data from space and to study the AIS signal reception in LEO; b) Intersatellite link experimental systems for the two way, near real time, permanent communication via Orbcomm and Iridium LEO based satellite systems; c) Plug-and-play electronics unit with new data handling systems, sensors and beacon to a geostationary satellite system; d) Small onboard camera with advanced optics for low resolution earth monitoring. For the telemetry and telecommanding needs the satellite will have a HAM ground station in Ventspils, Latvia. The AIS data will be downloaded via a dedicated S-band link, where the frequency coordination is in progress as for a scientific earth observation or communication satellite via ITU. The Orbcomm links provide the spacecraft safe mode communication possibilities and are based on previously flown Rubin missions by the University of Applied Sciences and OHB-Systems AG company in Bremen,
No lasītā rodas iespaids, ka tā AIS daļa abiem ir ļoti līdzīga. Labi, ja ticam ļoti cienījamiem cilvēkiem, Venta-1 nebija naudas palaišanai. Bet kāda velna pēc tas itāļu Max Valier arī tiek visu laiku marinēts uz Zemes?
