11 2 THE FireBird MISSION GOALS (2) The two satellite constellation: 1. The TET-1 satellite (launched June,2012) Is now used by the On Orbit Verification Mission of the DLR space administration. After one year in space it changes to the FireBird mission of the DLR R&D program directorate space 2. The BIROS satellite (launched expected 2014) Funding from German Government (satellite BUS) and from DLR R&D program directorate space. TET-1: 60x60x80 cm³, 120 kg, 500 km SSO BIROS: 60x60x80 cm³, 140 kg, km SSO Slice 11

12 2 THE FireBird MISSION GOALS (3) The BIROS satellite gives the opportunity for working on secondary mission goals 1. Optical navigation experiment AVANTI PicoSat launch from BIROS The PicoSat serves as non cooperative target for optical navigation and proximity operations (100m 10 km distance) Inter satellite link PicoSat BIROS permits the usage of the PicoSat GPS receiver as a BIROS remote device for AVANTI verification Relation to primary mission goal: Experiences for a cooperative behavior of different small satellites in future in fulfilling a common task for future mission concepts Slice 12

13 2 THE FireBird MISSION GOALS (4) The BIROS satellite gives the opportunity for working on secondary mission goals 2. On Board Mission Planning experiment VAMOS 1. Special SW in the on the BIROS payload computer 2. A special shadow command list in the BIROS board computer 3. Alternative on board scenarios depending on conditions like Memory usage Battery level Clouds over the target areas Detection of fires in the target region (yes/no) 4. Autonomous decision on board about the mission scenario Relation to primary mission goal: Increased efficiency of an Earth Observation mission by maximizing the usage of on board resources Slice 13

14 2 THE FireBird MISSION GOALS (5) The BIROS satellite gives the opportunity for working on secondary mission goals 3. Optical communication experiment OSIRIS 3 different laser systems for communication to ground data rate up to 1 Gbit/s four quadrant laser detector on board for increased pointing accuracy a beacon laser from ground to satellite supports the BIROS attitude control and can be used for an optical data uplink Relation to primary mission goal: Dramatic extension of downlink capacity comparing it with the standard S-band transmitter of BIROS Slice 14

16 3 THE MISSION POLICY 1. FireBird is a DLR mission all mission segments are controlled by DLR R&D the mission is organized as a DLR R&D project 2. FireBird is a science mission The mission is not focused on commercial aspects The mission is not operational The mission is steered by an Principal Investigator and an international, open science team The mission is open for other EO topics 3. FireBird is an IR mission for remote sensing of high temperature events this is the main goal of the mission but secondary goals are accepted and desired Slice 16
