Hi everyone! I'm newbie here, while I was researching about model rocket studies, I found this forum and signed up here Here are lots of information and I want to follow them always. However, I want you to guide me for our student project. We are a team which is a competitor for international and national(in Turkey) organization about Model Rocket and Satellite. In the last year, we built successfully a model satellite for CanSat Competition, and this year we applied for a competition about Model Rocket. We are electronics and mechanics engineering students and we love R&D. So we could design our flight computer(board) and telemetry. Now, we want to improve our design, can you guide me to lead my team? Our components for the first draft: 1. Teensy 3.5 (Dev. Board) 2. BMP180, MPU9265, LM35 (Sensors and Modules) 3. UBLOX NEO 6M GPS 4. XBee 2.4 GHz RP-SMA 63mW Transciever Modules Our questions: 1. Where is the best location for antenna? 2. Which type of antenna is the best for rocket? 3. How can we improve/amplify our telemetry signals? (in Ground or in Probe) Our rocket must carry more than 4kg payload and its maximum altitude will be 3000+-100 meter. Thank you.
