Abstract
For satellite and UAV applications a radio link is established to receive real time telemetry. This link can be formed using a variety of frequencies and equipment, each with their own pro’s and cons regarding effective range, data rate, and cost. We have developed a high-altitude balloon payload that analyzes these factors by comparing data transmission over two separate frequencies: 900MHz and 2.4GHz. Live video and telemetry will be broadcast over the 2.4GHz frequency. By using a Nivida jetson nano with sensors we can know and see the location of the payload in a 3D space and orientation. Additionally, telemetry will be sent over a 900MHz link using an RFD900+ Modem. These signals are received with high-gain antennas on a tracking ground station. An on-board SD card will also collect this same telemetry data to be compared with what is received. Overall, this experiment will characterize the quality and range of these radio links to guide future university aerospace projects.
