This article details a fascinating project where a researcher successfully used signals from the NISAR radar-imaging satellite to create a passive radar system. By utilizing the satellite's L-band chirp signal, reflected off the landscape, and comparing it to a direct signal, a topographical image could be generated. The setup involved using GNSS antennas and an SDR (Software Defined Radio) with a Raspberry Pi to record and process the signals. While not producing high-resolution images, the experiment successfully demonstrated the feasibility of using satellite signals for passive radar, even with relatively simple and inexpensive equipment.
A gateway that bridges Meshtastic mesh radios and Iridium SBD satellite modems. Send messages between off-grid mesh networks and global satellite coverage from a single box.
MySat is a fully functional small satellite (CubeSat) STEM kit for space fans. It allows users to build, program, and operate a real satellite system on the ground, providing hands-on experience with space technology.
The PUNCH mission, involving four small satellites, aims to observe the Sun’s corona and its transition into the solar wind over a two-year mission. This will help scientists predict space weather events and their impacts on Earth and space explorations.
Provides access to GOES satellite images and data for regions in North America, the Caribbean, Pacific, and South America, including various channels and composite views for monitoring weather phenomena.
This article provides a guide on how to receive weather satellite images using SatDump.
