Preface to the Special Issue on the Macau Science Satellite-1 Mission by Dali Kong

“…MSS-1 consists of two satellites that are to be launched in the near future. Since these two low Earth orbit (LEO) satellites will operate in circular orbits, with an inclination of about 41°, they are expected to provide essential measurements covering the Earth’s lower-latitude regions—including, especially, the South Atlantic Anomaly (SAA). …”

Design of Wide-Band Microstrip Antenna for S-Band Telemetry Applications by Pushpalatha M, Namana N, T. S. Navadagi, Varun D

“…The proposed design explores the concept of wide-band antenna with improved omnidirectional gain and smaller size essentially aiming at low-earth orbit (LEO) satellite telemetry. The proposed partial annular radiating patch design has an operating impedance bandwidth ranging from 2.7 GHz to 3.8 GHz with a percentage bandwidth of 31%. …”
