WebbSome satellites feature Argos 3, with varying degrees of functionality. The Argos 3 system features a new downlink signal at 465.9875 MHz. However, due to ground-based alarm system interference issues in the United States, the downlink was disabled on the NOAA-19 satellite. Other newer satellites still transmit on this frequency. Satellite communications are conducted over a wide range of frequency bands. The typical bands considered for small satellites are UHF, S, X, and Ka. The most mature bands used for CubeSat communication are VHF and UHF frequencies. Visa mer The communication system is an essential part of a spacecraft.
