List of Satellite Frequencies by Band
VHF Band
- 136 – 138 MHz: This band was used heavily by many different types of satellites in the past. Today (2023), most activity is restricted to 137-138 MHz (which is the current allocation) and consists of meteorological satellites transmitting data and low-resolution images, together with low data rate mobile satellite downlinks (eg Orbcomm)
- 144 – 146 MHz: One of the most popular bands for amateur satellite activity. Most of the links are found in the upper half of the band (145 – 146 MHz).
- 148 – 150 MHz: This tends to be used for uplinks of the satellites that downlink in the 137 – 138 MHz band.
- 149.95 – 150.05 MHz: This is used by satellites providing positioning, time and frequency services, by ionospheric research and other satellites. Before the advent of GPS it was home to large constellations of US and Russian satellites that provided positioning information (mainly to marine vessels) by use of the Doppler effect). Many satellites transmitting on this band also transmit a signal on 400 MHz.
- 240 – 270 MHz: Military satellites, communications. This band lies in the wider frequency allocation (225 – 380 MHz) assigned for military aviation.
