A single S-band boom antenna on each satellite (deployed after launch by a pyrotechnic device) enables the satellite to communicate with Earth . There are small backup antennas on the top of each satellite to provide backup communication as required.

WMO is concerned about this as the use of the 2.7–2.9 GHz frequency (S-band) by meteorological radars is critical for weather monitoring and prediction applications.
Read moreWhat is the difference between S band and C band?
It is not uncommon for a S band dish to exceed 25 feet in size. C band radars operate on a wavelength of 4-8 cm and a frequency of 4-8 GHz . Because of the wavelength and frequency, the dish size does not need to be very large. This makes C band radars affordable for TV stations.
