The ITU will approve two new standards for satellite services and revise one other unless objections are raised by Dec. 28, the director of the Radiocommunication Bureau said in letters to members. One new recommendation includes access procedures for fixed-satellite…

service (FSS) occasional use transmissions to geostationary-satellite orbit space stations in the 4/6 GHz and 11-12/13/14 GHz FSS bands, a second letter said. An FSS occasional use transmission is a telecommunication application with a transmission that lasts a limited period of time ranging from minutes to months, it said. Another new recommendation provides a methodology to calculate aeronautical mobile-satellite route service (AMS(R)S) spectrum requirements within the frequency bands 1545-1555 MHz in the space-to-earth direction, and 1646.5-1656.5 MHz in the earth-to-space direction, a letter said. It’s intended to be used to quantify the spectrum requirements related to the AMS(R)S priority categories defined in the Radio Regulations, it said. The 2012 World Radiocommunication Conference called for development of the spec. Editorial changes were proposed for an existing recommendation on broadcasting satellite service Earth station antenna patterns for use in interference assessment involving non-geostationary orbit satellites covered by the FSS regulatory plan for the bands 4500-4800 MHz, 6725-7025 MHz, 10.70-10.95 GHz, 11.2-11.45 GHz and 12.75-13.25 GHz.
