Detailed discussions are also expected on UAS (unmanned aircraft system) use of FSS (fixed satellite service) networks. Two regional groups, CEPTCEPT stands for the European Conference of… (Europe) and APTAsia-Pacific Telecommunity (APT) is a regi… (Asia-Pacific), have been unable to form a common position on these items.
