Chunghwa Telecom and Singapore Telecommunications (SingTel) are considering collaborating once again to launch a second satellite to replace ST-1, which was deployed in 1998. ST-1, which serves ships and remote sites in Tibet and Bhutan, and oil rigs in Papua New Guinea, is expected to stop functioning within a few years, when its service life expires. According to SingTel, the new satellite, which is expected to cost around $250-300 million, will accelerate the connection speed up to four times.
