SBAS Transmission Service

This service transmits the SBAS (Satellite-Based Augmentation System) signal which used with GEO satellites to provide augmentation information about range error corrections and navigation satellite anomaly to aircrafts, etc. It can be used on SBAS (L1Sb) receivers.

SBAS signals are also transmitted in North America, Europe, and other regions as well as Japan, and are operated with authorization by the aviation safety authorities of each country as a system for aircrafts. It is possible to set safety and efficient air routes in order to be able to navigate accurate aircraft positions by the SBAS.

SBAS is highly reliability because it is authorized by aviation safety authorities. In addition, SBAS is increasingly used in non-aviation fields such as ships and cars, since an international standard has been defined For example, many car navigation systems on the market are "the SBAS supported".

In Japan, the SBAS signal is currently transmitted from MTSAT (Multi-functional Transport Satellites) operated by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). The SBAS signal that is made by MLIT is planned to be transmitted from QZS on a GEO using the QZSS SBAS transmission service from around 2020.
