TeLEOS-1 IN MULTI-SOURCE MARITIME SECURITY AND SAFETY APPLICATIONS

摘要

Riding upon the success of X-SAT launched since 20 Apr 2011, ST Electronics (STEE) has embarked on small satellite manufacturing through its ST Electronics - Satellite Systems, a joint venture company. STEE is currently developing TeLEOS-1, Singapore's first commercial Earth observation satellite to be launched in Near Equatorial Orbit (NEqO) in Q4 2015. TeLEOS-1 differentiates itself from the world players of Earth Observation satellites in Sun Synchronous Orbits by providing high responsiveness and high availability data by nature of its low inclination orbit at 15 degrees. However, this is achieved at the expense of foregoing global coverage for equatorial belt coverage. The equatorial belt covers many major shipping routes. TeLEOS-1 imagery is especially applicable for maritime security and safety, a business application which many service providers are offering in conjunction with AIS correlation for vessels. STEE - Satcom & Sensor Systems aims to be a commercial service provider in value-added geospatial services using multiple satellite imagery sources together with TeLEOS-1 in the mix for effective surveillance, classification and identification of vessels over global coverage through fusion with Automatic Identification System (AIS) as well as information from vessel traffic management system and port information system for a near real time recognised maritime situation picture. Besides the TeLEOS-1 S-400 bus, STEE also has the SS-150 bus in partnership with ATK of USA for microsatellites of less than 200 kg mass. One or more electro-optical microsatellites in NEqO constellation can supplement the user's capability for enhanced maritime security and safety. The specifications of SS-150 and S-400 buses will be introduced.
