TeLEOS-1: First Commercial Earth Observation Satellite in Near Equatorial Orbit

摘要

TeLEOS-1, Singapore's first commercial Earth observation satellite was launched into a 15° inclination Near Equatorial Orbit (NEqO) on 16 December 2015 by ST Electronics (STEE). By end June 2016, it has successfully undergone six months of in-orbit test for camera calibration of its high resolution panchromatic imagery. TeLEOS-1 with an orbital period of 96 minutes with up to six daylight passes per day over its ground station, can deliver high responsiveness coverage to the equatorial belt. TeLEOS-1 is geared for applications such as maritime security and safety, environmental monitoring, humanitarian assistance and disaster relief and infrastructure development planning and monitoring. A near equatorial orbit also allows coverage of the gaps in STEE's partner sun synchronous satellites for a well-rounded portfolio of Electro-Optical (EO) and Synthetic Aperture Radar (SAR) imagery. Commercialisation of TeLEOS-1 imagery services under the "AgilSpace" brand has commenced through the new "AgilSpace GeoPortal", an imagery hub for e-commerce over Internet with embedded simulation of satellite passes over customer's area of interest.
