In Sep 2012 the satellite experienced a malfunction with its sounder due to a motor vibration and was brough offline. It could be fixed in mid October. Another incident occured in May 2013 (probably a micrometeroid which hit the arm of a solar panel array).

Was taken over in 2020 after a backup period by the DoD (purchased) and relocated at 61.5°East and renamed EWS-G1 (Electro-Optical Infrared Weather System) in Sep 2020 as it was declared operational.

SXI (Solar X-ray Imager)

Carries a new Solar X-ray imager (SXI). It was designed and built by Lockheed Martin Space Systems.

A prototype SXI was developed, tested, and calibrated and launched aboard the GOES 12 satellite in July 2001. The new SXI has a factor of two greater spatial resolution than the prototype, and like some high-end home video cameras, it has active internal jitter compensation that provides a stable picture even when the spacecraft is moving. Additionally, more sophisticated computer control allows SXI to react automatically to changing solar conditions.
The imager maps the X-ray emitting regions on the Sun in the bands 0.6-3.0 and 0.6-6.0 nm, once per minute.


The new Image Navigation and Registration (INR) system will use star trackers to provide precision image navigation and registration information for use with the Imaging and Sounding data products. This will improve precision.
