NigeriaSat-2, based on the SSTL-300 platform, was designed to be highly agile and flexible, providing high resolution, accurate data, with fast downlink speeds.
Flexible multi-mode operation: stereo, strip, area mode, fast response
Provides versatile operations such that the spacecraft can be used equally well for routine mapping applications where the important parameter is data throughput (strip mode), as it can for disaster response where it is vital to be able to focus on exact locations in a timely manner.
2.5m GSD Panchromatic imagery at 20km swath width
This mode uses the very high resolution imager to capture detailed images across the globe for disaster response, land use monitoring, and precision agriculture.
5m GSD 4-band multi-spectral imagery at 20km swath width
This mode can be used alongside the Panchromatic data to provide high-resolution, pan-sharpened colour imagery. Pan and colour channels are combined to provide colour imagery with an effective resolution equivalent to the Pan channel with is ideal for providing visually interpretable images.
32m GSD 4 band at 300km swath width
This mode provides continuity from NigeriaSat-1. Additionally it can be used to provide cueing information for the very high resolution imager - in other words, it can be used to take big pictures that allow operators to decide where to focus the high resolution imager.
45 degree roll/pitch off pointing
This mode is used to select imaging targets and enables access opportunities to any place on the globe at least once every 2 days.
Downlink speeds of 2 x 105 Mbps
Allows the spacecraft to deliver large quantities of high quality data suitable for selling on the international market.
NigeriaSat-2 is specifically designed to ensure that excellent knowledge of the position of imagery (geolocation accuracy) is possible without any prior information about the target. In other words, ground control points are not required to enable precise knowledge of the position of items within an image.
The high agility of the spacecraft allows a number of physically separate targets to be imaged in the same pass. In this way applications are not limited to one local region each time the satellite passes overhead.
