As of 2011. The launch was originally promised in 2009 and later in 2012-2013.
ARKON-2
The spacecraft is designed to perform round-the-clock global Earth surveillance with high resolution in radio-frequency ranges Х, L, P regardless of meteorological conditions.
ARKON-2M
The spacecraft is designed to perform the Earth surveillance in X-band. Application of on-board active-phase array assures high resolution and performance.
ARKON-VICTORIA
The spacecraft is designed to perform high-periodical surveillance providing imaging in panchromatic and in six spectral zones, including simultaneous imaging in any three zones.
SAR Systems Arkon-2 (Russia):
- (a) The original Arkon-1 satellites were equipped with hi-res optical imagers.
- (b) The two new Arkon-2 satellites are being built for Roskosmos by Lavochkin and will be equipped with SAR imagers.
- © The SAR imagers are being built by Vega Radio Engineering Corp.
- (d) These operate at 3 different wavelengths – in X, L and P bands.
