These satellites can see everything that is happening in every nation on earth. Special focus is on foriegn troop movements.
Sirius

photographic intelligence satellite
perational life of about three years, would be in orbit at all times
sun-synchronous orbits, which repeat their ground tracks at four day intervals, and are synchronized to provide two day overlaps in coverage.

Discoverer II
http://img78.photobucket.com/albums/v245/vetobob/Discoverer_II.jpg
constellation of relatively inexpensive radar satellites designed to affordably provide near-continuous, day/night, all-weather, synthetic aperture radar (SAR) imaging support to the warfighter that could be directly tasked by the warfighter and directly downlinked to theater for processing and exploitation
space-based High Range Resolution Ground Moving Target Indication
near-continuous, deep-look battlefield coverage from space
constellation of 24 satellites configured with Synthetic Aperture Radar (SAR) will allow for direct tasking control to a deployed Joint Task Force [JTF] tactical commander.
allow for a very rapid revisit rate (about 15 minutes) to most areas of the earth. The Discover II system would be capable of generating very high resolution elevation data (1 meter post spacings) and highly accurate radar imagery.

Helios
http://img78.photobucket.com/albums/v245/vetobob/helios.jpg
national reconnaissance spacecraft
$2 billion
mass of about 2.5 metric-tons and operates in a sun-synchronous orbit at an altitude of 680 km and an inclination of 98 degrees. Outwardly, the spacecraft closely resembles SPOT 4 with a box-like bus and a five-segment solar array capable of generating 2.5 kW of electrical power. A 3-axis stabilization system and precision pointing accuracy supports the primary multi-spectral CCD imaging system with a resolution of one meter.
A tiered encryption scheme restricts images to only one or more of the Helios program states
Weight :
2,500 kg
Energy :
Solar generator supplying 2.2 kW
Specified useful life :
5 years
Orbit :
Circular, low altitude (around 700 km), sun synchronous
Ground facilities :
Encrypted control and programming of the satellite from France, image reception and processing in dedicated centres of the 3 co-operating countries
Payload :
Panchromatic, high resolution and wide-angle optical instruments, data storage on digital magnetic recorder, transmission to the ground by encrypted telemetry
Ground segment :
Dedicated Helios control center
Two centers in each user nation (a main center and an image telemetry reception center)
Field stations for image exploitation
A theater station for France
Major operational capabilities :
Minimal delay for return to zone (less than 24 hours in general)
Flexible and confidential programming
Programmation, telemetry reception and image exploitation on the field using the Theatre Transportable Station
