Lasers have been considered for space communications since their realization in 1960. However, it was soon recognized that, although the laser had potential for the transfer of data at extremely high rates, specific advancements were needed in component performance and systems engineering, particularly for space-qualified hardware. Advances in system architecture, data formatting, and component technology over the past three decades have made laser communications in space not only a viable but also a attractive approach to intersate ....etc

INTRODUCTION:
MINS is an IP based solution that shall be designed to cater to a subscriber base of around 1000 subscribers. It shall support all the features and functionalities provided by the legacy switching systems.
MINS was required as the rate of the ?Qualcomm chipset ?for the BSC (base station controller) was rising day by day. Qualcomm company is extracting 5$ per subscriber from any Indian company for using their chipset that why in MINS, BSC is constructed not using any hardware but by bin ....etc

The communication needs of Earth observation satellites is steadily increasing. Within a few
years, the data rate of such satellites will exceed 1 Gbps, the angular resolution of sensors will be
less than 1 μrad, and the memory size of onboard data recorders will be beyond 1 Tbytes.
Compared to radio frequency links, optical communications in space offer various advantages
such as smaller and lighter equipment, higher data rates, limited risk of interference with other
communications systems, and the effective use of freque ....etc

In summer 1977, ESA placed the first technological study contract in the domain of intersatellite optical links. Now, twenty years later, a major milestone has been reached with the SILEX laser terminals having been flight tested for integration with their host spacecraft. At the same time, ESA is preparing itself for a new challenge: the potential massive use of optical cross links in satellite constellations for mobile communications and global multimedia services. This is an opportune moment to look back at the past twenty years of ESA effor ....etc
