Content


■ Nationally owned military systems with own ‘military’ space capacity in SHF/X-band enabling connections within theaters and between theater and home territory via global & theater beams. In specific casescapabilities are provided on a service basis.

■ Transportable land terminals within theater beams act as anchors for local sub-networks

■ Shipborne terminals within global beam connect larger naval vessels with the overall system

■ ‘Military’ capacity can be complemented by leased ‘commercial’ capacity at C- and Ku-Band to obtain additional global and theater coverage (in extreme cases up to 80% of total capacity used)

■ Transportable land terminals provide mainly local anchor functions

Status of Wideband Secure Communications


■ The available infrastructure does not lend itself to the support of applications requiring near real-time acquisition and distribution of larger data-volumes

■ The currently required terminal sizes limit the mobility of users and exclude small units from direct access

■ Non-military governmental users are normally excluded from use of the system

■ The use of ‘commercial’ capacity is limited by the availability of suitable coverage/bandwidth especially in case of high data rate demand and short notice. Their use is excluded for some sensible applications

■ Implementations of additional space capacities within the classical bands have to face the severe problem of spectrum congestion

■ National procurements of complete systems infrastructures have to face the severe problem of budget limitations and longer procurement timescales

Limitations of Current Approaches


■ Provision of cost-effective, secure communication services for European users in theaters and at home combining European requirements (reduction of customers investment needs)

■ Support of existing military systems via provision of space capacity on demand offering flexibility for such customers

■ Support of gradual, evolutionary extensions of existing militarysystems by true wideband services

■ Provision of wideband secure communication services to non-military, governmental entities

ESS WISCOM Approach


■ Near real time backhaul and/or distribution of large data volumes

■ Video-based applications

■ Distribution and exchange of protected data

■ WLAN-type communications with small disadvantaged terminals in remote, deployed theaters

Targeted Applications

I ITDLTDL

Computed Tomography (CT) Scanner


■ Real-time relay services for large volume data from sensor platforms to home area authorities (BLOS)

■ IP-based communications services for small, disadvantaged terminals

■ Provision/Leasing of additional space capacity for the ‘classical’ frequency bands

■ Coverage of Europe and remote theaters of operations

Targeted Services


■ Connectivity is provided on demand- Satellite and System Monitoring, Control and Resource Allocation by

Service Provider via dedicated SCC and NOC- Gateways to User Networks are either owned and operated by the

user or the service provider, if desired- User terminals are owned and operated by the user or supplied by

the service provider

■ Core Communications is established via military Ka-Band links using new dedicated space capacity

■ Extended Communications is established via- Additional optical links for LEO sensor platforms using new,

dedicated space capacity- Additional SHF/X-Band links for legacy terminals using new

dedicated or existing space capacity- Additional ‘commercial’ capacity using existing space capacity

Conclusions

■ The introduction of true wideband secure communication services for military and non-military, governmental users requires an evolutionary approach for which a comparably small, initial space capacity is of interest.

■ Embarking communication elements of the described architecture on-board a Small-GEO can offer interesting opportunities

- to validate innovative services and applications- to prove full flight-qualification of required payload technologies - to provide early access to the new services- to obtain one element of the overall WISCOM architecture

■ As both technologies and operational concepts go significantly beyond established schemes and require substantial investments, the user community needs to be convinced by a successful in-orbit demonstration and validation of end-to-end solutions

■ Enabling public-sector contributions to space, ground and user segment are considered vital at this introductionary stage
