## MSG Internet Service

**1)****  ****a "closed" Internet service for all LRIT image data**

**To facilitate reception by low cost station users, the entire half-hourly LRIT image data (five channels) could be offered through a ****password-controlled Internet service.****  **
**Licensing and related fees for commercial users would follow the standard data policy, including licensing through EUMETSAT Licensing Agents within Member States, but the need to procure expensive receiving equipment would  be avoided.**

## MSG Internet Service

**2)  a ”public" Internet service with a reduced set of Images**

**The public Internet Service would address the needs of the**
**general public and those users who do not need controlled access of all LRIT image data. **
**This service would be attractive, but not so valuable in the commercial sense.  **

## MSG Internet Service

**The “public” Internet Service could contain the following**
**elements (TBC):**

**- all "essential" image data (six-hourly images from 12 channels) in real-time;**
**- hourly (Europe domain) and three-hourly data (full-disk domain) from four spectral channels in real-time;**
**- image size reduced to 800 x 800 pixels;**
**- graphical format using lossy compression to ensure that data is only suitable for qualitative applications;**
**- effective spatial resolution after compression in the order of 15 km;**
**- image animation loops, image colouring, addition of coastlines/grids;**

## Science Payload: GERB Instrument

**Measurement of earth radiation budget parameters (broadband measurements, horizontal resolution of ~ 50 km)**

## GERB Imaging Principle

** ****a short wave band of 0.32 - 4.0 ********m**
** ****a total wave band of  0.32 - 30.0 ********m **
** ****an inferred long wave band of  ****4.0 - 30.0 ********m (by subtraction)**

**GERB Imaging Principle**

## Encryption: Objective & Scope 

## Encryption: Implementation

- •

**The LRIT and HRIT channels will be encrypted**

**using the so-called “3DES” algorithm**

- •

**This will be managed and controlled by the Key**

**Centre located in the MSG Ground Segment. The**

**system allows:**

- –

**to split data into groups, which are encrypted with**

**different keys**

- –

**to provide users with their dedicated Keys for their**

**Station Key Units (**

**SKUs**

**) via the HRIT/LRIT dissemination**

**service**

- •

**Encryption is the mechanism to implement**

**EUMETSAT’s **

**Data Policy**

## The EUMETSAT Principles on Data Policy

- The EUMETSAT Principles on Data Policy apply to both Meteosat and MSG Data and Products.
- The Principles are detailed in MSG Implementation rules.
- The MSG Implementation Rules follow the Meteosat Implementation Rules very closely.
- The only differences result from the different service capabilities of MSG (eg. 1/4 hourly data sets, LRIT/HRIT).

## The MSG Data Policy

**1.****	****Essential data and products are available on a free ****	****and unrestricted basis as defined in WMO ****	****	****	****Resolution ****	****40 (Cg XII):**
**Six-hourly LRIT Data (5 Channels);**
**Six-hourly HRIT Data (12 Channels);**
**MSG public Internet Image formats;**
**MSG Derived Products**:
**Atmospheric Motion Vectors, transmitted through GTS and LRIT;**
**Clear Sky Radiance, transmitted through GTS;**
**Cloud Analysis, transmitted through GTS and LRIT;**
**Cloud Top Height, transmitted trough LRIT;**
**Cloud Masks, transmitted trough LRIT;**
**Tropospheric Humidity, transmitted through GTS and LRIT;**
**Total Ozone, transmitted trough GTS and LRIT;**
**any further derived product approved by Council.**
- 2.	**Archived MSG Data and Products are provided ****	****	*****free of charge to all***** categories of users.**

## Access to MSG Data by NMS of Non-Member States

**3-hourly MSG Data without charge for Official Duty Use;**
**All MSG Data without charge for Official Duty Use by NMSs of countries with a GNP/C below 2000 $ (increase subject to review) ;**
**MSG Data at a fee for Official Duty Use by NMSs of higher GNP/C;**
**All MSG Data without charge for NMSs of countries subject to tropical cyclones (Official Duty Use only);**
**All MSG Data without charge to monitor disasters/emergencies (limited periods, in accordance with relevant UN Resolutions);**
**MSG Data on a quid pro quo basis for NMSs of countries providing equivalent satellite data to EUMETSAT under conditions to be agreed by Council;**
**Same conditions as service providers for commercial activities by NMSs  of non-Member States.**

## Access to MSG Data by other Users

**All LRIT/HRIT data available without charge for scientific research and educational use;**
**Access to LRIT/HRIT data against a fee for commercial and other users (end users, service providers, broadcasters);**
**Price level for HRIT is the same as current HRI price level;    LRIT fees are 25% lower.**

## Encryption: Station Key Units

- •

**A Station Key Unit (SKU) is:**

- –

**a board with electronic devices**

- –

**containing a programmable micro-controller chip**

- –

**with an own power supply**

- –

**an RS 422 interface cable**

- –

**in a box of ~ 12x10x6 cm**
