focusC n General Description (1)<br />
General Description<br />
focusC n is an integrated application that provides full life<br />
cycle support of satellite constellations.<br />
<br />
<br />
It provides a collection of mission independent and mission<br />
dependent functionalities.<br />
Computational layer is based on the extensive reuse of<br />
existing operational flight dynamics systems.<br />
focusC n inherits <strong>GMV</strong>’s vast experience with constellations<br />
flight dynamics software packages.<br />
focusC n uses GUI advance widgets and and generic tools<br />
from focusSuite.<br />

An advanced MMI:<br />
The MMI integrates<br />
advanced widgets and a<br />
design philosophy based<br />
on commercial desktop<br />
applications <strong>for</strong> the<br />
office: “everything-inone-working-area”<br />
and<br />
“all-one-click-away”<br />
(tabs). The MMI<br />
implementation is based<br />
on a proprietary toolkit<br />
called TkForms (based<br />
on tcl/tk) that allows a<br />
development through<br />
configuration files<br />
rather than through<br />
code.<br />

Database driven: All<br />
important mission data is<br />
stored in a database<br />
residing on the server side.<br />
In the standard version of<br />
Focus the relational<br />
database has been<br />
implemented as a set of<br />
standard ASCII files.<br />
Interface between the<br />
database and the<br />
Computation Layer is done<br />
though a dedicated API, in<br />
such a way that the<br />
database data can be easily<br />
ported to a commercial<br />
relational database system<br />
(RDBMS) such as ORACLE.<br />

<br />
The Computation Layer is the bridge<br />
between user and data services. It<br />
responds to requests from the user (or<br />
other computation processes) in order to<br />
execute a process. This protocol insulates<br />
the user from direct interaction with the<br />
database. Two different types of<br />
processes are included in this layer<br />
• The Process Manager is a single process,<br />
receiving requests from the clients and<br />
starting and controlling the computation<br />
processes.<br />
• The Computation Processes are multiple<br />
processes that can run concurrently and<br />
per<strong>for</strong>m the computations needed by the<br />
system.<br />

<br />
The Data Layer maintains, accesses, and<br />
updates data. It also manages and<br />
satisfies requests to manipulate data that<br />
are initiated by computation processes.<br />
Separation of data services allows the<br />
data structure and access mechanisms to<br />
be maintained, modified, or, if necessary,<br />
even redesigned without affecting the<br />
computation or user layer.<br />
Two different single processes running<br />
permanently can be identified in this layer<br />
• The Database API Back-end handles all<br />
the requests received from the<br />
computation processes<br />
• The Relational database (RDBMS).<br />

It handles procedures written<br />
in SoL (Spacecraft operations<br />
language). SoL is a very highlevel<br />
language specially<br />
targeted towards spacecraft<br />
operations which does not<br />
require any previous<br />
programming experience.<br />
