SHAPING THE FUTURE OF SATELLITE COMMUNICATIONS

APPLICATION NOTE

SCADA

The ability to remotely monitor, control and

report on the results o distributed assets is key

to achieving maximum operational efciency.

The abundance o measuring and control points

requires an efcient delivery system to balance

network cost versus operational requirements.Beyond supporting traditional SCADA

applications, the industry is looking or ways to

receive real-time visuals rom their remote sites.

By oering an extremely cost eective terminal

as part o a scalable network solution, value

can be provided or operational managers in the

felds o earthquake monitoring acilities, oil and

gas inrastructure, utilities, transport, energy

distribution and environmental monitoring

anywhere in the world. The advent o largescale renewable energy acilities like windmill

parks in inhospitable areas can beneft rom a

SCADA network to optimize efciency o energy

generation and transportation.

How to monitor and control yourbusiness operation in the mostcost eective way.

APPLICATION NOTE

SCADA

Newtecs Sat3Play provides the means to establish an

always-on two-way IP connectivity between a Remote

Terminal Unit (RTU) and the Internet or a private network,

thereore remaining completely independent rom existing

terrestrial networks.

The basic IP connectivity is extended with Quality o Service

(QoS) in orward and return allowing the deployment o real

time services.

The system consists o a gateway that can support up to

50,000 remote terminals with a variety o service levels. Thegateway contains management unctionalities to monitor,

confgure and control remote sites in large geographical

areas. Individual service confgurations can be confgured

to meet specifc requirements o a remote site.

To make satellite an attractive alternative or SCADA the

Sat3Play terminal implements the most bandwidth

efcient technologies, such as DVB-S2 ACM orward

link, 4CPM adaptive return link and embedded IP trafc

enhancement sotware.

Security

Confdentiality o exchanged inormation is guaranteed.

Data can be directly communicated to the RTU using a

single satellite hop. The communication end-points are

authenticated which increases the security o the SCADA

network.

Since the encryption is ully integrated in the system, it can

be combined with trafc acceleration and compression

resulting in real time network behaviour comparable to

traditional delivery networks.

High availability at minimum cost

Newtecs simple, yet very efcient implementation oACM (Adaptive Coding and Modulation), doubles satellite

throughput and customer satisaction by providing 100 per

cent link availability.

ACM technology is incorporated into the DVB-S2 standard,

providing signifcant increases in bandwidth efciency

or satellite applications and allowing modifcation o

modulation parameters o a satellite signal during

almost any orm o intererence, without interrupting the

transmission or losing data.

Since statistically rain ades are short and happen quiterarely over time, higher modulation parameters can be

used most o the time. However, when SCADA requires a

fxed transmission rate or a permanent high availability, the

ACM technology assures that the ade only aects one o

the services. This mechanism gives the platorm extremely

high availability at no additional space segment cost.

Depending on the instant need at a certain location the

required capacity can be variant. The Sat3Play system is

capable o dynamically allocating capacity over the dierent

remote sites.

The gateway provides redundancy on all layers (user,

control, management) and equipment. It has redundant

RF signal and mains supply inputs. The redundancy isconceived as two ully redundant chains. When there

is a ailure an automatic switch over to the other chain

is perormed. Even during service windows there is

limited downtime since upgrades can be perormed

on one o the chains with the other chain active in a

previous version. A ailure in the ront-end is resolved by

switching to the alternative RF input.

Network Scaling

The Sat3Play network supports services ranging

rom data only to voice and video. For many SCADA

applications adding video will provide extra inormation

when abnormal events are detected. Integrating Video

Trafc in the SCADA network will improve operation

efciency by providing greater insight into events and

thus diminishing the potential or damage caused by

emergency events.

APPLICATION NOTE

SCADA

The Sat3Play system can have the

highest amount o terminals active

with real-time response behaviour.

This system eature enables users to

deploy large amounts o terminals ona minimal gateway estate.

The modular and scalable gateway

allows users to start with a small

scale installation, expanding it by

means o a sotware license and

gradually adding additional modules

as the network grows or applications

are added. The unique pay as you

grow principle matches the inherent

changes in size or capacity o the

network with a exible investment

model.

Versatile Service Guarantees

The Sat3Play system provides 3

classes o services: best-eort, high-

priority and real-time. Each o those

trafc classes has specifc transportation and shaping

characteristics. The real-time trafc class assures that

delay and jitter perormance are controlled even in ading

and congested conditions.

In a typical SCADA scenario the high priority class

would be used or the monitoring and control trafc.

APPLICATION NOTE

SCADA

The real-time class would carry the video trafc that

was triggered by an alarm or an operator request. It is

guaranteed that this trafc would not interere with critical

SCADA trafc. The real-time class can also be used or

local technician service calls. The best eort class is thenused or carrying on-site internet or intranet access.

Fast deployment

Sat3Play can be operated as a single service provider

platorm or a multi-service provider platorm. The latter gives

the opportunity to start a service without investing into a ull

system.

The installation o the terminal can be done without any

specifc training. This means a correct and ast installation

can be perormed by a local technician o the remote site

with no need or special equipment. The local technician is

guided to perorm the correct antenna pointing by the Point

& Play tool. The terminal comes pre-confgured so no

on-site administration is required, resulting in ast and riskree deployment.

Take advantage o

the real time service

Fast and risk ree

installation by on-site

technician. No special

equipment needed.

Low power consumption

The terminal only consumes 20W typical and the DC

power supply fts alternative power sources like solar

cells.

The low power consumption o the terminal fnds

its origin in the interactive LNB. It has a simple up-

conversion architecture and uses saturated power

amplifcation without any perormance penalty.
