Norsat® SecureLink™
•	General SecureLink™ Information

Meaning "Very Small Aperture Terminal", VSAT technology is used for a wide variety of telecommunications applications, including corporate networks, rural telecoms, distance learning, telemedicine, disaster recovery, ship-board communications, transportable "fly-away" systems, and much more.

VSAT systems are becoming increasingly popular as single, flexible communications platforms that can be installed quickly and cost effectively to provide telecommunications solutions for consumers, governments and corporations. With more than 500,000 systems operating in more than 120 countries, VSATs are a mature and proven technology.

Clients conducting business in remote, isolated locations need reliable data networks to monitor and control their assets. Transmitting this information to and from remote sites is possible with VSATs that operate where other communications options don't.

AOS manages VSAT data networks specializing in SCADA (Supervisory Control and Data Acquisition) applications for data collection and monitoring of remote customer assets -- such as utility substations or oil and gas pipelines. Along with solutions tailored to any client, AOS provides around-the-clock network monitoring support and reporting to ensure high network availability.

Nortsat® SecureLink™

The Norsat SecureLink is the first complete VSAT system to be designed from the ground up to deliver secure broadband data connectivity in a portable, rugged, and easy-to use package. Only Norsat offers a complete solution - including a carbon fiber segmented antenna, aluminum tripod, 1RU broadband router, network controller, and full Ku-band RF chain with SSPA that packs into just three airline checkable cases.

Norsat is also the first in the industry to incorporate an easy-to-use graphical user interface for antenna alignment, spectrum analyzer, and transmitter and modulator control.
