STK software

Visiona Technology Espacial has selected Analytical Graphics’ (AGI) Systems Tool Kit (STK) software for Brazil’s defence and strategic communications geostationary satellite (SGDC) development programme.

The software is expected to be used by Telebras Telecomunicaçoes Brasileiras and Embraer Defense & Security joint venture (JV) for satellite orbit design, communications links and communications coverage analysis.

Visiona technology director Himilcon Carvalho said the STK provides key simulation capabilities for any space systems engineering organisation, and will prove to be an important asset in the company’s engineering department toolbox.

”As the Brazilian space systems integrator, Visiona shall rely heavily on it, not only on the SGDC programme but also on the design of future Brazilian space missions,” Carvalho said.

AGI’s CEO, Paul Graziani, said: ”AGI is excited to support Brazil’s efforts to provide a new secure satellite communications system and nationwide broadband services.”

"Visiona shall rely heavily on it, not only on the SGDC programme, but also on the design of future Brazilian space missions."

Developed as a commercial-off-the-shelf (COTS) software tool since 1989, STK is a physics-based software package, designed to help engineers and scientists carry out complex analyses of ground, sea, air and space assets, and share results in one integrated solution.

Previously called the Satellite Tool Kit, the modular software was initially created to solve problems involving Earth-orbiting satellites, but is now used in both the aerospace and defence applications, such as communications systems, radar, interplanetary missions and orbit collision avoidance.

Scheduled to be built by Thales Alenia Space and launched by Ariane 5 in 2016, the SGDC satellite will be operated by MoD on the X-band and Telebras on the K-band.

An integral part of Brazil’s strategy to reinforce its independence and sovereignty, the satellite is primarily expected to enable deployment of a secure satellite communications system for the Brazilian government and armed forces, through the National Broadband Plan (PNBL), with coordination from Telebras.
