SITA Qualifies Avionica's satLINK Iridium Communications Module Avionica says SITA has qualified its Iridium satellite-based data communications module for use on the SITA ACARS (aircraft communications addressing and reporting system) network. According to Avionica, satLINK is the first Iridium-based communications product to process SITA's VAC (validation, assessment and qualification), meaning that satLINK-equipped aircraft will now have "truly global messaging coverage in addition to voice communications." "No other system can provide equivalent worldwide coverage and reliability", claims Raul Segredo, Avionica's president. "Terrestrial VHF (very high frequency) and HF (high frequency) radio-based networks are unreliable in remote locations and over water, and Inmarsat has no coverage near the poles...." Avionica sees satLINK as augmenting if not replacing existing VHF/HF and legacy satcom. "The Iridium constellation is the ATC messaging backbone of the future," Mr. Segredo asserts. Mr. Segredo continues: "satLINK is designed to fully integrate into existing and future commercial avionics suites. The Iridium constellation's architecture requires a much smaller antenna and far less expensive equipment and installation costs than an Inmarsat solution. The resulting system is approximately 1/10th the price of an Inmarsat installation." 11-08-2007. |
