Main principles

Data can be collected in real-time or post-processing from our customers’ operational environment, from third parties such as air traffic control, service providers network, airports and airlines, or from ALTYS’s network of cloud-connected sensors, in any type of format. The COSMOS system uses typed data collection techniques, flexible data structures, dynamic information extraction/storage, and multi-step processing. It is based on a scalable distributed cluster architecture using a NoSQL database for storage and processing of up to millions of records per day. The solution may be deployed at the user’s site or provided as a service with unlimited simultaneous remote connections possible.

Users access the valuable information presented by COSMOS via a secure web application. The COSMOS application gives users 24/7 access to a large of analytics tools and functions: reports, statistics, event trackers, alarms, maps, data export, and much more. Additionally, the COSMOS database offers a REST interface for connection to any third-party tool or client API.

The industry’s reference datalink protocol analyzer

APA is a protocol decoder that is used to analyze digital communications traffic. It displays all VHF-based data communications exchanged between ground stations and aircraft, and allows users to visualize all layers of each protocol data unit (PDU). APA is commonly used in conjunction with ALTYS’s test products in support to troubleshooting and performance assessment. APA also is an essential part of the COSMOS platform, enabling both real-time monitoring and post-capture log analysis.

Why use APA?

Monitor traffic of operational ground infrastructures

Identify datalink issues (delays, provider aborts…)

Facilitate datalink problem resolution

Track progress of avionics lab testing and integration

Troubleshoot and understand test failures
