Wireless GroundLink® System (WGL)

Teledyne Controls’ Wireless GroundLink® System (WGL) enables aircraft operators to fully automate the recording and transmission of their flight data, therefore eliminating all risk of data loss involved with traditional manual procedures. Offering unprecedented reliability, the GroundLink solution is a unique patented system that records and wirelessly transfers flight data from the aircraft to the ground, without any media handling and human intervention.

Using a Teledyne proprietary protocol, the raw data recorded during flight is compressed, encrypted and then transmitted via cellular technology and the Internet to the airline's or Teledyne's ground-based data center for processing and analysis. With the Teledyne Wireless GroundLink solution, airlines can significantly reduce data delivery delays (the data is typically available within 10-15 minutes after an aircraft has landed, versus several days or weeks with manual data retrieval). Additional operational benefits are realized since human resources, equipment costs and data-loss associated with manual retrieval methods are virtually eliminated.
