iFerret (Stratech) locations at Changi

A Stratech Presentation appeared online today containing details of their installation at Changi International. You can download the presentation here.

Stratech state in their presentation that a tower located at 250m from the runway center covers a runway area of 340m by 60m.  Using basic trigonometry it’s therefore possible to calculate the maximum range over which any sensor is expected to operate effectively, this range is 302m, Stratech state that at this range the system consistently detects FOD up to 4cm in size (no mention of color, which is clearly important for a system based on cameras). This is useful information for any airport considering this system as it would enable them to do a basic site design using software such as Google Earth.
