Finding the key to unlock airspace

Article Abstract:

Digital datalinks such as the Automatic Dependent Surveillance (ADS) allows the exchange of data on aircraft positions, headings, speeds as a supplement to ground-based radar control systems. The ADS is undergoing testing with the FAA and is dependent upon GPS units for navigation. On the other hand, European air traffic control authorities have introduced the Mode S transponder-based aircraft identification and tracking protocol. Mode S involves selective interrogation with each aircraft having its unique 24-bit address.

Navies enter multi-function radar age

Article Abstract:

Leading Western navies are preparing for the revolutionary switch to the new generation of above water warfare sensors which are the active phased array multi-function radars. Countries such as the Netherlands, the UK, the US, Canada and Germany have all embraced active array-based multi- function radars technology. The naval warfare experts of these countries are confident that this type of radar will progressively leave more traditional radar systems obsolete in a military environment of more pressing threats and increasing uncertainty.

The last line against leakers

Article Abstract:

Ship inner-layer defense systems' development direction is limited to either a gun- or missile-based systems as laser-based technology has yet to reach the operational stage. Inner-layer defense systems (ILDS) are defined by their ability to destroy incoming anti-ship missiles (ASMs) that have penetrated a ship's other layer of defenses and by their ability to defend against low-level threats in the littoral area. Several navies including the Royal Navy of the UK have embraced the missile-based ILDS, believing that this type of system could match the agility of the ASMs.
