Since deploying the industry’s first surface multilateration system for the enhancement of ground movement safety at London Heathrow Airport in 2002, Sensis  has supported its customers’ continued growth through numerous expansions of its multilateration systems. This includes adding and/or moving sensors or antennas to accommodate airport construction and expansion projects, enabling controllers to maintain accurate situational awareness of ground operations without the cost of having to deploy a new surveillance system or additional Surface Movement Radar (SMR).
 
Airports are continually adding gates, terminals, and other structures that may affect the performance of an existing multilateration system. Due to multilateration’s extensible nature, sensors and antennas can be moved or added to address these new surveillance needs. By contrast, airport construction projects that affect SMR performance can result in costly repositioning of the SMR or, in some cases, deploying an additional SMR.
 
Sensis multilateration solutions, whether they are deployed for surface or wide area multilateration, as part of an Advanced – Surface Movement Guidance and Control System or Aerobahn® surface management systems, offer the flexibility to meet new surveillance challenges presented by airport construction.
