We Make the Impossible Journey Possible

ANPC’s Transponder Landing System (TLS) delivers precision approach, surveillance, and airspace awareness in a single, compact solution. Fully compliant with ICAO and FAA Category I ILS requirements, TLS provides the performance of traditional systems—without their constraints.

Think of TLS as an “airport in a box.” In one standalone system, TLS combines the capabilities of:

• Instrument Landing System (ILS): Precision approach guidance for transponder-equipped aircraft
• Precision Approach Radar (PAR): Ground-controlled approach capability with enhanced accuracy
• Secondary Surveillance Radar (SSR): Detection, tracking, & separation of cooperative aircraft out to 100 nm

Unlike conventional ILS, TLS uses a transponder-based, two-way architecture and ANPC’s Virtual Point Technology to deliver precision guidance without reliance on fixed antenna placement. This enables reliable operations in terrain-challenged, space-constrained, or infrastructure-limited environments—while avoiding multipath interference and critical area restrictions that reduce airport throughput.

Flexible by Design. Deployable Anywhere.
TLS is available across a range of form factors to meet mission needs:

• TLS (Fixed): Permanent installation with minimal footprint and civil works
• TTLS (Transportable): Full TLS capability with rapid setup and no permanent infrastructure
• eTLS (Expeditionary): Highly mobile system designed for military operations, disaster response, and austere environments

To pilots, TLS is indistinguishable from a standard ILS—requiring no new avionics or training. To operators, it delivers unmatched flexibility and a full visual picture of the approach while supporting advanced procedures such as offset approaches, steep glide paths, and operations into confined landing zones.

One system. Total capability. Anywhere you need precision approach and secondary surveillance for aircraft separation and safe landings.
