NORMARC Landing Systems

NORMARC landing systems have been an industry benchmark for more than 30 years. Well over 100,000,000 safe landings have been carried out with help from NORMARC at nearly 1100 airports worldwide.

The NORMARC 7000 Instrument Landing System (ILS) is designed with the customer’s requirements in mind. Through careful preparation in our factory, we manage to considerably reduce the complexity and amount of time the field engineer spends on fine-tuning. This reduces installation and commissioning costs significantly and offers the customer high lifetime value.

Recognizing the need for a sustainable solution, the NORMARC 7000 ILS adapts effortlessly to the steady increase in traffic at airports. Upgrading from a Category I to Category II/III airport with the NORMARC 7000 ILS is simple and cost-effective, supporting long-term growth success.

Whether the airport is large and complex or has relatively few passengers, the NORMARC 7000 ILS is sure to meet all demands and safety regulations -€“ even in the harshest climates. The NORMARC 7000 ILS sets performance standards and boasts a leading market position, allowing for maximum benefit from decades of technical expertise and professional experience. The world’€™s leading aviation authorities have certified the product for its reliability.

Normeka AS, a subsidiary of Indra Navia, contributes to the renowned quality of NORMARC Instrument Landing Systems, adding its competence and experience to the production of NORMARC Frangible Masts by Amplisafe® and other related equipment.


Today, NORMARC satellite landing systems are used in a wide range of airports, including 17 in Norway – one of the world’s most rigorous and challenging environments. The robust design of the new system is based on decades of experience with Instrument Landing Systems (ILS) and Special Category 1 GPS-based landing systems.

Leading the World in GBAS

Instrument Landing Systems work perfectly well at most airports. However, the signal can be affected by topography and other barriers. NORMARC 8100 is our new, Ground Based Augmentation System. This landing system provides highly accurate guidance for aircraft. Its development is rooted in the world’s first GPS-based landing system used for regular commercial traffic. We started work on the world’s first commercial satellite-based landing system in 1996 and it was approved and became operational in 2005. Our new and innovative NORMARC GBAS (Ground Based Augmentation System) was developed from the world’€™s first GPS-based landing system in operation.

GBAS sends data packets, so there are no critical areas similar to an ILS. The two technologies are complementary: smaller airports will use ILS where appropriate; whereas larger airports might start implementing GBAS on one or two runways, with ILS on another runway for older aircraft. GBAS gives operational benefits on the runway,€“ such as closer separation and easier movement of aircraft. The new system can provide precision approaches in order to reduce the risk of diversion, cancellation and go-around.

GBAS operation also requires equipage of aircraft. Typically, newer mainline aircraft are equipped with GBAS receivers, or can be easily retrofitted. However, older aircraft will typically continue to use ILS for approach and landing for several decades to come.

Fifteen years of experience with GPS-based landing systems makes Indra Navia the industry’s most trusted and reliable GBAS partner.




  • Cost effectiveness: Siting flexibility and a reduced need for flight inspection makes GBAS a very cost-effective alternative for the future. One installation per airport enables efficient maintenance solutions.
  • Greater capacity and efficiency: Our system can reduce the separation needed between aircraft and is unhindered by sensitive areas (ILS can have sensitive areas due to terrain/buildings). Thanks also to a choice of different glide paths offered dynamically by the NORMARC 8100 GBAS, wake turbulence will be less of an issue in respect to separation.
  • Increased accuracy: GBAS reduces delays caused by ILS sensitive areas and reduces the risk of large aircraft impacting the signal.
  • Environmental benefits: GBAS enables steeper and shorter approaches and glide paths with different angles. This also helps to reduce noise, fuel consumption and CO emmissions.
  • Enhanced safety: GBAS can provide precision approaches on airports where this has not been possible, for instance due to terrain. Also, since GBAS does not have critical/sensitive areas on/by the runway, it is not prone to operational irregulaties that sometimes occur on busy runways, potentially causing deviations on the ILS localizer.
