Primary Surveillance Radar
Advanced S-Band Solid-State Primary Surveillance Radar Morava 10
PSR Morava 10 is a latest generation primary surveillance radar designed and manufactured by NRPL under ISO 9001:2008 certified quality system. The radar is intended for ATC surveillance within airport terminal area. PSR Morava 10 extended range feature allows using it for en-route application as well. PSR Morava 10 is a field proven PSR system installed at numerous sites worldwide. The system can be flexibly adapted for operation in different environment including wind-farm fields, mountains, and coastal areas. PSR Morava 10 is a very compact and energy efficient solution which reduces demands to installation sites and non-radar auxiliary equipment. PSR Morava 10 fully meets and often surpasses requirements and recommendations of ICAO and EUROCONTROL standards. PSR Morava 10 characteristics were proven by civil aviation authorities of Lithuania, UK, Kazakhstan, South Korea and Czech Republic. PSR Morava 10 is a cost-effective and low maintenance cost solution featuring fully solid-state, highly modular and reliable design with integrated comprehensive BITE system. The radar offers an improved system stability, effective clutter attenuation and elimination of false targets with maintained high probability of target detection up to a distance of 120 NM. High-precise dual-beam antenna ensures reliable coverage within the area and high performance of the radar even under severe ground clutter conditions. Advanced beam switching and combining algorithms mitigate dynamic high-speed clutter such as road traffic, wind turbines and trains. PSR Morava 10 also includes an independent high-resolution weather channel providing precise information on weather conditions (US-NWS 6 level). PSR Morava 10 is very flexible and can be easily integrated with MSSR, ADS-B or MLAT systems. In this case, a common CMS will display status and performance parameters of all systems simultaneously and PPI screen will display combined targets processed by advanced built-in tracking system.

Transportable system
The family of transportable surveillance systems is a further development of the NRPL Unified Comprehensive Surveillance, the concept which is intended to provide the most flexible and cost-effective surveillance solutions for the ATC market. Transportable surveillance systems are mainly dedicated for the following use cases:
- A gap filler for the case of conventional surveillance unavailability due to emergency or an incident such as earthquake, flood, storm, fire, military hostile actions, etc.
- A temporary back-up solution for conventional surveillance systems in case of temporary need to increase reliability and redundancy of radar coverage. This kind of situation can occur when a major international event is held or when adjacent airfield or airspace is temporary closed leading to air traffic intensity increase
- A temporary solution for new airfields when new infra- structure is not yet available
- Reduction of infrastructure building and planning costs
- When land purchase for permanent radar site construction is not economically viable
- A temporary surveillance solution for non-permanent airfields, e.g. airports used during high seasons only or military bases
This class of systems can be easily transported by road, sea or air and rapidly deployed at any location. The system does not require permanent power supply or communication lines and can even include air traffic controller working position equipment to serve as an air traffic control center. The system can be flexibly configured for the end-user needs using number of field-proven subsystems:
- 2.5 m LVA MSSR antenna
- Combined L/S-band MSSR/PSR antenna
- PSR Morava 10
- Mode-S MSSR M10S or IFF
- ADS-B M10AL sensor or MLAT network
- ATC controller working positions
- Voice communications
- Data link
- Power supply system and various non-radar equipment
