- The implementation of the MSSR-S transportable radar for Peruvian aeronautical surveillance aims to minimize the operational impact of air traffic, and improve detection, tracking and operational safety features using the SCRUM framework.
- As shown in Figure 14, the coverage of the transportable radar and the radar from Lima are very similar up to 150 NM (there is an instrument limitation of 150 nautical, iles for the transportable radar). Starting at 150 NM and flight level 100, the radar from Lima has more coverage over some airways in the lower airspace than the transportable radar.This gap in the coverage of the transportable radar is covered from flight-level 250 by the radars from Cajamarca in the north (airway G675), and the radars from Ayacucho and Arequipa in the south (airways L525 and L302). In both the Lima TMA and the Pisco TMA, both radars have the same radar coverage.
- Surveillance systems continue to constantly evolve with the use of new technologies, continuously improving the detection techniques and data communications, leading to a surveillance system characterized by its optimum coverage, maximum reliability and high availability, the high quality of the information provided, and the minimal cost of exploration.
- The information obtained from aircrafts by surveillance sensors can be essential and elementary (position, altitude and identification), or can involve more elaborate data communications (enhanced surveillance), in all phases of flight and on the ground. A continuous analysis of surveillance sensors is performed to meet the requirements established by ICAO for air surveillance systems. The eight radars, which are part of the surveillance system from CORPAC, are very good in terms of both position and detection. This is achieved through the PASS application.
- The preventive and corrective maintenance carried out by the radar sites has been optimized, minimizing the operational impact and covering the airspace while the radar is out of operation, as shown in the analysis of the results.
