RSP-2ST NEW GENERATION RADAR

PRECISION LANDING SYSTEM

CHELYABINSK RADIO PLANT “POLET”RUSSIAN FEDERATION

Radio Plant “POLET” (“FLIGHT”) has been established inChelyabinsk in 1952 by the government of the USSR as the majormanufacturer of complicated radio engineering groundequipment for air traffic control.

• POLET manufactured and supports over 90% of radars installed inRussian airport

• 180+ airdrome surveillance radars DRL-7 (RSP-10), AORL-85, AORL-1AS

• POLET ATC aids are successfully operated in all Moscow and in St.Petersburg airports

Moscow Chelyabinsk

“POLET” was the only manufacturer of surveillance radars used tobe part of the basic Russian radar precision landing systems RSP-6,

RSP-10

According to documents on the safety in international aviationindustry, the principal amount of aircraft accidents is happeningon the stages of approach and landing. At the same time anapproach without ground control using precision landing radarsystem is five times more dangerous than PAR controlledapproach. This underlines the urgency of solving the problem ofground controlled approach, especially in airdromes operated byAF, aircraft R&D and manufacturing factories, and generalaviation.

Radar precision landing systems of previous generation weredeveloped in the late 1960’s - early 1970’s and manufactured untilthe end of 1980’s. Currently, the majority of them have exhaustedspecified service life and entirely outdated. They use a vacuumtube components and antennas with mechanical scanning. Thereis no secondary processing of radar data, operation in certainfrequency range generates interference to television and mobilecommunication.

POLET offers the radar precision landing system of new generationRSP-2ST (fixed-based)

RSP-2ST is intended for air trafficcontrol in approach and terminal areausing ground command, accuratemeasurement of deviation of theaircraft from prescribed line of descent,and transmission of control commandsto the aircraft during landingoperations.

COMPONENT PARTS• Airdrome surveillance radar AORL-1AS• Precision approach radar PRL-2ST• Remote terminalOPTIONAL PARTS:• Automatic direction finder (ADF)• Automatic flight control system• Communication facilities• Standby diesel power supply station

RSP-2STRADAR PRECISION LANDING SYSTEM

Radar data is transmitted to control tower by redundant digitalcommunication links. Ways of data transmission are agreed with thecustomer. Equipment transmitting onboard deviation of the aircraft fromprescribed line of descent in ILS format can be supplied as an option forairports not equipped with ground ILS.

The radar display isshown when themoving targetindication (MTI)system is off . Intensereflections ofmeteorological clutterand terrain featuresare observed on thedisplay.

The use of originalMTI algorithm inprimary channelmakes it possibleto eliminate theinfluence ofmeteorologicalclutter and localobjects on theperformance ofmoving targetsdetection.

At the same time,the movingtargets with zeroradial velocityare reliablydetected.

SURVEILLANCE RADAR (PSSR)Specifications of secondary channel

Primary radar equipment of PRL-2ST is used to determine theposition of an aircraft during final approach, in terms of lateraland vertical deviations relative to a nominal approach path, andin range relative to touchdown. Precision approach radars aredesignated to enable pilots of aircraft to be given guidance byradio communication during the final stages of the approach toland.Precision approach radars provide descent and landing of anytype of aircraft till height of about 60 m.The use of remote indicators installed in control tower provides ahigh degree of flight controller’s awareness and efficiency ofissued air traffic situation data.
