The RRP 117 ( English : R emote R adar P ost ) is a D-band - phased array radar system of air defense. The operational user in Germany is the Luftwaffe's operations command service . Other radar devices of the Air Force are HADR (radar) , GM 406F and RAT 31DL , they belong to the non-navigational location radio service and are fixed, non-navigational location radio stations .

system

The RRP 117 consists of an air surveillance radar in semiconductor technology (approximately 300 power modules in one antenna), a secondary radar and subsystems for simulation. The RRP 117 delivers 3D target information in real time and correlates with secondary radar data over the entire detection area of ​​around 450 km. The RRP 117 works by vertical beam swiveling with a planar phased array antenna that constantly rotates at six revolutions per minute and is a modified version of the American AN / FPS-117 Long Range Solid-State Radar introduced in 1983 for German requirements . This type was installed at Berlin-Tempelhof Airport as a so-called "Berlin Radar" until around 2005 .

The US AN / FPS-117 is available in various versions in the armaments market, including the modernized version AN / TPS-117 . A total of around 127 pieces (as of August 2006) were exported to the following countries: Australia (since 1997), Belgium, Brazil (since 2009 as TPS-B34), Denmark (since 2007), Estonia (since 2003), Iceland, Italy, Jordan, Canada, Croatia, Kuwait (since 1993), Latvia (since 2003), Pakistan, Romania (since 1998), Saudi Arabia (17 pieces), South Korea, Taiwan, Turkey and Hungary.

Deployment in Germany

Eight radars of the type RRP 117 have been in operation in Germany since 1998. You are subordinate to the Air Force Operations Management Service (EinsFüDstLw):

designation Location Insinuation
Separate technical train 351
(AbgTZg 351) 		Putgarten Mission control area 3
(EinsFüBer 3)
AbgTZg 352 Cölpin EinsFüBer 3
AbgTZg 353 Tempelhof EinsFüBer 3
AbgTZg 354 Döbern EinsFüBer 3
AbgTZg 355 Gleina EinsFüBer 3
AbgTZg 356 Elmenhorst EinsFüBer 3
AbgTZg 357 Döbraberg EinsFüBer 3
AbgTZg 358 Big Arber EinsFüBer 3

The antenna systems are located under radomes to minimize weather influences.
