The precision approach radar system RSP-6M2 is designed to regulate aircraft traffic in the control area of an airfield and to enable approach to the runway of the airfield up to a minimum altitude of 150 to 200 m in poor visibility conditions. With the precision approach radar the further approach up to a decision height of 120 m is possible. The necessary commands for course and glide path correction are transmitted via radio telephony.

The equipment of the precision approach radar system RSP-6M2 includes:

Both primary radars also include an additional secondary radar channel, each operating in the same frequency band as the primary radar. The coding is similar to the IFF-Standard Mark Ⅹ, but contains additional time intervals for national purposes (see MSSR „Krona“).

Since the secondary radar components also use the main antenna, no additional antennas are required. The two long beams at the parabolic antenna as well as the small vertical parabolic antenna above the course antenna have only the purpose of a sidelobe suppression and also serve the interference protection apparatus.
