DISS-013 BS-3M
Doppler Navigation Interface Unit
Description
DISS-013 BS-3M interface unit
BS-3M is the interface and indication-processing block of the DISS-013 Doppler ground-speed and drift-angle system. Technical descriptions state that it works with the low-frequency unit computer to process ground speed W and drift angle beta. The designation DISS-013 identifies the complete system context; BS-3M is one of its replaceable blocks.

Signal processing and outputs
BS-3M receives the calculated navigation values and provides them to aircraft consumers in analogue form, through selsyn links and in digital code for electronic indicators. This makes the unit an interface between the Doppler measuring channel, cockpit indication and navigation equipment. It does not contain the entire microwave transmitter, antenna or low-frequency computer.
DISS-013 system performance context
At complete-system level, DISS-013 measures ground speed from 180 to 1299 km/h and drift angle within ±30 degrees at documented heights from 10 to 15,000 m. The system operates near 8800 MHz and includes high-frequency, low-frequency and BS-3M sections. These are Doppler radar system values, not standalone BS-3M electrical ratings.
Aircraft application and associated avionics
DISS-013-S2M is documented within the navigation complex of the Il-76 family. A related catalogue position is the V-2Ts-2 air-data computer; both provide flight information but use different sensors and are not interchangeable. Confirm the BS-3M execution, DISS suffix, connectors and aircraft wiring before replacement.
Inspection, testing and ordering
Inspect the front panel or enclosure, indicators if fitted, connectors, rack attachments, seals and complete data plate. Bench testing requires simulated DISS outputs and the approved interface procedure. State DISS-013 BS-3M, aircraft and DISS execution, quantity, condition and documentation requirements in the enquiry. Related navigation electronics are listed under Electronic Control Units.
