BSG-2P
Gyro-Vertical Comparison Unit
Description
BSG-2P gyro-vertical comparison unit
BSG-2P is an aircraft gyro-vertical comparison unit used in attitude-reference and automatic-flight-control equipment. Aviation catalogues identify it as part of ABSU-154-1, ABSU-154-2 and SAU-1T systems. Documented aircraft applications include Il-62, Il-76, Il-86, Tu-154B and Tu-154M; the exact assembly and modification must be checked against the aircraft records.

Function in the attitude-reference system
The unit compares signals from the installed gyro-vertical channels and participates in monitoring their agreement and serviceability. In the documented Il-76 installation, three TsGV-10P gyro-verticals provide attitude references, while BSG-2P works with the comparison, warning and reset logic. It is not itself an attitude indicator or a gyro sensor.
Associated equipment on Il-76
Il-76 maintenance documentation checks BSG-2P together with the TsGV-10P gyro-verticals, BKK-18 bank-comparison unit, KPP-75S and UKT-2 attitude indicators and SNP-1 power-failure annunciator. The panel control provides CHECK and RESET functions, and the corresponding annunciation confirms the monitoring circuit response.
Identification and technical limits
The primary designation is БСГ-2П, transliterated BSG-2P. Public operational material confirms the function and equipment relationships but does not provide a reliable standalone supply, pinout, dimensions or mass. These values must come from the BSG-2P passport and the applicable ABSU/SAU wiring manual. Do not substitute BSG units without matching the full suffix, connectors and system execution.
Inspection, functional check and ordering
Inspect the enclosure, mounting frame, connectors, contacts, seals and data plate. Functional verification is performed in the complete attitude-reference channel using the aircraft CHECK and RESET procedure or an approved bench equivalent. An enquiry should specify BSG-2P, aircraft type and modification, ABSU/SAU execution, quantity and required documentation. Related avionics are collected under Electronic Control Units.
