SPACE INCREMENTAL VELOCITY GAUGE Russian patent published in 2014 - IPC B64G1/22 G01P3/68 

FIELD: instrumentation.

SUBSTANCE: invention relates to a spacecraft (SC) instrumentation and can be used for high-accuracy determination of minor incremental velocity of the SC progressive motion. The gauge has a hollow spherical body (1) on the outer surface whereof electric magnets (2) are positioned. Position on the body (1) is a network of targeted photoreceivers with an inertial mass (5) contained inside the body. The mass electromagnetic suspension (5) is designed in the form of embedded electric magnets (6) interacting with the electric magnets (2). The mass position sensor (5) represents an optocoupler composed of three optocouples. The radiators in the optocouples are represented by LEDs inside the mass (5) with optic axes (27). Radiation along the said axes falls onto the said photoreceivers of the body. The LEDs are powered from a helium battery embedded into the mass (5). It is charged from currents in the electric magnets (6) windings. The device operation modes are set by the operator (10) via the software (9) control and administration unit (7). Power is supplied from the source (8).

EFFECT: invention technical effect consists in creation of a high precision device (error less than 6%) for measurement of incremental velocity with acceleration of non-gravitational nature in effect equal to approximately (10^-6-10^-10) m/s².
