摘要： An articulated viewing apparatus (10) has a pair of elevational actuators (56, 78), one of which is a coarse-position actuator (56) and the other of which is a fine-position actuator (78), and each of which pivots a mirror head (28) about respective parallel elevational axes (54, 66'). Pivotal movements of the mirror head (28) direct the line of sight of a viewer looking outwardly through a window (22). The window (22) may be formed in the wall of a vehicle or may be at the upper end of a periscope tube, for example, and includes a transparent material (24). This window (22) may admit light to an optical sensor or to the user's eye directly. The coarse-position elevational actuator (56) is positioned so that its axis (54) is located as close as possible to an edge of the mirror head (28) and close to the inner surface of the window glazing (24) so that the size of the window (22) is minimized with respect to the size of the optical aperture and field of view provided to the user of the apparatus (10). The fine-position actuator (78) is attached to the mirror head (28) at a respective axis (66') approximately at the geometric center of the mirror (28), so that the mirror (28) is statically balanced about the fine-position elevation axis (66') of this actuator (78).

摘要： A vehicle (12) including a control system (18) is used for controlling vehicle attitude or angular velocity (38). The processor (24) is coupled to a star sensor or tracker (22) and a memory (30) that may include a star catalog (32), and an exclusion list (36). The exclusion list (36), a list of stars to be temporarily excluded from consideration when determining attitude or angular velocity or relative alignment of star sensors or trackers, is calculated on board. Such a calculation prevents the necessity for a costly, periodic, ground calculation and upload of such data. By manipulating the star catalog, or sub-catalogs derived from said catalog, based upon the exclusion list (36), measurements of such excluded stars are prevented from corrupting the attitude or angular velocity or alignment estimates formulated on board. The system uses multiple stayout zones for excluding stars from the exclusion list. A central exclusion zone excludes all stars while a second or more exclusion zones allow some stars to be used in the attitude determination

摘要： Attitude acquisition methods and systems are provided which reduce the time generally required to acquire spacecraft attitude estimates and enhance the probability of realizing such estimates. The methods and systems receive, over a time span &Dgr;t, successive frames of star-sensor signals that correspond to successive stellar fields-of-view, estimate spacecraft rotation &Dgr;r throughout at least a portion of the time span &Dgr;t, and, in response to the spacecraft rotation &Dgr;r, process the star-sensor signals into a processed set of star-sensor signals that denote star positions across an expanded field-of-view that exceeds any of the successive fields-of-view. The expanded field-of-view facilitates identification of the stars that generated the processed set of star-sensor signals to thereby acquire an initial attitude estimate.

摘要： An apparatus for determining star location includes a star tracker, a star catalog and a controller. The star tracker is used to sense the positions of stars and generate signals corresponding to the positions of the stars as seen in its field of view. The star catalog contains star location data that is stored using a primary and multiple secondary arrays sorted by both declination (DEC) and right ascension (RA), respectively. The controller checks the star catalog and determines which stars to track. The controller does this determination by using an algorithm to sort the primary and secondary arrays to determine which stars are located in the star tracker field of view. The controller then commands the star tracker to track these stars and uses them to determine the spacecraft attitude.

摘要： A FLIR boresight alignment system (52) for aligning a sensor pod LOS associated with a weapons pod of a fighter aircraft to a navigation reference frame. A pod inertial navigation and global positioning system (62) provides position, velocity and attitude of a sensor (58) within the pod. An aircraft inertial navigation and/or global positioning system (68) provides position, velocity and attitude of the aircraft. The sensor position and velocity and the aircraft position and velocity are applied to a transfer alignment filter (64) that utilizes Kalman filtering. An output of the transfer alignment filter (64) is applied to a sensor inertial navigation system to correct the pod LOS relative to the navigation reference frame. Alternately, the transfer alignment filter (64) may operate directly upon the pseudo ranges and delta pseudo ranges to satellites being tracked by the GPS receiver.

摘要： A cryogenic cooling system having a mechanism for canceling vibration at a fundamental frequency and at harmonics thereof. The inventive system includes a first apparatus (28, 32) for cooling a mass. The first apparatus (28, 32) creates a vibration at a first frequency and a second frequency. In a typical application, the first frequency is a fundamental frequency and the second frequency is a harmonic of the first frequency. Often several harmonics are present. The invention includes a second apparatus (30, 34) for substantially eliminating vibration at the first frequency and a third apparatus (48, 50) for substantially eliminating vibration at the second frequency. The second apparatus includes a mass (30) and a motor (34) for driving same. The mass (30) is disposed to counter the vibration created by the first apparatus when the motor (34) is driven by a first current. The third apparatus includes a sensor (48) for detecting the vibration at the second frequency and providing an output in response to a sensed force F resulting therefrom. The third apparatus further includes a feedback circuit (50) for providing a second current for driving the motor. The second current is the sum of the first current and a feedback current I.sub.b2. The feedback current I.sub.b2 is equal to -G.sub.f (s)F, where -G.sub.f (s) is a feedback transfer function. The feedback transfer function is a product of a first transfer function H.sub.I (s) representing dynamics of the second apparatus required to cancel the vibration at the first frequency and a second transfer function G.sub.D (s) representing the dynamics of the second means required to cancel the harmonic vibration.

摘要： Time-of-day tracking with INS input is described. In one embodiment, a range rate and a range acceleration is generated from inertial navigation system data received from a moveable platform (e.g. an airborne platform). A time and frequency estimation filter receives the range rate, the range acceleration and a timing-based error signal from a time discriminator, and can then generate a time-of-day correction signal and a frequency correction signal. A time-of-day generator receives the time-of-day correction signal and generates a time-of-day correction, and a clock frequency generator receives the frequency correction signal and generates a frequency correction. The time discriminator receives a satellite synchronization signal from a satellite, the time-of-day correction from the time-of-day generator, and the frequency correction from the clock frequency generator. The time discriminator initially generates the timing-based error signal from the satellite synchronization signal, and subsequently generates the timing-based error signal from the time-of-day correction and the frequency correction to synchronize the satellite with the moveable platform.
