Abstract: 1410625 Digital transmission; frequency shift keying HONEYWELL INFORMATION SYSTEMS Inc 10 Nov 1972 [9 Dec 1971] 52119/72 Heading H4P A fsk transmitter has a constant amplitude symmetrical triangular wave generator, switchable between at least 2 frequencies and which provides a smoothed transition when switched. The triangular waves may be converted in a square law circuit to substantially a sinusoid. The lower amplitude of harmonics in a triangular wave (relative to a square wave) reduces distortion of a sinusoid produced therefrom eliminating the need for a filter with attendant side band problems of unequal attenuation of differing frequencies i.e. sidebands are effectively preserved. Also change from one frequency to another can be effected without phase change at point of transition. A capacitor 293 is charged at one of a plurality of selectable rates through a constant current circuit comprising transistor 252 controlled by a selected one of resistors 290 (1-n)a being grounded by a transistor circuit, e.g. 270-1a (only one shown) and discharged by a similar set of resistors 290 (1-n)b switched by a similar arrangement, e.g. 270-1b, the charge and discharge circuits being alternately switched by a Schmitt trigger circuit 320, 350 having a dead band of 1 volt above a threshold of 4 volts minimum. Triangular waves amplified at 296 are shaped by a square law arrangement comprising reverse parallel shunting diodes biased to work in anon linear part of their characteristic, the output being fed to inverting input of amplifier 374 and passed to line through driving and isolating transistor 394. A frequency is selected by a signal on one of lines B1-Bn, two of which B2, B3 are energized in response to mark and space signals providing frequencies of 1200 and 2200 cps respectively, one B4 energized by a monostable circuit (244), (not shown) for a short period giving "soft carrier turn off" and the remainder for signalling and control purposes. An arrangement for controlling the generator is described in connection with Fig. 2a (not shown). In an alternative arrangement the triangular waves may be coupled direct to line.

Title: The damping of errors in the computation of velocity or position signals
IPC: G01C21/16
Filed: 1965-12-23
Abstract: 1, 113, 642. Computing velocity and position of a vehicle. LITTON INDUSTRIES Inc. Dec. 23, 1965 [Dec. 24, 1964], No. 54750/65. Heading G1N. In an inertial guidance system, in which errors in the values of velocity and /or position computed from first signals indicative of acceleration and/or velocity are damped by comparison with independently measured second signals indicative of acceleration, velocity or position, steady state errors due to inaccuracies in the second signals are reduced by injecting into the computing channel signals which are functions of the difference between those of the first and second signals which have the same dimensions. The system described has east-west, north-south and vertical gyroscopes mounted on a stabilized platform together with east-west and north-south accelerometers, 54 and 10, which generate first signals indicative of acceleration, corrected at 12, 58 for Coriolis effects. A second signal, indicative of velocity, is derived from ships log 14 and is resolved into north and east components. The north component is differentiated by an amplifier 20 having a feedback integrator 22 and the output is compared at 24 with the output from accelerometer 10 to provide a levelling signal on line 26 indicative of the gravity component sensed by accelerometer 10. The corrected acceleration signal from junction 12 is modified by a factor a, the radius of the earth, and is combined at 32 with a function fo + f-1 of the signal on line 26. The s result is integrated at 36 and combined at 40 with a further function f 1  of the levelling signal. The resulting signal is proportional to the angular velocity of the ship in a northerly direction. This signal is further integrated at 42 to give a value of the latitude of the ship. The levelling signal on line 26 is amplified at 28 and combined with the calculated velocity for controlling the east gyro torquer 30 to level the stabilized platform about the east-west axis. In addition the levelling signal is amplified at 44 and modified as a function of the earth's angular velocity, the easterly velocity of the ship and the latitude, for controlling the vertical gyro torquer to maintain the north-south, east-west co-ordinate system. The output from the east accelerometer is modified similarly, the levelling signal in this case being due to easterly motion of the platform due to rotation of the earth and motion of the ship over the earth's surface, and being applied to north gyro torquer 62. The position signal from integrator 76 is corrected for the earth's rotation to give an indication of the longitude. In a modification Fig. 2 (not shown) the levelling signals are resolved as a function of the computed latitude before application to weighting circuits (34), (38), (70) and (75). The weighting circuits may be analogue or digital circuits.
