  2. Bearing (navigation) - Wikipedia

    en.wikipedia.org/wiki/Bearing_(navigation)

    In nautical navigation the relative bearing of an object is the clockwise angle from the heading of the vessel to a straight line drawn from the observation station on the vessel to the object. The relative bearing is measured with a pelorus or other optical and electronic aids to navigation such as a periscope , sonar system , and radar systems .

    5 i is the ranging codes for i; also denoted as I5 n and Q5 n. U and V i are intermediate codes, with U not depending on phase or PRN. The output of two 13-stage LFSRs with clock state t' is used: XA(x,t') has feedback polynomial x 13 + x 12 + x 10 + x 9 + 1, and initial state 1111111111111 2.

  4. Heading (navigation) - Wikipedia

    True course is 120°, the Variation is 5° West, and the Deviation is 1° West. T: 120° V: +5° M: 125° D: +1° C: 126° Therefore, to achieve a true course of 120°, one should follow a compass heading of 126°. True course is 120°, the Variation is 5° East and the Deviation is 1° East. T: 120° V: −5° M: 115° D: −1° C: 114°

  5. List of GM bellhousing patterns - Wikipedia

    en.wikipedia.org/wiki/List_of_GM_bellhousing...

    Also called the GM small corporate pattern and the S10 pattern. This pattern has a distinctive odd-sided hexagonal shape. Rear wheel drive applications have the starter mounted on the right side of the block (when viewed from the flywheel) and on the opposite side of the block compared to front wheel drive installations.

  6. Course (navigation) - Wikipedia

    en.wikipedia.org/wiki/Course_(navigation)

    A navigator determines the bearing (the compass direction from the craft's current position) of the next waypoint. Because water currents or wind can cause a craft to drift off course, a navigator sets a course to steer that compensates for drift. The helmsman or pilot points the craft on a heading that corresponds to the course to steer. If ...

    Note: this is commonly called the Ford Small-block V8 pattern, though it is used in some "big block"-sized V8's as well as some V6's and I6's. 200 I6 1978-1983 only, partial (4 of 6 bolts) pattern. 250 I6 (except Australian 250/4.1) 255 V8; 289 V8 - (made after August 3, 1964) - had 6 bolts holding bellhousing to block; 302 Cleveland (Australia)

    5.307 × 1010 – 8.349 × 10 −11 = 4.472 × 1010. This fraction is subtracted from 1 and multiplied by the pre-adjusted clock frequency of 10.23 MHz: (1 – 4.472 × 1010) × 10.23 = 10.22999999543. That is we need to slow the clocks down from 10.23 MHz to 10.22999999543 MHz in order to negate both time dilation effects.

    The latter uses N ≈ 1.5 with a time delay of ≈ 18 ms, which is adapted to its short-range hunts and helps reduce overcompensation. [5] A guidance law resulting in motion camouflage is used by a number of predator species. By setting up the chase so that the predator either appears stationery relative to background while looming larger (real ...
