  2. Bearing (navigation) - Wikipedia

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

    The bearing angle value will always be less than 90 degrees. [1] For example, if Point B is located exactly southeast of Point A, the bearing from Point A to Point B is "S 45° E". [3] For example, if the bearing between Point A and Point B is S 45° E, the azimuth between Point A and Point B is 135°. [1] [3] Azimuths and bearings.

  3. 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.

  4. Axes conventions - Wikipedia

    Some words commonly used were introduced in maritime navigation. For example, the yaw angle or heading, has a nautical origin, with the meaning of "bending out of the course". Etymologically, it is related with the verb 'to go'. [6] It is related to the concept of bearing. It is typically assigned the shorthand notation ψ. [7]

  5. Heading (navigation) - Wikipedia

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

    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° True ...

  6. Tire code - Wikipedia

    en.wikipedia.org/wiki/Tire_code

    If a tire size has three sets of numbers (15x6.00-6, 26x12.00-12, 31x15.50-15), then the first number (26x12.00-12) is the approximate tire diameter in inches, the second number (26x12.00-12) is the approximate width in inches, and the third number (26x12.00-12) is the rim diameter in inches.

  7. Error analysis for the Global Positioning System - Wikipedia

    In order to compensate for this gain, a GPS clock's frequency needs to be slowed by the fraction: 5.307 × 10 −10 – 8.349 × 10 −11 = 4.472 × 10 −10. This fraction is subtracted from 1 and multiplied by the pre-adjusted clock frequency of 10.23 MHz: (1 – 4.472 × 10 −10) × 10.23 = 10.22999999543

  8. Proportional navigation - Wikipedia

    en.wikipedia.org/wiki/Proportional_navigation

    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 ...

  9. Course (navigation) - Wikipedia

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

    The course is to be distinguished from the heading, which is the direction where the watercraft's bow or the aircraft's nose is pointed. [1] [2] [3] [page needed] The path that a vessel follows is called a track or, in the case of aircraft, ground track (also known as course made good or course over the ground). [1] The intended track is a route.
