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 .
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°
Instruments used to plot a course on a nautical chart. In navigation, the course of a watercraft or aircraft is the cardinal direction in which the craft is to be steered.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.
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.
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.
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]
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
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)
