Early navigators used "dead reckoning"—estimating speed and direction over time. This was wildly inaccurate. A ship off course by one degree of longitude (about 60 miles at the equator) could miss a port entirely or crash into rocks.
The longitude of a point is an angular measurement, expressed in degrees (°), minutes (′), and seconds (″), representing how far east or west that point is from the prime meridian. Unlike latitude, which starts at 0° at the equator and is capped at 90° at the poles, longitude runs from 0° at the prime meridian to a full 180° east (positive) or 180° west (negative) before meeting at the antimeridian in the middle of the Pacific Ocean.

The measurement indicates how far east or west a location is from a starting reference point known as the .
Developing a paper on meridian longitude involves exploring the invisible vertical lines that connect the North and South Poles to determine east-west positions on Earth. Unlike latitude, which has a natural starting point at the Equator, longitude is based on an arbitrary Prime Meridian (0° longitude). National Geographic Society 1.

既然经度是测量东西方向的位置，那么就必须有一个起点——这便是“本初子午线”（Prime Meridian），即零度经线。

Before Harrison, astronomers attempted to determine longitude using celestial events:
The shape of the Earth is a rough sphere, meaning it contains a full 360∘360 raised to the composed with power circle. Meridians slice this sphere vertically.
