Unlike the standard Nautical Almanac, this next-generation Nautical Almanac does not require you to look to other pages to calculate GHA or Declination (except for stars). Although it might be confusing for first-time users, once you get used to it, it is surprisingly easy to handle. For example, when calculating the Sun's GHA, you can simply find the value from the Nautical Almanac page for the day and add UTC. There are also pages which list the sunrise and sunset times for major ports. So you do not have to calculate them from latitude and longitude.

In addition, the celestial coordinates are calculated without omitting the adoption of NASA Jet Propulsion Laboratory's DE440T and the effects of relativity, such as the bending of light due to the gravitational field and the delayed arrival of light, as well as the effects of relatively low-mass celestial bodies such as Mercury, Venus, Mars, Pluto and the moon, which are not normally considered. The time system used in the calculation is also designed to maximize accuracy, and we are proud of boasting high accuracy of celestial positions.
