ephemeris

We have to acquire the following "tools" to work with: an ephemeris for the year the horoscope is to be made.

Summary: Pocket Stars is an astronomy application featuring an integrated star chart, ephemeris, and celestial navigation calculator.

The main contents of this paper include: 1. The precision test algorithm of the satellite broadcast ephemeris and orbit determination.

After comparison with overlay pass, other ephemeris and propagation, it was analyzed the orbit determination and propagation accuracy of LP.

The ephemeris of GPS satellites and the coordinates of the satellites are the mathematical basis in solving the GPS baselines.

You may use the on-line New Object Ephemeris Generator to generate ephemerides to enable you to find the object after the first night.

ASPECTS FORMED TO THE PRIME SIGNIFICATOR in the ephemeris from day to day or from week to week, as the case may be.

Devices and methods are described for determining position information without broadcast ephemeris data for extended time periods.

The system in 1964 after he completed the U. S. military use in 1967 will be declassified Ephemeris and the provision of civil service.

Supposing we wish to make a horoscope for a native born August 3rd 1901, we have to buy an ephemeris for the year 1901 at some book store.

With enough satellite ephemeris parameters 1-level data can be got by systematic correction.

The broadcast ephemeris , which is the basic of satellite navigation, must be precise and real time.

Person finally will become greenery be the ephemeris normal regulation.

Using the precise ephemeris and the precise satellite clock correction can realize the precise point positioning(PPP).

The coordinates of the satellites are got according to the broadcast ephemeris received.

And then, the precision test for the broadcast ephemeris and orbit determination are put forward; 2.

The scheme can anticipate user's location by using ephemeris message.

The storage mode in the microprocessor of the data which needs to preserve in advance, such as initial ephemeris etc, is also studied. 4.

used to forecast the next few months which the approximate location of the satellite ephemeris;

secondly, acquiring complete ephemeris data by utilizing the received satellite signals, and calculating a coordinate of the GPS receiver;

the storing device is used for storing and renewing the demodulated ephemeris and almanac information and the almanac correction parameters;
