Description: The Network Time Protocol (NTP) is used to synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. It provides client accuracies typically within a millisecond on LANs and up to a few tens of milliseconds on WANs relative to a primary server synchronized to Coordinated Universal Time (UTC) via a Global Positioning Service (GPS) receiver, for example.

Description: A satellite is any object that orbits another object.
In popular usage, the term satellite normally refers to an artificial satellite.
A planet, or any other body, which finds itself at any distance from the sun with no "sideways" velocity will quickly fall without missing the sun.-A satellite is any object that orbits another object.

facility used for students learning aids based on the Keplerian Orbit parameters. Three
major areas in Orbital Mechanics are discussed in this paper, Orbit of a satellite, Field
of View of a satellite and Constellation of Satellites. -This paper discusses the establishment and relevant accomplishments of a simple

Description: Very Low Frequency (VLF) spectrograms show
sometimes sets of lines called MLR (Magnetospheric Line
Radiation) with frequency spacing close to 50 or 60 Hz. It is
very tempting to attribute these MLR to Power Line
Harmonic Radiation (PLHR). PLHR are the ELF and VLF
waves radiated by electric power systems at the harmonic
frequencies of 50 or 60 Hz. Here we show for the first
time large scale MLR observed simultaneously on
ground and on board a low altitude satellite which is
flying over the same zone.

Description: This is a compact satellite tracking program. Using it even an older PC (from 486 up, DOS, VGA) can serve to track a satellite and turn the antenna, which allows newer PCs to be used for other purposes. For example other software can be used in parallel to get more information on multiple satellites or contact ranges.
It has the following functions needed in satellite communications:
Tells in which direction the satellite is.
Prints the azimuth and elevation angle numbers to the parallel port for automatic tracking (8 bit parallel data).
Gives pulses to two LPT pins for automatic doppler correction (up / down). -This is a compact satellite tracking program.

Description: ALM2POS computation for satellite position from almanac data file
[pos,R]=alm2pos(almanac,PRN,time) calculates the satellite position in the
Terrestial and in the Celestial reference frame for a desiderate satellite
vehicle (PRN) with almanac data (ALMANAC). The given time (TIME) can be a
scalar or also a vector. Colomn 1-3 of position (pos) are Terrestial
Coordinates (ECEF) colomn 4-6 of position are Celestial Coordinates (ECSF)
in m. Another output is the position vector of the satellite (R) in m.- ALM2POS computation for satellite position from almanac data file

Description: SKYPLOT for a given receiver position
Y=skyplot(X,PRN,C,O) draws the skyplot for the receiver position. The
required inputdata for the calculation of the skyplot X is N-by-3*M matrix,
where N are the timesteps and M is the number of the Satellites. The 1st
colomn is the elevation, the second colomn the azimuth and the 3rd colomn
is the geometric distance between sv and rx [° ° m].
The output Y is the same matrix als X, the only difference is that the
satellites below the cutoffangle are marked (number 9999 is written instead
the Elevation, Azimuth and distance.
The numbers of the satellites are listet in the voctor PRN (M-by-1), C is
the cutoffangle for the satellite elevation (default = 5°). The skyplot
displays only satellites who are visible for more then 10 times.- SKYPLOT for a given receiver position
