* Terrestrial microwave equipment: 250 MHz, 70 MHz or 75 MHz

Terrestrial microwave relay, a technology later introduced to link stations, has been largely supplanted by coaxial cable, fiber, and satellite, which usually offer superior cost-benefit ratios.

Terrestrial microwave links, cellular telephone sites, fibre optic apparatus and satellite communications facilities also have standby battery systems, which may be large enough to occupy a separate room in the building.

Examples from the reference source Jane's Military Communications include " text, audio and facsimile ", " Tactical and ground-based communications ", Terrestrial microwave and tropospheric scatter, " Naval and satellite communications systems and equipment ", Surveillance and signal analysis, Encryption and security

To combat them, the Terrestrial Defense Force establishes the, a team of six elite members who utilize high-tech vehicles and weaponry.

Thus for clocks on or near the geoid, T < sub > eph </ sub > ( within 2 milliseconds ), but not so closely TCB, can be used as approximations to Terrestrial Time, and via the standard ephemerides T < sub > eph </ sub > is in widespread use.

For practical purposes the length of the ephemeris second can be taken as equal to the length of the second of Barycentric Dynamical Time ( TDB ) or Terrestrial Time ( TT ) or its predecessor TDT.

Cosmic rays can have energies of over 10 < sup > 20 </ sup > eV, far higher than the 10 < sup > 12 </ sup > to 10 < sup > 13 </ sup > eV that Terrestrial particle accelerators can produce.

Terrestrial planets can have canyons, craters, mountains, and volcanoes.

Terrestrial animals that can only produce ammonia would have to drink constantly, making a life on land impossible ( a few exceptions exist, as some terrestrial woodlice can excrete their nitrogenous waste as ammonia gas ).

Terrestrial landscapes in which the role of biology in mediating surface processes can be definitively excluded are extremely rare, but may hold important information for understanding the geomorphology of other planets, such as Mars.

It can also be rationalised as making the average length of the Martian week close to the average length of the Terrestrial week, although it must be remembered that 28 Earth days is roughly equal to 27 + 1 / 4 Martian sols and not 27 + 5 / 6 Martian sols.

Terrestrial soils of this nature need to adjust from fresh to saline interstitial water by a change in the chemistry and the structure of the soil, accompanied with fresh deposition of estuarine sediment, before salt marsh vegetation can establish.

The Exalted of Creation can be divided into two categories: Terrestrial Exalted and Celestial Exalted.

Celestial Exalted, being the chosen of the Celestial Incarnae, are significantly more powerful than Terrestrial Exalted, and can live for millennia, but their numbers are limited by a fixed number of Exaltations passing from mortal life to mortal life at any given time.

While less powerful, Terrestrial Exalted, or Dragon-Blooded, can pass on their Exaltation to their children, much like one would pass on other genetic features.

Elementals can be summoned through Terrestrial Circle Sorcery, however, unlike demons, powerful elementals often have designated proxies who can be sent to respond to the summoning in their stead.

TDB is now ( since 2006 ) defined as a linear scaling of Barycentric Coordinate Time ( TCB ), and a feature that distinguishes TDB from TCB is that TDB, when observed from the Earth's surface, has a difference from Terrestrial Time ( TT ) that is about as small as can be practically arranged with consistent definition: the differences are mainly periodic, and overall will remain at less than 2 milliseconds for several millennia.

TDB is a successor of Ephemeris Time ( ET ), in that ET can be seen ( within the limits of the lesser accuracy and precision achievable in its time ) to be an approximation to TDB as well as to Terrestrial Time ( TT ) ( see Ephemeris time-Implementations ).

Interactive TV can also be delivered via a terrestrial aerial ( Digital Terrestrial TV such as ' Freeview ' in the UK ).

Terrestrial cell antennas and networks can be damaged by natural disasters.

Lattelecom Terrestrial TV enables digital over-the-air broadcasting of TV signals that can be received using an indoor or external aerial.

PDTV sources can be captured by a variety of digital TV tuner cards from a digital feed such as ClearQAM unencrypted cable, Digital Terrestrial Television, Digital Video Broadcast or other satellite sources.

The multimedia element is able to read HDTV IPTV streams and includes a Terrestrial Numerical Television demodulator, can serve as a home A / V broadcasting station, includes a 40Gb hard drive for recording and time-shifting, and a load of A / V ports.

) After these factors have been taken into account, deviations between the observed arrival times and predictions made using these parameters can be found and attributed to one of three possibilities: intrinsic variations in the spin period of the pulsar, errors in the realization of Terrestrial Time against which arrival times were measured, or the presence of background gravitational waves.

The currently-used standard epoch " J2000 " is defined by international agreement at 2000 January 1. 5 ( or January 1 at 12h on a defined time scale usually TT ), or more precisely the Julian date 2451545. 0 TT ( Terrestrial Time ), or January 1, 2000, noon TT.

In 1917, after several accusations of bribery, LMSA was replaced by Liga Metropolitana de Desportos Terrestres ( Terrestrial Sports Metropolitan League, in English ), usually known as LMDT.

Doing so does not create another version of TAI ; it is instead considered to be creating a better realisation of Terrestrial Time ( TT ).

The instant that the gravitational correction started to be applied serves as the epoch for Barycentric Coordinate Time ( TCB ), Geocentric Coordinate Time ( TCG ), and Terrestrial Time ( TT ).

In 1976 the IAU resolved that the theoretical basis for its current ( 1952 ) standard of Ephemeris Time was non-relativistic, and that therefore, beginning in 1984, Ephemeris Time would be replaced by two relativistic timescales intended to constitute dynamical timescales: Terrestrial Dynamical Time ( TDT ) and Barycentric Dynamical Time ( TDB ).

Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel, mineral wool, expanded clay or coconut husk.

However, there was a movement amongst geologists ( particularly Neogene Marine Geologists ) to also include ongoing geological time ( Quaternary ) in the Neogene, while others ( particularly Quaternary Terrestrial Geologists ) insist the Quaternary to be a separate period of distinctly different record.

Terrestrial salamanders catch their prey by rapidly extending a sticky tongue which adheres to the prey, allowing it to be pulled into the mouth.

Tau Ceti may be a search target for the Terrestrial Planet Finder

Terrestrial testing might be subject to reasonable objections ; as one physicist wrote, " Writing the environmental impact statement for such tests [...] might present an interesting problem ..."

Historical Julian dates were recorded relative to GMT or Ephemeris Time, but the International Astronomical Union now recommends that Julian Dates be specified in Terrestrial Time, and that when necessary to specify Julian Dates using a different time scale, that the time scale used be indicated when required, such as JD ( UT1 ).

On 24 October 2012 Ireland's Analogue Terrestrial signal will be switched off and will be replaced by Saorview which was officially launched on 27 May 2011.

While Terrestrial Planet Finder-C aims to study the planetshine of extrasolar planets, Darwin and Terrestrial Planet Finder-I will search for thermal infrared light that is reradiated ( rather than scattered ) by the planet, and most astronomers would not consider that to be planetshine.

Coming to the end of his tenure at the Department of Communications, Marine and Natural Resources and before the reshuffle after the general election in May 2007 his department pursued the resurrection of Digital Terrestrial Television following its failure to be established under the Broadcasting Act 2001 due to unfavourable economic conditions for venture capital around the DTT market in many countries in 2001.
