There may be an additional fee, also agreed upon in the initial lease for exercising your right to stay. Generally, with the exception of the increase in rent, other terms of the initial lease will carry over into the renewal period. Another option you might include is the option for additional space. Being able to expand is key for a growing business. A landlord who sees the potential of having an important tenant that may attract other businesses, especially in a mall or similar retail situation, may be more inclined to grant you an option for additional space.
You will need to examine and negotiate the terms for renting such extra space and make sure the space is suitable to your business needs. The option for additional space may state that you will expand at the same per square foot rate that you are currently paying, at a fixed rate of increase or at the fair market rate at the time of the expansion. This will need to be determined when working out the initial option agreement.
Such an option can only be included if the landlord can reserve or make such space available. A landlord may counter by offering you a right of first refusal, meaning you have first choice on any empty space at the same rental rate that any other tenant will pay. Again, it is a matter of which one of you is in the stronger position. Also, becoming more common in commercial leases is the option to terminate the lease early.
Landlords may offer such clauses to higher profile businesses to entice them to sign longer-term leases and help draw other established tenants into the facility. A transponder is capable of:. When satellites reach the end of their mission this normally occurs within 3 or 4 years after launch , satellite operators have the option of de-orbiting the satellite, leaving the satellite in its current orbit or moving the satellite to a graveyard orbit.
Historically, due to budgetary constraints at the beginning of satellite missions, satellites were rarely designed to be de-orbited. One example of this practice is the satellite Vanguard 1.
Instead of being de-orbited, most satellites are either left in their current orbit or moved to a graveyard orbit. This list includes countries with an independent capability to place satellites in orbit, including production of the necessary launch vehicle. This list does not consider those numerous countries, but only lists those capable of launching satellites indigenously, and the date this capability was first demonstrated.
The list includes the European Space Agency , a multi-national state organization, but does not include private consortiums. A few other private companies are capable of sub-orbital launches. While Canada was the third country to build a satellite which was launched into space,  it was launched aboard an American rocket from an American spaceport.
The same goes for Australia, who launched first satellite involved a donated U. Redstone rocket and American support staff as well as a joint launch facility with the United Kingdom. Both Chile and Belarus used Russian companies as principal contractors to build their satellites, they used Russian-Ukrainian manufactured rockets and launched either from Russia or Kazakhstan.
In recent times [ timeframe? For testing purposes, satellites in low earth orbit have been destroyed by ballistic missiles launched from earth. Russia, the United States and China have demonstrated the ability to eliminate satellites. Due to the low received signal strength of satellite transmissions, they are prone to jamming by land-based transmitters. Such jamming is limited to the geographical area within the transmitter's range.
GPS satellites are potential targets for jamming,   but satellite phone and television signals have also been subjected to jamming. Also, it is very easy to transmit a carrier radio signal to a geostationary satellite and thus interfere with the legitimate uses of the satellite's transponder. It is common for Earth stations to transmit at the wrong time or on the wrong frequency in commercial satellite space, and dual-illuminate the transponder, rendering the frequency unusable.
Satellite operators now have sophisticated monitoring that enables them to pinpoint the source of any carrier and manage the transponder space effectively. From Wikipedia, the free encyclopedia.
